Document Description
Orr Creek Reservoir is located just north of the city of Auburn, Placer County, CA, on District-owned property (approx 30 acres). Since the Orr Creek Dam was constructed, silt and sediment have deposited in the reservoir, resulting in a significant reduction in its water storage capacity from the designed 27 acre-ft to an estimated current capacity of 3-4 acre feet. The District proposes to a) remove an estimated 10,000 cubic yards of accumulated sediment from the reservoir and restore a portion of its original 27 acre-ft of storage capacity; b) repair and improve the dam infrastructure including repairing cracks that have formed in the concrete dam structure; c) replace and realign the diversion pipe to the Gold Hill I Canal to increase efficiency and improve access for the District personnel; and d) add a low-level outlet at the base of the dam through which water could be released downstream into Orr Creek to maintain the storage capacity of the dam and improve downstream aquatic habitats. Therefore, the purpose of the project is to improve the efficiency of the District's raw water delivery systems by restoring the storage capacity of the reservoir and improving the reliability and safety of the associated dam and water delivery infrastructure.
