Ice-out: Fun, Facts, and Reality

by Susan Trask, 6/13/2010

The first sign is usually a darkening of the thick dirty gray surface. Then you start to notice some small openings along the shoreline, and perhaps some wet-looking patches scattered here and there. Sometimes it will freeze back solid, but you know that the end of the long, still winter of ice on the lake is not far away.

Winter ice

Ice out April 9th, 2004.  This patch of ice blew into a cove on April 14th that year.

It’s never the same twice. Some years, you will awake to a suddenly-open expanse of water stretching nearly all the way across. Once you have large open patches, a good wind on a sunny day can do away with most of the ice in short order. Other years that darkening effect continues, until the ice gradually disappears. (No, it doesn’t actually sink, although many will insist that it does.) My favorite years are those where the deteriorating ice becomes honey-combed, with long shards that tinkle together when the wind blows like eerie, magical wind chimes.

It seems that each lake or pond has its own tradition of how one actually defines “ice-out.” In an earlier less eco-conscious time, some folks would drive a car out onto a certain spot on the lake and record when it fell through. Many lake watchers define ice-out it less dramatically, say by when one can navigate from Point A to Point B, or merely when the ice is “virtually gone” as the Auburn Water District does. On Taylor Pond, a number of lakeside enthusiasts kept an ice-out pool for many years, whose winner was determined when Jan Marston and Pat Garcia certified that they couldn’t see any ice in any cove. However the various locations define it, nearly everyone in the state noted their earliest-ever ice-out in 2010. This year Taylor Pond beat its previous record, set in 1981, by eight days, clocking out on March 20.

Those of us lucky enough to witness the ice-out phenomenon yearly count it as a real turning point, a sure sign that spring is coming soon, that muddy yards will be dry enough to pick up winter’s debris, that we can begin to look for crocuses peeking through the remaining snow. The earlier the better, right? The docks and boats in sooner, more days of boating, fishing and swimming. What’s not to like?

Here’s where a few facts of lake biology come in. Once the ice is gone, the sun warms the surface of the water and provides nutrients for algae and other plants to begin growing. The lower part of the lake remains relatively cold. Obviously, the more sunny days we have, that upper warmed layer will be larger and the bottom colder layer will be smaller. Since the biological activity of the growing plants depletes oxygen, less of it will be available in the colder layers for fish. According to director of VLMP (Volunteer Lake Monitoring Program) Scott Williams, that warmer upper layer also creates a “more biologically productive environment for algae growth” and the possibility of increased proliferation of invasive plants. (So far, we don’t have any of these on Taylor Pond!)

Some will be quick to conclude that the state-wide recording breaking of ice-out dates is because of global warming. Others will point out that one cannot pin down the data of a single year to a single cause. Whatever the cause, we can certainly enjoy the benefits of our early spring. While we do, however, let’s also recommit to doing all we can to prevent our own actions from further jeopardizing our beautiful resource. Remember, the simple things really count: Keep a good buffer strip, refrain from using phosphorous-laden fertilizers, and control your boat wakes. As we take full advantage of this beautiful season this year, let’s also be sure we do all we can to enjoy many spectacular ice-outs in the future!

Turf Grass Experts’ Top 10 on Lawn care

By Dana Little, June 6, 2010

What could be more beautiful than a healthy green lawn?  Let me suggest some alternatives:  a garden of flowers, a collection of attractive bushes and a buffer strip of untouched land next to the lake for the wildlife.  Why do we worry about lawns running right up to the lake?  Because lawns are the major source of phosphorous run-off into the lake.  In a buffer strip the rain water slowly percolates through the soil which naturally cleanses it of phosphorus.  A lawn maintained right up to the pond’s edge allows rain to wash phosphorous off the surface of the soil directly into the pond.   Fertilizers applied to the lawn provide another source of phosphorous run-off.   Phosphorous in fertilizers is seldom needed and yet, is widely used.  Maine Law now makes it illegal to sell phosphorous- containing fertilizers without notifying customers of the issue.  Fertilizers with no phosphorous can be bought in all local stores and will not harm the lake.

