Restoring Water Quality with Alum Applications In Minnesota Lake
Bald Eagle Lake is 1,071 acres in size and is located just north of the Twin Cities near the town of White Bear Lake, MN. The Rice Creek Watershed District partnered with Wenck Associates to complete a Total Maximum Daily Load (TMDL) study and determined Bald Eagle Lake’s water quality was impaired and threatened by an excess of phosphorus.
Implementing Alum As A Water Quality Restoration Tool
The watershed district contracted with SOLitude Lake Management to conduct two liquid alum applications. In April 2014, half of the required dose was applied (248,000 gallons) in 8 days. The remaining dose (an additional 248,000 gallons) was applied in April 2016.
