Bloom Forecast Apr 29 - May 6

Our models suggest that in the next week there is a strong chance that algae will become abundant, and that toxins may occur. 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 concentration of algae, nutrients (total phosphates and nitrates) and toxins (N/A denotes unavailable data).

Where we are in the season

It is April and historically there have been very few algal blooms this month, although the season could start early. Number of algal blooms since 2013, for each month in the year.
