Reserve campsites at Willow River State Park.

Notice: The drawdown of Little Falls Lake is now complete. The dam was breached this fall in order to complete the full drawdown of the impoundment. The draw down is in response to safety issues identified with the dam structure.

The river will continue to flow through the lake bed throughout this process; however, the water will no longer be impounded to create the lake. This is a significant project, that is expected to last several years. While the lake is drawn down, the swimming beach will not be available but the sand area at the beach site is open for public use. Due to the receding water level, the boat launch is closed to trailer use. Canoe and kayak rental is not available. At this time, visitors may access the remaining impoundment by carrying in their own non-motorized boats.

The waterfall, camping and hiking trails are 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, see the Little Falls Dam information page.
