Clear Lake Water Quality Project

City of Forest Lake, Minnesota

Under tight deadlines, Bolton & Menk presented a new design concept to increase pollutant removal through an innovative treatment train approach with multiple uses of iron enhanced sand filtration technology. A flow diversion channel, rock gabion weir with iron enhanced sand filtration core, bioretention floodplain, and perched iron enhanced sand filter maximized the opportunity for runoff treatment. A total phosphorus reduction goal of 140 pounds per year was established, with the project providing more than 70 percent of that goal.

This project has become the gold standard for how the city intends to manage stormwater. Investing in these innovative projects will continue to protect valuable water resources, reduce further degradation of the nearly-impaired resources, and eliminate the need for lengthy and costly lake restoration projects in the future.
