Prior to HAB’s aluminum sulfate treatment the 30 year water clarity summer average was 1.2 meters at Bald Eagle Lake. Post alum lake treatment, water quality has been averaging 2.5 meters as collected by the Rice Creek Watershed District.
Bald Eagle Lake is 1071 acres in size located in Minnesota just north of the Twin Cities near the town of White Bear Lake. The Rice Creek Watershed District partnering with Wenk Engineering completed a Total Maximum Daily Load (TMDL) study to determine Bald Eagle Lake was impaired, or threatened, by an excess of phosphorus. The watershed district contracted with HAB Aquatic Solutions to assist in the lake restoration. In spring 2014, one-half of the dose required to treat the lake was applied. The remainder will be applied in the spring of 2016.
