• Beaver Lake 2 had fairly clear water, with low nutrient concentrations and moderate algal growth.
• Beaver Lake 2 has contrasting trends in nitrogen and phosphorus concentrations, which is not common. Nitrogen concentrations have decreased over time, while phosphorus concentrations have increased.
• An algal bloom was sampled for toxin testing in August. No algal toxins were detected in the sample.
• Investigate potential sources of phosphorus that could be leading to the increasing trend.
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).
