The St. Croix River from Taylor's Falls downstream to the confluence with the Mississippi River contains Grass Carp, Silver Carp and Bighead Carp. Report any catches of these fish to the Minnesota DNR.



Fishing on Lake St. Croix is often limited by extremely high level of recreational boating. Angling for Walleye and Sauger is the most popular fishing activity on this lake. There has been increased interest in Muskie angling in recent years. White Bass and Crappie populations tend to fluctuate greatly.
