Notice: Little Falls Lake has been drawn down in response to safety issues identified with the previous dam structure. The river will continue to flow through the lake bed throughout this process; however, the water is no longer impounded to create the lake.
The dam has been approved to be replaced, but this is a significant project that is expected to last several years. For the summer of 2016, the swimming beach will not be available but the sand area at the beach site is open for public use. Due to the low water level, the boat launch is closed to trailer use. Canoe and kayak rental is not available. 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.
