Webster Lake was monitored in 1996 and 1997 and then resumed in 2020. The key takeaways from the 2020 monitoring season are:
• Further monitoring is needed to identify any long-term trends. • Webster Lake had fairly clear water, with moderate nutrient concentrations and algal growth. • No algal blooms were reported for toxin testing in 2020.
Historic profile data indicated that thermal stratification might be somewhat unstable through summer, but the sediments do release phosphorus into the deep water. Nitrogen to phosphorus ratios were generally below 20:1 late in the summer, which favors bluegreens over other species of algae.

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).
