Click on a sampling location on the map to view its data below. Data points labeled as "Non-Detectable" indicate a Microcystin sample that measured less than 0.1 μg/L.

We also have included data collected on Chlorophyll a concentrations, water temperature sampled from a CTD (conductivity, temperature, and depth) profiler, and secchi depth.

For 2018, samples were taken at the surface (approximately 0.75 m deep) and bottom (1 m off the bottom of the lake).

WHO Recommended Guidelines (for reference)

Particulate and Dissolved Microcystins have different vertical axis ranges
