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.
Webster Lake has no public access boat launch. Lake users should keep a close eye on aquatic plants growing nearshore to catch infestations of Eurasian milfoil, Brazilian elodea or other aquatic noxious weeds.
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).
