Forest Lake Alum Treatment Occurring September 25th - 29th

Project Description & Outcomes

This project involves multiple best management practices in order to reduce phosphorus loading to Moody Lake by a total of 62 pounds per year and reduce sediment loading by a total of 8,940 pounds per year. CLFLWD performed diagnostic monitoring and site-specific wetland coring to target remaining nutrient loading hotspots in the direct drainage area. Proposed projects include: agricultural field gully repair, excavation of phosphorus-laden soils, raingarden and other park improvements, and wetland dredging.

Watershed load reduction goals were identified as a result of the Moody Lake Diagnostic Study.

The CLFLWD received a $239,500 Clean Water Fund (CWF) grant from the Board of Water and Soil Resources (BWSR) for this project.
