WATERSHED-BASED PLAN
- Draft 2022 North Branch Chicago River Watershed-Based Plan Update
Lake County Stormwater Management Commission (SMC) updated the 2008 Watershed-Based Plan for the North Branch Chicago River watershed. Projects that improve water quality and are identified in watershed-based plans are eligible for grant funding through the Clean Water Act. SMC led development of the North Branch Chicago River Watershed-Based Plan in 2008 and this 10-year update maintains consistency with Illinois EPA and Clean Water Act guidance.In February 2022, Lake County Stormwater Management Commission submitted a draft of the North Branch Chicago River Watershed-Based Plan to the Illinois EPA for their review and comments. Funding for this project is provided, in part, by the Illinois Environmental Protection Agency through Section 319 of the Clean Water Act.
