Several sites in the Ulao Creek watershed near Grafton in Ozaukee County, WI

Ozaukee County is remediating as many as six impediments to fish passage in the West Branch Ulao Creek. This project is working to reconnect half a mile of stream for northern pike and other fish within the Milwaukee Estuary Area of Concern. The Ulao Creek watershed was historically known for sizable spawning runs of northern pike. Currently, migrations in West Branch Ulao Creek are restricted and/or prevented by known structural and non-structural impediments, and the creek is unlikely to support regular spawning runs for most migratory fish species. Project activities will complement ongoing and completed connectivity projects downstream by removing multiple identified fish passage impediments and reconnecting approximately 0.5 stream miles, 11 acres of wetland habitat and 16 acres of floodplain habitat to the mainstem Milwaukee River, the Milwaukee Estuary AOC, and Lake Michigan. Overall project goals and objectives include restoration of aquatic life access to existing high quality spawning and rearing habitat, improvement of recruitment from existing high quality habitats, and demonstration of successful utilization of the stream through active fisheries monitoring.
