The river drops and turns right, pushing boats towards a rock on the left. At high water there is plenty of room to maneuver. Rock Dam at mile 39.5 should be scouted on the right. A small gully enters the river on the left just above it, and part of an old concrete diversion dam is visible on the right. The noise of the rapids at the broken dam alerts you to its presence.
Possible routes are on the left or in the center at high water.
At low water rafters may choose to line this rapids on the right. Lake Owyhee is the toughest run on this section. It is an 8-mile long stretch. In light rafts without a headwind, expect a minimum of four hours to cross it. Contact the River Forecast Center in Portland for the flow at Rome.
