Your Guide to Fishing on the Upper Mississippi River in Wisconsin

Fishing in the Mississippi River offers year-round opportunities along the scenic bluffs and backwaters of Buffalo County. The Upper region near Fountain City and Alma provides access to diverse habitats, steady fish populations, and seasonal patterns that attract fishers from across the Midwest.

From spring walleye runs to winter ice fishing on the river, this stretch of river supports a wide range of fishing experiences.

The Upper Mississippi River

The Upper Mississippi River is known for its backwaters, side channels, islands, and main channel current. These natural features create ideal conditions for multiple fish species.

This section of the river is part of a large floodplain ecosystem. Water levels shift throughout the year, changing fish locations and patterns.

Fishing the Mississippi River waters means adapting to current, structure, and seasonal movement.

Fish Species

The upper portion of the river near Buffalo County supports diverse Mississippi River fish species. This mix of current and backwater habitats allows both cold and warm-water species to thrive.

Common fish species include:

• Walleye
• Sauger
• Smallmouth bass
• Largemouth bass
• Northern pike
• Bluegill
• Crappie
• Channel catfish

Some anglers also ask about dangerous fish in the Mississippi River. In this Wisconsin stretch, there are no commonly established aggressive species that pose a major threat. However, catfish have sharp spines and northern pike have strong teeth, so careful handling is important.

Upper Mississippi River National Wildlife and Fish Refuge

The Upper Mississippi River National Wildlife and Fish Refuge stretches across multiple states, including Wisconsin. It protects river habitat while allowing public recreation, including fishing.

The refuge includes backwaters, islands, wetlands, and forested shorelines. These habitats support healthy fish populations and migratory wildlife. Those fishing can access designated boat launches and shoreline areas throughout the region.

Fishing is permitted within refuge guidelines and state regulations. Visitors should review both refuge rules and Wisconsin fishing laws before heading out, such as those listed below.

Fishing Regulations

Anyone planning to fish the Mississippi River in Wisconsin waters must follow the state's fishing regulations set by the Wisconsin Department of Natural Resources.

Regulations include:

• Fishing license requirements
• Daily bag limits
• Size limits
• Seasonal restrictions

Rules may differ by species and location. The river is divided into pools, and regulations can vary from section to section. Always review the most current Wisconsin DNR regulations before your trip. 

Ice Fishing on the Mississippi River

Ice fishing on the Mississippi River is possible during winter when backwaters freeze. Main channel areas often remain open due to current, so anglers focus on calmer sections.

Common winter targets include walleye, perch, bluegill, and northern pike. Ice conditions change quickly depending on the weather and water flow. Always measure ice thickness and use proper safety equipment, as we wouldn't want you to fall through and literally sleep with the fishes.
