fishing. The average size of browns runs between 10-14 inches, with some fish reaching 18-20 inches. Because of limited access, fishing pressure on the lower river varies. Along private stretches, the river is rarely fished. Most of the angling is done at the few state access sites below the dam. This can cause significant crowding along those stretches, especially during the summer months.
Seyler Lane access litigation

Landowner James Cox Kennedy who had recently purchased the property was denying access to recreationalists via the Seyler Lane bridge. The litigation was finally resolved in 2014 when the Montana Supreme Court
