This report summarizes the findings of the 2025 water quality monitoring program for Taylor Pond in Auburn, Maine (MIDAS ID#3750).
Clarity readings and water quality measurements were conducted monthly from June through September by Woody Trask with additional clarity readings taken June into October by Michael Heskanen.
Since 2004, Taylor Pond Association has been collecting its own water samples and performing most tests. Phosphorus analyses are conducted by the DHHS Health and Environmental Testing Laboratory.
Result summary:
Whereas 2024 was a very good year number wise for Taylor Pond, 2025 was a pretty normal for all properties tested. Color and clarity values were average for the year in spite of having excellent values in September, the numbers most likely due to drought conditions resulting in little runoff into the pond. The highest clarity reading was 6.1 m, slightly lower than the high of 6.25m in 2024. The average of all clarity readings was 5.0m which is 0.65m lower than last year’s average reading but higher than the historic average of 4.76m. On average, the water had more coloration than 2024 with an average color value of 25 versus 2024’s value of 18.75. 2025 experienced few rain events which created drought conditions resulting in the lowest water level experienced in recent memory.
The average 5 meter core sample phosphorus reading of 10.25ppb was slightly lower/better than last year’s average but slightly higher than the historic average. The average 12 meter bottom phosphorus reading of 31.75ppb was quite a bit higher than in 2024 and higher than the historic average. This could be due to less dilution due to low water conditions.
Values for pH and alkalinity where all within the normal range of variation from the historic mean. The conductivity was higher than both last year’s reading and the historical average.
The average surface temperature taken at 1 meter depth was 23.6oC (74.5°F), which is 1.2°C (2.6°F) cooler than last year’s record high and only 0.4°C (0.7°F) higher than the average for the past 16 years.
There were no algal blooms reported in 2025.
“Ice-in” occurred on December 23, 2024. The “ice-out” date was April 13, 2025, which happens to be the historical average going back to 1969, giving a fairly average “ice cover” period of 111 days. Longer periods of ice cover are considered beneficial to the health of ponds
