Robles Diversion and Fish Passage Facility
Document Description
The primary objective of the Casitas routine maintenance and repair program is to ensure the proper operation of the Facility. By maintaining the Facility consistent with its original design, Casitas reduces or prevents ineffective operation of the water diversion and fish ladder. The Facility allows a portion of Ventura River flows to be diverted into the Robles Canal, which transports the water to Lake Casitas for storage and ultimately municipal and agricultural use. Casitas provides drinking water for approximately 70,000 western Ventura County residents (City of Ventura, City of Ojai and unincorporated Ventura County areas). Additionally, Casitas provides irrigation water for roughly 5,000 acres of mostly permanent agricultural crops. Lake Casitas is the only reservoir from which Casitas supplies its customers, and adequate lake levels are dependent on receiving sufficient inflows from the Robles Canal. The proposed maintenance and repair activities preserve the conveyance capacity of the Facility by preventing the accumulation of obstructing vegetation and sediments that could impede Facility fish passage and water diversion operations.
