Notice: A complete drawdown of Little Falls Lake is scheduled to begin June 1st (flooding and weather dependent) to complete an inspection and repairs to Little Falls Dam. This is a significant repair project and the drawdown is expected to last several years. While the lake is drawn down the swimming beach, boat launch and canoe and kayak rental will be closed. The waterfall, camping and hiking trails will 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.
