A state designated wild river, the Popple is a river of contrasts as it flows through the Nicolet National Forest. Long stretches of still waters are interrupted by short, exciting rapids. Best water levels occur in the spring and early summer. The Red Cedar runs 60 miles from Chetek to the Chippewa River below Menomonie. The lower 15 miles parallel the Red Cedar State Bike Trail.
Fishing is good all along the river.
Access is available at numerous county parks. Canoe rentals are offered at many towns along the river.

The Rock River begins in the famous Horicon Marsh and flows through both Lakes Sinissippi and Koshkonong on its way to the Mississippi River.
