Wisconsin Public Service owns and operates the Grandfather Falls hydroelectric project that includes a license condition to provide a whitewater boating opportunity. Flows are between 1500 and 1800 cfs.
The Grandfather Falls bypass reach extends approximately 4,500 feet downstream of the dam to the powerhouse tailrace. The terrain is irregular and rugged, characterized by large boulders and bedrock outcrops interspersed with cobble.
