Project Description & Outcomes

This project will treat 50% of this subwatershed’s runoff with a multi-cell iron enhanced sand filtration (IESF) treatment system. The headwaters of Washington Judicial Ditch 6 (WJD-6) is dominated by wetlands and contributes nearly half of the total phosphorus load in the WJD-6 system, most of which is dissolved and difficult to remove with traditional best management practices (BMPs). This IESF will reduce watershed phosphorus loads to Forest Lake by 97 lb/yr.

This project, among other recommended projects, was identified as a result of the Forest Lake Diagnostic Study and WJD-6 Assessment and Feasibility Study (Phase 1 | Phase 2).

The CLFLWD received a $747,400 Clean Water Fund (CWF) grant and a $191,965 Section 319 Small Watershed Focus grant for this project.
