Bay Delta Plan

The State Water Resource Control Board is a regulatory agency which is updating the Bay Delta Plan. This Plan is intended to protect water quality through water flow and mandates increased flow into the Delta, but the draft Plan would have significant and detrimental impacts to Solano County. 

Impacts of the Bay Delta Plan 

Restrictions to Lake Berryessa

The State's proposed '55% unimpaired flows' would have a direct and significant impact on Lake Berryessa and the communities that depend on it. This amounts to approximately 144,000 acre-feet of water. Furthermore, the Plan would require Lake Berryessa to be kept at 65% capacity, regardless of drought conditions. This would effectively eliminate our drought resiliency, as it represents a 3-year water supply that our communities would not have access to. 

Local Economic Impact 

For Suisun City, the proposed plan would reduce our water allocation from 1600-acre feet to 400-acre feet. Such a drastic reduction would not only impose building moratoriums on our city, which could put our financial solvency in jeopardy, as well as additional impacts such as affordability of housing in the Bay Area. In addition to preventing the City from being able to build new housing, which would have a ripple effect throughout the Bay Area. There are extremely limited options for acquiring the necessary amount of water to meet our current obligations in the community if we were restricted to our current water supply.

Healthy Rivers and Landscape Proposal - A Better Alternative

Voluntary Agreements, specifically the Healthy Rivers and Landscape Proposal, represent a suite of solutions among State, Federal, and local water leaders as an alternative to the State’s proposed unimpaired flow updates. It is a balanced approach, taking into consideration flow, habitat, science, and funding for a holistic approach. Voluntary Agreements seek to fulfill the State’s objectives of protecting watersheds and preserving ecological needs while supporting sustainable economic growth at the local level. The Healthy Rivers and Landscape Proposal would ensure Lake Berryessa's preservation as a vital water source for Solano County.
