Phoenix Lake Restoration and Preservation Project
Request for Proposals for Construction Management Services

Phoenix Lake Reservoir is an 88‐acre water storage reservoir located near Sonora, California. The reservoir is primarily used as a drinking water source for the communities of Sonora, Jamestown, Scenic View, and Mono Village. The reservoir also serves as a fill source for California Department of Forestry and Fire Protection (CAL FIRE) helicopter operations, is a scenic and ecologically important aquatic habitat, and is used for non‐motorized, non‐contact recreation by the communities surrounding the reservoir.

Since construction, the reservoir’s water storage capacity has decreased substantially due to sedimentation. While the storage capacity of the reservoir is 850 acre‐feet (ac‐ft), the current capacity is only 600 ac‐ft. Reduced reservoir capacity affects the water quality at Phoenix Lake, which is marginal at times and is declining due to nutrient inputs, sedimentation, and proliferation of exotic invasive aquatic vegetation. The District was awarded funding through Integrated Regional Water Management (IRWM) grant from the California Department of Water Resources (DWR) to remove sediment from the reservoir. The primary goals of the proposed project are to restore drinking water storage capacity, improve water quality, and enhance wetland functions.

Implementation of the proposed project would increase the water supply reliability and improve water quality for the Districts largest water system, serving more than 10,000 customers, as well as commercial and agricultural users.
