• Prior to 2022, Lake Leota was last monitored in the Lake Stewardship Program from 1998-2009. Further monitoring is needed to identify any long-term trends.
• Lake Leota had fairly clear water, with moderate nutrient concentrations and low algal growth.
• An algal bloom was sampled for toxin testing in August. Toxin testing found very low concentrations of algal toxins, well below the Washington State Recreational Guidelines.
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).
