• Pine Lake had very clear water, with low to moderate nutrient concentrations and low to moderate algal growth.
• Long-term trends suggest that water quality in Pine Lake has been improving over time, with decreasing nitrogen and chlorophyll concentration sand deeper Secchi (clearer water) depths.
• An algal bloom was sampled for toxin testing in April and September. No algal toxins were detected in this sample.

This bathymetric map shows contour lines of equal depth, similar to a topographic map would for mountains and valleys. The red 'X' marks the location where water quality samples are taken.
This map shows the area of the watershed relative to the area of the lake. Generally speaking, the larger a watershed is relative to a lake, the greater the influence land use practices on lake water quality.
The average of these three TSI indicators during the growing season can be used
to place lakes in one of three broad categories:
<40 = oligotrophic (low productivity),
40 to 50 = mesotrophic (moderate productivity)
>50 = eutrophic (highly productive).
