Trophic and Water Chemistry Data

**Table Legend:**

**Color**: Color (SPU), **Alk**: Alkalinity (mg/l CaCO₃), **SpCon**: Specific Conductivity ( $\mu$ S/cm), pH: pH (standard units)

TP = Total Phosphorus ( $\mu$ g/L) – EC: Epilimnion Core, SG: Surface Grab, BG: Bottom Grab, PG: Profile Grab

**SDT** = Secchi Disk Transparency (m) – **Min**: minimum value, **Avg**: average value, **Max**: maximum value, n: number of months with Secchi readings per year, b: number of times Secchi disk was observed touching the bottom of the lake per year

**Chl** = Chlorophyll-a ( $\mu$ g/L) – **Min**: minimum value, **Avg**: average value, **Max**: maximum value

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 Little Squaw 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.
