Willow River State Park Current conditions

Little Falls Lake: The lake has been drawn down due to safety issues with the previous dam. The river will continue to flow through the lake bed, 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 more information, see the Little Falls Dam web page.


Ski trails are open and are designated for skiing only. Please no pets on ski trails. Ski trail conditions [exit DNR]. There are about 5 miles of hiking/snowshoeing trails also available in the winter. The hiking/snowshoeing trails are also open for pets on leash.

Camping and facilities

All waters systems and buildings are shut down for the season. Vault toilets are available in each campground and throughout the park. The sanitary dump station is closed for the season. Drinking water is available at the park’s maintenance shop. Walk-in or ski-in camping is available in the 200 campground only. The sites are not plowed and there is no vehicle access. All of the other campgrounds are closed for the season.

Camping reservations for outdoor campsites can be made online or by calling 888-947-2757.


The draw down of Little Falls Lake was completed in October 2015 to complete necessary work on Little Falls Dam. This project is expected to take several years. The river will continue to flow through the lake bed, however the water is no longer impounded to create the lake. Access is still allowed, though much of the shoreline is extremely soft and muddy.

The U.S. Geological Survey river level gauge website reports water levels and flow.


Wildlife has been abundant. Pheasants, deer and waterfowl can be seen throughout the park. There are many swans and other waterfowl that winter in the open waters of the Willow River.