So, if you must have a lawn, here are the experts’ top 10 recommendations:

  1. Fertilize only if necessary, once or twice, best in late August or September and then only on new or young lawns less than 10 years old.  Only one-quarter to half the usual recommended amount is necessary.  Pesticides and herbicides can run off into the pond hurting fish and water quality.  Fertilizers that contain pesticides and herbicides increase the problem that can occur with “fertilizing” the lawn.
  2. Perform a soil test to determine which nutrients are needed.  Seldom in Maine do you need phosphorous or potassium.  Nitrogen is the only common nutrient needed and then not on lawns over 10 years of age.  Mulching the lawn clippings on the lawn and mixing clover into your lawn seed provide all the nitrogen most lawns need.
  3. Mow high, at least 3 inches, for vigorous roots and to shade out weeds
  4. Use a mulching mower that will leave the grass clippings on the lawn for a high-quality, phosphorous-free fertilizer
  5. Plant the right species of grass.  Avoid Kentucky Bluegrass which requires high levels of fertilizer and water and use turf-type tall and fine-leaf fescues.  Grass seed mixtures ideally should include herbs such as chamomile, yarrow and clover.  These “weeds”, often killed off with pesticide applications, take nitrogen from the atmosphere and make it available to the grass.
  6. Keep the grass dense.  Higher density means fewer weeds.  At the first sign of thinning, loosen the soil with a rake and apply an appropriate grass mixture.
  7. On older lawns that have been heavily fertilized thatch can build up.  If the thatch is thicker than ¾ inch it can be reduced by a core aerator that punches holes in the ground or by applying  1/8 inch of compost over the entire lawn which will cause the thatch to decompose.
  8. Water your lawn only if it has rained less than an inch in the last week.  Watering daily encourages shallow roots and an unhealthy lawn.  Water once a week to provide for one inch over the entire lawn using a rain gauge to measure your sprinkler’s output.
  9. Keep fertilizers and clippings off sidewalks and driveways where rain can wash them into the pond.
  10. Keep mower blades sharp to prevent tearing of the grass which promotes disease.

Invasive Plants, Taylor Pond’s Biggest Threat

By Dana Little, July 6, 2010

What worries me the most when I think about water quality on Taylor Pond?  Invasive plants have the ability to irreversibly change the nature of our pond.  I grew up in Massachusetts where many of the lakes are now infested with invasive plants.  I made summertime trips to cousins who lived on a lake in Wisconsin that now is congested with invasives.  All of the “lower 48 states” except Maine have major problems and spend large sums on this problem.  These plants can clog up the water making swimming unpleasant, tangle in boat motors, and die off, at times in large numbers, using up all the oxygen needed by fish.

How easily can they enter the lake?  Less than ½ an inch of a plant is all it takes to become established in a lake.  People who move their boats from lake to lake are the most common source of transfer.  Most invasives first appear near public boat ramps.

How likely are we to suffer an invasion?  Consider the facts that invasives currently live in Lake Auburn, the Basin, the Little Androscoggin River, Range Pond, Sebago and Thompson Lake.  The invasive plants have gradually progressed from southwestern Maine to the north and they ultimately threaten all lakes in Maine.   We are in the direct path of this onslaught.

What can you do to prevent invasion of Taylor Pond?   Never dump aquarium plants or bait fish into our pond.  Inspect any boat placed in the water for attached plants especially small pieces that remain attached to the motor or trailer parts.  Even small dried fragments have been known to come to life and spread an infestation.

Breeding Common Mergansers and Yellow-billed Cuckoos

by Dana Little, July 2009

This year I observed a breeding Common Merganser for the first time on Taylor Pond.  This merganser is a large bird typically over two feet in length with a wingspan of nearly three feet.  The female, which I observed, has a brown head with a short crest behind.  The bill is bright red and serrated to hang on to the fish for which it dives.  The body is a light gray that blends into the background making the mother hard to observe.  My son, Robbie, first saw her carrying three newly-hatched chicks on her back July 12th.  When I saw her on the 13th and subsequent days only one chick remained.  Both mother and chick could be observed swimming along with their head held at water level with the eyes below to spot fish.  One can see this fish-searching behavior often in the Common Loon which is a regular visitor to Taylor Pond.   Whenever the baby merganser startled, it quickly jumped onto its mother’s back and rode away.  The Common Merganser typically prefers deep, clear lakes and rivers and subsists mostly on small fish caught underwater while swimming.  The adults usually nest in a tree cavity near water 15-20 feet above ground and lay 8-11 eggs.  During the winter they can be spotted in the Androscoggin River just below the falls and anywhere along the southern Maine coast.  When the ice melts in the spring this bird is one of the first to make an appearance along with the Wood Ducks and Hooded Mergansers in the open water near the shoreline of Taylor Pond.

