Bald Eagle Alum Application

Regular water quality testing has occurred on Bald Eagle since 1980.  In 2002, the lake was placed on the State’s Impaired Waters List for phosphorous, and chlorophyll-a, a measure of algae in the water.  Severe algae blooms were common. In 2014, the RCWD worked with HAB Aquatic Solutions to apply the first alum treatment to Bald Eagle Lake.  The project resulted in immediate gains in water clarity with visibility reaching almost 7 feet on average.  Following the first alum treatment, Bald Eagle Lake has met state standards for first time in more than three decades.

After the first of the two treatments in 2014, the lake met state water quality standards for the first time in three decades.
