Monitoring Agencies
Ozaukee County, Wisconsin Department of Natural Resources (WDNR), United States Fish and Wildlife Service (USFWS) and several volunteers conduct fisheries monitoring on an annual basis throughout the Milwaukee River Watershed. These surveys typically occur in the late spring and summer and consist of electrofishing by boat mounted, backpack or tow-behind barge units.

All 3 agencies have partnered to tag and clip fish to help track seasonal spawning runs and other movement patterns throughout the Milwaukee River and tributary streams.
Over 500 fish have been tagged or marked during fish surveys near the fishway. Recaptures of tagged or marked fish are documented in future surveys, reported by local anglers or detected by the underwater camera and Passive Integrated Transponder (PIT) tag readers in the fishway exit, view more information on the camera and tag readers.
Finding Tagged Fish
If you come across a tagged or finclipped fish, you are encouraged to contact the Fish Passage Program or your local WDNR fisheries biologist. Check out the Fish Passage Program on Facebook for more fish pictures from the Milwaukee River Watershed!