Yellow-billed Cuckoos can be heard at this time of year commonly calling in the thickets surrounding Taylor Pond.  This species has declined 42 percent since 1980 according to Breeding Bird Survey data.  I have difficulty spotting the adult as they like dense vegetation but occasionally they can be seen flying around my yard.  They typically lay 4 eggs in a nest found in low shrubs.  The young develop rapidly and are out of the nest within 3 weeks.  The adults love to eat tent caterpillars and cicadas and when large outbreaks of these insects occur, the adults will lay many more eggs than usual.  Although you are unlikely to spot this bird soon, you can detect its presence by learning the song by going to the Macauley Library, Cornell Lab of Ornithology.

The Breeding Aquatic Birds of Taylor Pond

by Dana Little, July 2008

Taylor Pond provides essential habitat to a variety of aquatic birds that depend upon its clean and productive waters.  Standing by the lake one can count dozens of bird species flying over, diving into, or swimming in the pond.  A short hike in any direction away from the pond demonstrates a rapid decline in the numbers and variety of birds.  Fifteen species depend on the pond to raise their young.  They typically arrive as soon as open water appears around the edges and stay until the pond surface freezes solid.

A pair of Canada Geese in recent years has been nesting on the pond.  The male and female will form a pair that lasts for years.  They lay 4-7 eggs and then share in raising the young.  They often will climb onto lawns that reach all the way to the water.  They will forage on sprouting vegetation and insects found on lawns leaving large fecal messes that can be hazardous to people walking on the lawn.  Large flocks stop off to rest on the pond during migration north in the spring and south in the fall.

Bird Geese

A family of Canada Geese

Four ducks commonly breed on the pond:  Wood Duck, American Black Duck, Mallard, and Hooded Merganser.  The Black Duck and Mallard stay year round.  During the winter they swim in openings of the ice on the pond until they close up, and then they move to the AndroscogginRiver or down to the coast.  The Wood Duck and Hooded Merganser slip down to the southern United States for the winter,,  but as soon as open water occurs, they reappear.  The Wood Ducks can be found in the spring sitting in pairs in large trees around the pond.  They like nesting in hollow cavities in old trees, but love it if you provide a nesting box for them.  Nests will often contain 15-20 eggs, sometimes from multiple females. The adults and young commonly forage for small invertebrates in the marshes and swamps around Taylor Pond.  The secretive Wood Duck, although common, takes an alert observer to spot them before they rapidly fly away when approached.  The Hooded Merganser also nests typically in hollow trees or nesting boxes.  Up to 35 eggs, which may be laid by several females, have been found in their nests. Hooded Mergansers have been known to lay their eggs in Wood Duck nests.  Hooded Mergansers have narrow serrated bills to capture the small fish, frogs and crayfish that form the bulk of their diet.  They are secretive birds that are best seen early in the morning or late in the evening diving for their prey in open water.  The Black Duck and Mallard will typically lay 8-10 eggs in a grass lined nest usually found in a remote marshy area.  Once the young hatch they are commonly seen throughout the day on open water of the pond, the female leading and a long line of young following behind.

Common Loon eggs have been found around the pond in the last two years.  However, we have not had a successful chick since Audubon volunteers has been monitoring the pond since 1983.  I suspect that the lack of breeding success has to do with too many houses along the shore, too much boat traffic, and in the last few years, jet skis that regularly buzz the entire shore line.  During the summer a careful search of the pond will usually find 4-6 Common Loons foraging for their favorite food of small fish.  They appear tame and are easily approached in a canoe or may suddenly appear close to you while you are swimming.

