About Tomorrow River

The Tomorrow River in Portage County, central Wisconsin, is a classic medium-sized trout stream with wild brown trout and brook trout in the cold spring-fed headwaters. The river flows through a mix of forest and farmland with extensive public-access easements. A reliable choice when the Driftless rivers are crowded or blown out by spring storms.
