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 2017, samples are taken at up to 4 depths with respect to their sampling location's column depth: surface scum, surface, bottom for sites WE 2 thru 13, and for WE13, mid-column. Surface scum covers the very top of the column, surface is approximately 0.75 m deep, bottom is 1 m off the bottom of the lake, and mid-column is half-way between the surface and bottom measurement's depths. These depths are represented in columns of charts below.
WHO Recommended Guidelines (for reference)
Drinking water = 1µg/L
Low risk recreational = 2-4µg/L
Moderate risk recreational - 20µg/L
High risk recreational = avoid visible scums
Please note that the surface scum Chl A. and Particulate Microcystins vertical axes have greater ranges than the other depths.
Particulate and Dissolved Microcystins have different vertical axis ranges
