• Lake Killarney to have fairly clear water, moderate nutrient concentrations and high algal growth. • Long-term trends suggest that water quality in Lake Killarney has been improving over time, with decreasing nitrogen and phosphorus concentrations. • Nitrogen-to-phosphorus (N:P) ratios were below 25 for the majority of the monitoring season. This indicates the potential for algal blooms to be dominated by cyanobacteria (which have the ability to produce toxins). • No algal blooms were reported for toxin testing in 2020.

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).