Great Blue Herons nest in colonies, the closest one being on an island in the AndroscogginRiver.  At daybreak the Herons leave their nesting and roosting sites to feed in places like Taylor Pond.  During the daytime, Great Blue Herons can often be found standing in shallow water along the shoreline looking for their favorite foods; fish, frogs and crayfish.  One day I watched a Great Blue Heron at the end of my dock work for over one-half hour swallowing a foot long prickly perch.  The much smaller Green Heron typically nests in thickets in marshy areas.  Difficult to find, one usually spots them feeding along natural shorelines, climbing up on overhanging shrub branches, waiting to spear any fish that swim below.

Bird Great Blue Heron

American Bitterns breed in the marshy areas on the side of the pond.  Almost never seen, their presence is most commonly noted by their deep booming calls that have an other-worldly nature to them.  They feed on small fish, frogs and crustaceans found in the marsh or along the sides of the pond.  The Virginia Rail is one of the most difficult-to-spot birds of the pond.  They spend all their time in thickets in the middle of the marsh.  Their unusual call is commonly heard and once you recognize it you may see them walking about low in the bushes.  They are not shy and will parade out in front of you with no apparent fear if you remain still.  When we moved into our home here on the pond, one adult led and one adult followed with 10 young in between parading around the moving vans.  The young look like black, fluffy ping-pong balls on stilts.  Once fully grown they fly off to winter along the southern and gulf coast of the US.

It takes an alert observer to see the common Spotted Sandpipers which are usually seen feeding along the shoreline.  Their constant bobbing and black spots on a white belly identify them.  They breed in the woods and fields around the pond.  They win the prize for aquatic birds flying the furthest as they commonly winter in Chile and Argentina.

Ospreys typically build large stick nests near the water.  I have seen no nests near the pond but they can be seen daily catching fish.  They hover over the water 30-100 feet and then dive feet first to come up with wriggling perch and bass.  The Osprey population plummeted in the 1950’s due to DDT but now they are abundant in Maine.  During the winter, they travel down to the coast and as far south as South America.  The largest bird found on Taylor Pond, the Bald Eagle, has a wingspan typically over six feet.  Their nests can be found on the AndroscogginRiver, but they are regularly seen hunting over the pond.  They feed on fish sometimes stolen from Osprey or snatched from the water.  They also love to feed on gulls, ducks, and small mammals.

When Green is Not So Green

by Anne Goorhuis, May 2007

To be green is to be seen as eco-friendly.  A green choice protects the environment and doesn’t deplete the earth’s natural resources.   Sprinkle the word green in your conversation enough, and your colleagues will begin to view you as an avant-garde who’s into cutting edge, petroleum-saving technologies.  Yes, green is the new adjective to describe an environmentally friendly, sustainable lifestyle choice.  Unfortunately, green is also used to describe grass.

Green grass…sigh!  It conjures up images of barbecues and hammocks.  Green grass seems to summarize what so many of us strive for – beautiful surroundings and the time to enjoy them!  We dream of a golf-course quality lawn and pursue that dream at any cost.  However, there are some underlying assumptions about perfect lawns that do not harmonize well with lakeside living.

The golf-course-quality, green lawn is one of monoculture, where one characteristic is emphasized to the detriment of other characteristics.  The chemical companies have taught us that uniformity of appearance is better than diversity of plant species.   If we sprinkle a little of this or spray some of that, we can get rid of the clover in the grass, for example.  Clover’s broadleaf image doesn’t jive with the slim, anorexic look of a blade of grass.  The lake-lover, however, comes to appreciate clover because of its ability to bind nitrogen to the soil – a kind of self-fertilizer, if you will.  The lake-lover realizes that to use an herbicide to get rid of the clover affects the lake, because the chemicals can leach into the water and cause problems for the fish, which in turn can cause problems for the beings that eat the fish.  DDT is a prime example.

A lakeside environment is one of diversity.  The above example illustrates how sensitive our unique environment is.  This complex interplay is one of the reasons we Taylor-Ponders love living here.  I, for one, get a thrill from watching a Bald Eagle perched on a nearby tree looking for chemically untainted fish!  (And should the fish become tainted, how long until there are no more Bald Eagles?) When we choose to give up the unrealistic dream of monoculture, we say “Yes!” to the multilayered environment that is our home.

So here are a few pointers for those of us who want to walk barefooted to the grill to get our hamburger and still have something grass-like under our feet.

1)     If you’ve got enough sun on your property to grow grass, vow never to use an herbicide on it.  Adjust your expectations to allow a few broadleafs in your lawn.

