Middle Iowa Watershed
The Middle Iowa Watershed Management Authority (MIWMA) formed in June 2023, and is a group of cities, counties, and Soil and Water Conservation Districts (SWCDs) working together toward watershed improvements, with focus on improving water quality and habitat, and reducing risk from floods. There are currently 15 members but the authority is open to new members as the watershed overlaps jurisdictional boundaries of 10 counties, 34 cities, and 10 SWCDs.
Many partners and stakeholders are active with the MIWMA, including both state and federal organizations, non-profits, and unincorporated communities. A complete list of eligible and member cities and counties is provided in the official MIWMA 28E Agreement, which is maintained on the Iowa DNR web site.
