Moody Lake Coverage Map

HAB has downloaded and processed the buffered alum application data from the barge’s guidance and dose control computer system.  The dose rate coverage map shows each individual application path that were recorded over the course of the Moody Lake application.  We are extremely pleased with the precise application and uniform coverage of the 17-acre application…

Before & After

The first photo of the cyanobacteria (blue-green algae) bloom was taken at Moody Lake the afternoon before the buffer alum application was conducted.  The second photo, showing the clearer water, was taken at the same location on the morning after the application.  This dramatic and immediate change is a result of the alum floc removing…

Project Complete!

How Does an Alum Application Affect Fish and Plants?

Aluminum is considered a non-essential metal because fish and other aquatic life do not need it to function. There is a large body of scientific literature documenting the safe use of alum in lake environment conditions, which has allowed the North American
Lake Management Society to fully endorse its use (NALMS, 2017).