2)     Let your grass grow to at least 3” in length before mowing and allow the clippings to fall on the lawn to fertilize it.

3)     Only water your lawn if it hasn’t rained in seven days.  In this case, water before 10 a.m. for a longer period of time (30-60 minutes).  This creates deeper root systems on the grass that withstands drought better.

4)     Do not mow within 15 -20 feet of the water.  Instead allow a natural buffer to flourish there.  Even a buffer of 8-10 feet is better than nothing.

5)     If you do not have enough sun to properly grow grass, don’t spend lots of money on useless fertilizers trying to do so.  All those chemicals end up in the lake and you still won’t have that coveted lawn. (A future article will deal with options for the yard with dense shade.)

6)     If your property touches the waterfront, don’t use any fertilizers.  Instead, do not bag the grass clippings and shred your leaves in the fall.  Allow the shredded leaves to lie on the lawn over the winter.  This is a form of natural fertilizer.  For flower and vegetable beds use organic fertilizers such as a compost of leaves, grass clippings and household vegetable waste.

7)      If your property is not contiguous to the lake or a stream that feeds into the lake, and you feel the lawn occasionally needs the burst of a fertilizer; purchase phosphorous-free fertilizer.  Do not apply fertilizer after midsummer, as plant growth then starts to wane in preparation for autumn and winter and more chemicals are therefore leached into the ground table or lake.

TAYLOR POND ASSOCIATION WINS MAINE COLA STEWARDSHIP AWARD

by Michael Dixon, May 2007

Each year, the Maine Congress of Lake Associations recognizes a lake association for its contribution to protecting Maine lakes and ponds.  I am very proud to report that we won the 2006 Outstanding Achievement Award for Lake Stewardship.  The award was announced at the 2006 New England Lakes Conference, held in Farmington on Saturday, June 3.  Dana Little and I attended the conference in order to accept the award.

Award

Maggie Shannon presents the award to Michael Dixon and Dana Little.

I thought I would use this opportunity to tell you all a little about the organization that honored us, by including some information from the COLA website:

What is Maine COLA?

The Maine Congress of Lake Associations (Maine COLA) was formed in 1970 as a non-profit, charitable organization for Maine lakes. It is the only statewide network of individuals and lake associations devoted solely to the protection and preservation of our lakes.

Protecting water quality and promoting sound land-use practices are objectives Maine COLA has had throughout its history. More specifically the purposes of Maine COLA are:

  • To provide a communication network and coordinating structure for      lake-related projects and issues;
  • To provide a clearinghouse of environmental information pertaining      to lake management;
  • To provide a pool of technical knowledge and expertise to advise      and assist members;
  • To promote through education the appreciation and wise use of      Maine lakes;
  • To promote boating and water safety;
  • To establish liaisons with other environmental groups and      agencies;
  • To monitor and report to members on legislation and administrative      actions affecting Maine lakes; and
  • To advocate and support legislation and administrative actions      which promote sound lake management.

What Does Maine COLA Do?

From testifying at a legislative hearing or hosting a conference on sewage disposal to alerting members about important lake issues throughout the state, Maine COLA’s activities are as varied as its accomplishments.

Maine COLA has always had a strong commitment to individual lake associations: how to start one, where to obtain water monitoring equipment, how to reduce erosion. While lake associations have concerns unique to their lakes, there are common statewide problems as well. Maine COLA serves as a resource for both.

We are also active with legislative issues. In the mid-1970’s Maine COLA was influential in obtaining comprehensive legislation regarding dams and water levels, unchanged for centuries, which led to required water levels and better dam safety. Maine COLA is a member of the Great Ponds Task Force, charged with developing a package of recommendations which was passed by the Maine 118th Legislature in 1998. Supporting legislation for the welfare of our lakes continues to be an important component of Maine COLA.

The TPA is a dues-paying member of COLA, but the organization also offers individual memberships.  Please visit www.mainecola.org for more information.

The Gulls of Taylor Pond

by Dana Little May 2007

Officials responsible for LakeAuburn’s water quality decided a year ago that gulls were increasing the bacterial count in Lewiston/Auburn’s water supply.  To reduce this source of pollution, Ben Nugent of Maine Fish and Wildlife Service killed a few gulls.  He also used noise-makers to scare many more gulls off the lake.  Officials successfully reduced the gulls on LakeAuburn and bacterial counts declined to acceptable levels.  However, the reduction in gulls on LakeAuburn appeared to have caused an increase in gulls on Taylor Pond.

