Wisconsin River Fishing Guides and Conditions, Wisconsin

About the Wisconsin River

Below the last dam at Prairie du Sac the Wisconsin River runs ninety-two miles to the Mississippi without another impoundment, through a corridor of sandbars, wooded islands and bluffs protected as the Lower Wisconsin State Riverway. It is the longest free-flowing stretch of river in the Midwest and it is a genuinely different kind of fishing trip: shallow, sandy, braided water where you read sandbar edges and wing dams instead of rocks.

Smallmouth bass are the main quarry and the river holds them in numbers, along with walleye that stack below the Prairie du Sac dam in spring, a good musky population, channel and flathead catfish that reach serious size, and a native lake sturgeon run. Most guided days are run in jet boats or shallow-draft boats because the sandbars move constantly and a prop is a liability. Canoe and kayak trips with sandbar camping are the other tradition here, and it is one of the best multi-day paddle trips in the Midwest.

The Muscoda gauge reads a very large basin. Summer flows in the low thousands of cfs give normal sandbar conditions; spring flows several times higher cover the bars, move the channels and change the river’s shape for the season. Because the bed is sand, the navigable channel genuinely relocates from year to year, which is why local knowledge matters more here than on a rock-bottom river.

Sauk City, Spring Green, Muscoda, Boscobel and Prairie du Chien line the corridor. Spring Green is the best-known base, and the whole valley is easy driving from Madison.

Access

Prairie du Sac and Sauk City: the top of the free-flowing river below the dam, prime spring walleye water.
Arena and Mazomanie: upper riverway landings.
Spring Green and Peck's Landing: mid-river access and the busiest recreation stretch.
Lone Rock and Muscoda: landings near the gauge.
Boscobel and Woodman: lower river ramps.
Bridgeport and Wyalusing State Park: the Mississippi confluence at the bottom of the riverway.

Seasons

March through May: walleye below the Prairie du Sac dam, high water and moving sand.
June through August: prime smallmouth and catfish, sandbar camping, low clear water by August.
September and October: the best smallmouth month, cooling water, few boats.
November through February: musky and walleye until ice; the river freezes in most winters.
