Washington Judicial Ditch-6 Wetland Restoration

Project Description & Outcomes

The purpose of this project was to reduce the amount of phosphorus entering Forest Lake via Washington Judicial Ditch-6 (WJD-6).

The project restored a wetland along WJD-6 by excavating phosphorus rich sediment and restoring native vegetation. This created deeper pools of water and shallow wetland benches that allowed the wetland to naturally remove phosphorus and suspended soil from the water. The restored native vegetation also provides habitat for wildlife.

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

The CLFLWD received a $386,000 Clean Water Fund (CWF) grant from the Board of Water and Soil Resources (BWSR) for this project.
