The Saint Croix River is a premier fishing destination flowing along the border between Minnesota and Wisconsin. This National Wild and Scenic Riverway offers diverse fishing environments across its 165-mile length, from the headwaters at Upper St. Croix Lake in northwestern Wisconsin to its confluence with the Mississippi River at Prescott, WI. The river features exceptional water quality, varied underwater habitats, and supports over 60 documented fish species, making it one of the most biologically diverse rivers in the Upper Mississippi River Basin. With stretches ranging from boulder-strewn rapids to deep, calm pools, the Saint Croix provides outstanding fishing opportunities for anglers of all skill levels throughout the year.
