The Target North St. Paul Stormwater Retrofit project will target phosphorus removal from stormwater runoff. This runoff receives limited treatment before discharging to Kohlman Creek, a waterbody impaired for excess nutrients. This project is one of many efforts RWMWD has undertaken to improve the water quality of Kohlman Lake and the downstream waterbodies. The Ramsey-Washington Metro Watershed District (RWMWD) is responsible for the protection and restoration of the water quality of 20 lakes and 5 creeks within its boundary.
Installation of approximately 25 curb-cut rain gardens in priority subwatersheds. Ramsey County Soil and Water Conservation Division has completed 90% designs and are incorporating final design modifications based on comments from our partner Cities (St. Paul and Roseville). Three rain gardens are proposed in the McCarrons subwatershed and 23 are proposed in the Como Lake subwatershed.
Rice Creek WD proposes completion of three projects during this WBIF cycle: 1) Clearwater Creek Stabilization Scoping: The portion of the Main Trunk of Anoka Washington Judicial Ditch 3 (AWJD3, also known as Clearwater Creek) downstream of I-35E has a steep grade with heavily scoured and sloughing banks due to high peak flows and channel velocities and unstable sandy soils.
Implementation of Vadnais Lake Area WMO (VLAWMO)'s existing Landscape Level 2 Grant Program to install at least 1 BMP project between 2023-2025 to make progress on water quality impairments within four priority subwatersheds: Lambert Creek, Goose, Birch, and Gilfillan-Tamarack-Black-Wilkinson-Amelia. Eligible BMPs include project types identified in the Board-approved Landscape Level 2 Grant Policy. The anticipated outcome is a reduction in phosphorus by at least 0.3 pounds annually. This activity will also result in strengthened partnerships with Vadnais Lake Area WPA communities.
