State or Federal?
In November 2014, California voters approved Proposition 1, the Water Quality, Supply, and Infrastructure Improvement Act of 2014. Chapter 8 of Proposition 1 provides $2.7 billion for public benefits associated with water storage projects that improve the operation of the state water system, are cost effective, and provide a net improvement in ecosystem and water quality conditions.

The California Water Commission has identified ecosystem priorities within two main categories: flow and water quality, and physical processes and habitat. See the WSIP regulations for further details. Eligible project types include surface storage projects, groundwater storage, groundwater contamination prevention or remediation with storage benefits, conjunctive use, reservoir reoperation, local surface storage, and regional surface storage.