This last summer Ben Nugent observed an increase in gulls on Taylor Pond.   The number of gulls counted on Taylor Pond ranged from 50 to a high of 3,000.  Typically he counted 800 gulls in the evening floating on the water this last summer.  He saw higher numbers during the migration of Herring Gulls in the fall.  When the ice covers the pond in the winter, most of the gulls leave the pond.  Some gulls remain and will roost at night out in the middle of the ice where they feel the safest.  Ben has observed flocks of gulls traveling down the AndroscogginRiver daily in the winter to roost in the ocean.  He speculates that they travel to the ocean because they feel safer roosting out on the ocean where they can easily spot approaching predators.  During the day, gulls fan out across the countryside to forage in farmer’s fields, open dumpsters and roadside trash.  In the summer, gulls gather over the pond in the evening, circling above looking for danger.  When they feel safe, they settle down in the middle of the pond to roost for the night.

We need to be concerned about the increase in gulls for two reasons.  First, their feces are loaded with bacteria which have the potential to make people sick when they swim or drink the water.  Reassuringly, two years ago, tests done on the water in Taylor Pond during the summer swimming season did not show any significant levels of bacteria.  Taylor Pond Association’s board recently made a decision to perform bacterial testing this coming summer to see if the increase in gulls will cause a problem.  Secondly, gull feces are high in nutrients, including phosphorous, which could cause an algal bloom.  However, ongoing testing for phosphorous levels in Taylor Pond demonstrated no increase from the gulls.  After learning about the potential problems that gulls can bring, we might be tempted to chase them off the lake to prevent problems from occurring.  Ben Nugent, who manages the gulls on LakeAuburn, reminds us that we cannot disturb wildlife without a permit and gulls are protected under the Migratory Bird Treaty Act.

Gulls provide entertainment for those of us watching the wildlife.  Year-round, one can often spot Ring-billed Gulls around the pond.  During migration many Herring Gulls appear and a few Great Black-backed Gulls show up throughout the year.  During a large mayfly hatch this past summer, large numbers of gulls swept through the air at dusk, feeding on the mayflies.  As it became dark, bats moved in and cleaned up what the gulls did not eat.  This winter Tim Priestly observed a Bald Eagle chasing down and devouring a gull on the ice in front of his home.  Charlie Todd of Maine Fish and Wildlife tells me that along the ocean shoreline gulls make up 50% of the Bald Eagles’ diet.  Fortunately, we have spotted many Bald Eagles year-round on Taylor Pond, perhaps they will keep the gulls from overwhelming the pond.

The Taylor Pond Association board will continue to monitor the gull situation and will review the data to be collected this summer regarding bacterial count.

Glossary of Lakeside Living Terms

by Anne Goorhuis 

As property owners living adjacent or close to the lake, we are all interested in maintaining a clean, algae-free Taylor Pond for our own enjoyment and to maintain the property values of our homes.  What follows is a glossary of must-know terms of the eco-speak of lakeside property care.

THE COMMON RAINDROP – The common raindrop is public enemy number one to maintaining water quality because of the following:  Rain carries soil down to the lake.  Soil binds with phosphorous and carries it to the lake.  High levels of phosphorous in a lake create algal blooms.  An algae bloom lowers property values and lessens our personal enjoyment of the lake.  See Erosion Control, Storm Water, Open Box Culverts, Phosphorous 

PHOSPHOROUS – The measurement of phosphorous is considered to be the most reliable measure of a pond’s capacity to have an algal bloom.  Thus any use of fertilizer (the most common way ponds get contaminated) should be judiciously weighed.  Test your soil via the Maine Extension Service, and amend only the recommended factors.   When reading a bag of fertilizer, such as 15 – 10 – 12, the middle number stands for Phosphorous.  Indiscriminate use of 20-20-20 fertilizer can be deadly to a lake!  If a soil test shows you need soil amendments, use slow-release products like bone meal, bloodmeal, or cottonseed meal.   Compost is the perfect amendment because it increases the soil’s capacity to hold water, yet keeps soil workable.  By the way, ponds with phosphorous levels below 15 are considered to be unlikely to have an algal bloom.  Taylor Pond’s mean (since 1975) is 11.  Kudos to us!  Let’s keep up the good work!

