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. For current ski trail conditions go to: There are approximately 5 miles of hiking/snow-shoeing trails also available in the winter. The hiking/snow-shoeing trails are also open for pets on leash.


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.

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


Wildlife has been abundant. Pheasants, deer, turkeys, and waterfowl can be seen throughout the park. There have been numerous owl sightings and many migratory birds are showing up in the park.


See the DNR events calendar for a list of upcoming events at Willow River State Park.

If the office is closed when you arrive, please self-register for vehicle admission stickers as needed outside the office. Campers must register or check-in at the office during office hours. Complete instructions and fees are posted above the wooden box and inside the bulletin board. Annual stickers bought via self-registration may be picked up at the office the same day if the office is open; annual stickers and any change due will be mailed promptly.

Professional photographers are reminded that they need a Commercial Use Permit to shoot for hire in the park by a client, as does anyone else bringing in a client for activity in the park (fishing guide, personal fitness trainer, etc.). Please check with the park office for more information.
