About Prairie River
The Prairie River in Lincoln County, central Wisconsin, is a productive medium-sized trout stream with wild brown trout and brook trout in the cold headwaters. The river flows through a mix of state forest and private land with strong public-access easements. A reliable central-WI alternative when the Driftless and northern rivers are pressured or off-color.
Regulations
Wisconsin Fishing License required ($20 resident + $10 trout/salmon stamp = $30). Season opens first Saturday in May. Verify Lincoln County special-regulation sections in current Wisconsin DNR trout regulations.
