Reserve campsites at Willow River State Park.

Notice: A draw down of Little Falls Lake is being evaluated in order to complete an inspection and any identified repairs needed to Little Falls Dam. This is a significant project and the drawdown would be expected to last several years. While the lake is drawn down the swimming beach, boat launch and canoe and kayak rental would be closed. The waterfall, camping and hiking trails would be unaffected by this project.

If you would like updates on this and other happenings at the park, you can sign up to receive news from Willow River State Park.

For more detailed information about the drawdown and dam repair, see the Little Falls Dam repair information page.
