Bloom Forecast June 25 - July 2

Our models suggest that over the next week algae blooms are still likely, and that toxins are a possibility too. Probability of occurrence (%) of different algal concentrations (left) and whether a toxin will be present in the water (right) in the next week (note that the toxin predictions are still highly experimental).

Latest lake conditions

Water samples from the lake were analyzed last week for nutrients and algal concentrations. In addition, information on the weather was collected. These data are presented below as a percentage of their historical maximum.
Last sampled conditions at Detroit Lake, including the weather (temperature, wind, rain and sunlight) as well as the total concentration of algae (log transformed), nutrients (total phosphates and nitrates) and toxins (N/A denotes unavailable data).

Where we are in the season

It is June and historically this is the middle of the harmful algal bloom season. Number of algal blooms since 2013, for each month in the year.
