Water Quality Trends
Long-term Secchi Disk Transparency (SDT), total phosphorus (TP), and
Chlorophyll-a data are used to determine if the trophic state of a lake
may be changing. Long-term trends may be calculated if there are at
least 10 years of data collected within the last 30 years (1993-2022).
If there are at least eight years of data within the most recent 10
years, a recent trend test may be calculated as well. The results of
trend tests are presented here if there have been enough data
collected from Taylor Pond for any of these three parameters.
The Maine Department of Environmental Protection uses Mann-Kendall Tau
(τ) trend tests on these data to test for significantly changing
conditions. The tau value is a measure of trend direction and magnitude.
Positive tau values indicate positive (upward) trends, negative tau
values indicate negative (downward) trends. Values further from zero
(closer to -1 or 1) indicate a stronger trend. Tau values less than -0.5
or more than 0.5 here suggest the trophic state of a lake may be
changing. Trends with p-values less than 0.05 indicate statistically
significant trends.
