Lake Cornelia Water Quality Improvement Project–postponed until spring 2020

To improve the health of Lake Cornelia, the District will conduct an alum treatment. Because the alum is not effective when water temperatures fall below 45 degrees F, the treatment will take place in spring of 2020. The District and HAB Aquatic Solutions will also have a demo presentation in spring to explain the alum treatment process to those interested.
