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.
