The WSIP includes seven projects that would boost California’s water storage capacity by 2.77 million acre-feet. The projects range from expanding existing reservoirs to increasing groundwater storage to building 21st century surface storage facilities. Each project’s timeline to construction and operation may be different, but they all must submit the Proposition 1 statutory requirements, which include final permits, completed environmental documents, contracts for the administration of public benefits, and contracts for non-program funding – before returning to the Commission for a final award hearing.
Harvest Water Program Awarded Prop 1 Funds
In June 2023, the Commission awarded the Harvest Water Program $277.5 million in Proposition 1 funding. The conjunctive-use project will supply up to 50,000 acre-feet of treated wastewater for irrigation in south Sacramento County. Public benefits of the project include increased streamflow volume in the Cosumnes River, extended migration window for fall-run Chinook salmon, reduced salinity load to the Sacramento River and Delta waterways, improved groundwater conditions for 5,000 acres of wetland and riparian forest, and enlarged habitat for sandhill crane and many other threatened and endangered species.
WSIP Early Funding
WSIP regulations allow for a portion of the Commission’s maximum conditional eligibility determination (MCED) to be awarded before the final funding hearing to assist with permits and environmental documents. Early funding cannot exceed 5% of a project’s MCED. In all, the Commission has awarded six projects early funding totaling $123.4 million. Early funding amounts: Chino Basin Program - $10,763,270. Harvest Water Program - $14,375,625. Los Vaqueros Reservoir Expansion Project - $23,877,917. Pacheco Reservoir Expansion Project - $24,200,000. Sites Project - $43,769,818. Willow Springs Water Bank - $6,413,744.