See The Common Raindrop, Storm Water, Erosion Control 

STORM WATER – Lengthy rains and down pours create storm water, i.e. precipitation that cannot be absorbed immediately by the soil.  How a property within a watershed handles storm water has a direct bearing on lake water quality.  Storm water that creates ruts in dirt roads only to be directed the shortest way possible to the lake carries loads of unwanted phosphorous into the lake.  Storm water that is diverted off the road into vegetated areas or catch basins, allows the soil to settle out and the water to filter before entering the lake.  Storm water coming off rooftops and driveways carries similar implications.  See Open Top Culverts, Level Lip Spreaders, Rain Gardens, Buffer Strips, Vegetated Buffers 

EROSION CONTROL – Erosion control methods allow storm water to be diverted to vegetated buffers or holding areas.  This cuts back on the quantity of soil displaced and keeps what has been displaced out of the lake.  The goal of erosion control is to allow storm water to be either spread out, filtered out, or absorbed.  All three goals keep the common raindrop from carrying phosphorous into the lake.   See Open Top Culverts, Level-lip Spreaders, Vegetated Buffers, Rain Gardens 

RAIN GARDENS – Rain gardens are natural or man-made depressions in the lawn area planted with attractive plants.  Water puddles here temporarily during times of rain.  To the lake, the advantage of a rain garden is that the roots of the plants absorb more water than mere grass.  To the homeowner, the advantage is more attractive landscaping surrounding the home.  Email the lake association if you would like a photocopy of example rain garden layouts.  See Erosion Control, The Common Raindrop 

OPEN TOP CULVERTS – Open top culverts are the opposite of a speed bump; they are dips in a dirt road that funnel storm water off the road into vegetated areas to be absorbed or filtered.  Normally constructed out of pressure treated wood, they are open at the top, and do require emptying once dirt settles into them.  This drawback is counterbalanced by the fact that open top culverts slow down the formation of unwanted ruts and potholes.  To view an open top culvert, travel West Shore Drive, Waterview Drive, Willard Road or the dirt portion of Taywood Road.  See Erosion Control 

LEVEL-LIP SPREADER – A level-lip spreader is essentially a catch basin with one important difference.  All rainwater flows down hill and some storms are so lengthy or intense that a ditch will fill up before a storm is over.  A level-lip spreader allows fast-running, soil-containing rain water to be diverted into it, creating a large, deep puddle.  Now that the water has slowed its speed, the dirt can settle to the bottom of the level-lip spreader, and cleaner water can flow out of it over a 6 foot to 12 foot lip (which is level) into a vegetated buffer and finally into the lake.  A wide band of slow flowing water is always preferable to a narrow band of quickly flowing water when it comes to lake water quality.  The water in the level-lip spreader is temporary, drying after a few days.  Knock on the door of 97 Taywood Rd. for a tour of the level-lip spreader on the author’s property.

VEGETATED BUFFER –  Ideally, the lakefront home will have three tiers of vegetation at the water’s edge;  mature trees, undergrowth of  younger trees or bushes and  the lowest level consisting of grasses, ground covers or low care perennials such as day lilies, hostas and sedum.   The more vegetation on the edge of the lake or near the end of an open top culvert the better, because vegetation encourages the absorption of water from the soil and the plants can use the phosphorous deposited there during times of storm water.  A “no-mow” policy is recommended for the first twenty feet of land along the length of the water’s edge, but an 8’ or 10’ buffer is also a great start.  This is also called a buffer strip.  On our property, when I decided to no longer mow at the water’s edge, I planted a row of low-care, long blooming day lilies to separate the “untidy” long grasses from the lawn chair area.  See Erosion Control, Level-lip Spreader, Open Top  Culvert, Phosphorous

NONPOINT SOURCE POLLUTION – To understand this term, consider the opposite:  If you can stand and point to a source of pollution such as a factory, farm or oil spill it is not nonpoint source pollution. Nonpoint source pollution is all the little stuff of modern living that does, in fact, add up and negatively affect the quality of our lake.  Examples include: rain coursing down our gutters and washing out the landing, the dirt churned up with rainwater in the ruts of dirt roads, home construction without the proper soil containment devices, the residual oil left in the lake from boat motors, the dust and tree dirt from our driveways.  These all have an effect. “Do we just stop living?” you may ask in frustration.  “No!” but we can choose to handle these minor sources of pollution as responsibly as possible.

