Red Bluff Diversion Dam Fishway Attraction Study. Spillway Operation Test
Red Buff Diversion Dam was constructed in the mid 1960's. The dam spans the Sacramento River with eleven 60-ft wide spillway gates. Plan and sections of Red Bluff Diversion Dam and stilling basin are presented. All spillway gates can be operated in automatic mode using an upstream lake elevation target. However, typical operation of the spillway gates has gates one through ten manually changed in response to large changes in river glow. Gate 22 operates in auto mode to regulate the upstream water surface for gravity diversion to the Tehama Colusa Canal. Downstream of gates one through ten is a Type II hydraulic jump stilling basin with a concrete apron and solid endsill. Downstream of gate 11 is a Type III hydraulic jump stilling basin. Both stilling basins have experienced significant abrasion damage over the past 40 years. Damage has occurred primarily near the basin chute blocks and endsill. The designer's Operating Criteria (DOC) for spillway gate operation was revised in 1970 to address the problem of concrete abrasion in the stilling basins. The criteria places two constraints on spillway operation.
