Portage River, flowing through the scenic heart of Wisconsin, is a premier destination for anglers seeking diverse and exciting freshwater fishing adventures. Nestled within Portage County, this stretch of the Wisconsin River—often called the 'River In-Between'—features dramatic granite outcrops, rocky shorelines, and boulder-strewn channels that create ideal habitats for trophy fish. The river is especially renowned for its thriving smallmouth bass population, where aggressive fighters averaging 12-18 inches patrol the rocky structures, offering explosive topwater action.

Musky enthusiasts will find challenging and rewarding pursuits here, with the river and connected flowages like Lake DuBay harboring legitimate 50-inch giants. Walleye fishing peaks during spring runs below dams and along riprap banks, while the 'Catfish Corridor' delivers consistent channel cat opportunities. Beyond the main river, expansive backwaters and flowages like the Biron offer additional hotspots for crappie, bluegill, and northern pike, ensuring every angler finds their ideal challenge. With year-round guided trips available, Portage River promises unforgettable moments for both novice and seasoned fishermen amid Wisconsin's stunning natural landscapes.