Each property owner on or off the lake can allow the natural hollows in the lay of the land to remain, or create artificial ones via a rain garden.   Each property owner along a dirt road can choose to handle the storm water responsibly on his or her section.  Each lakefront owner can choose not to mow 8 feet next to the lake and to maintain their boats properly.  Knock on the door of 104 Terrace Rd. for a tour of how one homeowner manages the rain water off her section of dirt road.  

In conclusion, I hope some of you will hop in your car and tour some of the features mentioned above.  Or take some affirmative action, and sign up for the two hour LakeSmart presentation to educate yourself.  Lake living is worth an investment of time and effort!  Collectively a difference can be made!

Taylor Pond Good Habitat for Alewives

by Dana Little May 2007

In late summer, schools of alewives swarm by the shore; all moving in the same direction, thousands upon thousands of silvery fish about 2 inches in length. You can see them from afar, their silvery sides reflecting the sunlight.  The water appears to boil with them.  Pickerel and bass thrust into their midst, creating sudden swirls of water.  Kingfishers dive-bomb them from above; loons and mergansers swim to feed upon them.  Alewives grow to adulthood in the ocean far away but come home to Taylor Pond to breed.

Mike Brown of the Maine Department of Marine Resources has stocked Alewives in Taylor Pond since 1999.  This stocking program brings in about three-thousand fish into our pond every year.  In the spring, usually starting after the first week in May, the adult alewives head up the AndroscogginRiver from the ocean towards Taylor Pond.  They recognize the distinctive “scent” of Taylor Pond in the water pouring out of MerrymeetingBay at PophamBeach. They swim all the way up to the Brunswick Dam which stops them.  The Department or Marine Resources catches them at the Brunswick fish ladder and trucks them up to Taylor Pond.  Adult alewives are nearly a foot in length and over a half-pound in weight.  Mike unloads the fish into the pond to provide what he considers its carrying capacity of approximately 6 fish per acre.

The adult fish remain in the pond 3-4 weeks, laying eggs and feeding.  The adult fish return by way of Taylor Brook down to the AndroscogginRiver and back to the ocean.  The young hatch from the eggs and grow up to be the silvery fish that we see late in the summer.  They feed on the zooplankton (microscopic animals) that grow abundantly during the summer.  Mike samples the larval fish as they migrate down Taylor Brook during the summer and fall when they return to the ocean.  He will come 40-50 times during the summer to measure Taylor Pond’s production of alewives.  Mike considers Taylor Pond to be good habitat due to its shallow water, warm temperature and the small size of the pond.

Once the young fish return to the ocean, they feed and grow rapidly for the next 3-4 years.  Scientists call fish that live most of their lives in the ocean but that return to fresh water to breed anadromous.  Alewives share this trait with brown trout, Atlantic salmon and the American eel.  Locally, scientists consider the alewives to be the most abundant anadromous fish.  Historically, Native Americans and early European settlers highly valued them for food.  A variety of animals prey upon alewives including our resident bass, pickerel and pike.  In the ocean a variety of commercially harvested fish depend upon alewives as food.  In the 1970’s annual harvests of alewives in Maine exceeded 3 million pounds, more recently fisherman have harvested less than a million pounds.  Harvested alewives currently serve primarily as bait fish for lobster traps.  On our pond a variety of birds including loons, mergansers, kingfishers and herons enjoy the fish.  Otter and mink also can be seen feeding on fish.

The alewives’ highly developed olfactory sense, their sense of “smell”, tells them which river has Taylor Pond water mingled with it.  Thus each spring they choose to travel up the Androscoggin to return to Taylor Pond.  Someday we hope that these fish will once again be able to complete the entire journey independently.  For now, we depend on the Department of Marine Resources to maintain the population of this fantastic fish.  And the Department depends upon us to keep Taylor Pond a prime habitat for the fish.
