Kayaking opportunities are still available in the river, however kayakers should be aware of changing river conditions and underwater debris. Please avoid the construction area around the dam. Other area lakes and the St. Croix River offer motorized boating opportunities.

Fishing
Fishing is primarily limited to the river due to the drawdown of the lake. Some warm water species such as panfish, bass and northern can be found below the dam. The Willow River is stocked with trout and fishing is available both above and below the lake bed. Trout fishing is likely best upstream of the waterfall.
