Has the Wisconsin Department of Natural Resources conducted any monitoring for blue-green algae?
The WI DNR conducted a two-year study to investigate the frequency, severity, and duration of blue-green algae blooms, including information on which species of blue-green algae are present over the course of the summer. We also looked for the presence and concentrations of specific toxins: anatoxin-a (a neurotoxin), microcystin-LR (a hepatotoxin), and cylindrospermopsin (a cytotoxin). Samples were (for the most part) collected from five lakes in each of five regions, five times over the course of each summer (2004 and 2005). Samples were also collected from eight ponds in the south central region of the State. It is important to note that we chose to sample sites where blue-green algae blooms had occurred in the past or where they could potentially occur, based on nutrient concentrations. Therefore, this was not a random sample of lakes and ponds meant to represent all lakes and ponds in Wisconsin.
