California Water Issues

Our Water Committee monitors and recommends action on issues concerning water in our state. The committee is always interested in learning about major water initiatives going forward around the state. Contact us for more info: water @

California's Water and Our League

The Water Committee is sharing a series of articles written for lay folks describing the enormously complex California water system. Check it out here.

Water in California

Voters will continue to face large water-related expenditures in the coming years. Making informed decisions on these investments in managing California’s water resources is difficult, given unclear answers to key questions such as:

  • How should limited and unpredictable freshwater supplies be allocated among competing municipal, industrial, agricultural, and environmental uses?
  • Who is responsible and accountable for managing surface water and groundwater supplies and quality?
  • How much will it cost to ensure safe and reliable supplies for a growing population and for damaged ecosystems? Who should pay?
  • How will we pay to build new infrastructure and maintain aging infrastructure to deal with drought, flood risks, and climate fluctuations?

What is the League doing on water issues?

2019 Dam removal on the Klamath River (North Coast Hydrologic Region)
In February, at the urging of LWV Humboldt County, LWVC sent a letter of support to the State Water Resources Control Board for its Draft Environmental Impact Report calling for removal of four dams on the Klamath River. The letter says, “The removal of the four dams will effectively improve water quality for humans, fish, and other wildlife and comply with the Clean Water Act water quality objectives. The improved water quality will also provide for the cultural and economic interests of Native Americans, recreational anglers, and the commercial fishing fleet of northern California.”

2019 Clean Water effort (South Coast Hydrologic Region)
In March, LWV Orange Coast in Orange County received permission from LWVUS to urge the US Environmental Protection Agency (EPA) to keep the 2015 Waters of the United States (WOTUS) rule, which provided for protection of lakes, estuaries, and wetlands. (Local Leagues wishing to comment on federal proposals must submit a Request to Take Action form to the national League.) LWV Orange Coast wrote, “We are particularly alarmed by the threat the proposed change represents to preservation of our wetlands. Many of our 215 members live on or near the coast and have long been active in protection and preservation activity in the wetlands of the Banning Ranch Conservancy, the Bolsa Chica Ecological Preserve, the San Joaquin Marsh Reserve, the wetlands of the Upper Newport Bay and similar areas. The League believes that it is vital to have policies which support water quality, that is essential to maintaining species populations and diversity. These policies include measures to protect lakes, estuaries, and wetlands. The proposed changes would have a drastic negative effect. Please keep the 2015 WOTUS rule in place.”

The EPA later revised its definition of Waters of the US and the federal Clean Water Act to make them less protective. The Clean Water Act regulates the discharge of pollutants into the nation's surface waters, including lakes, rivers, streams, wetlands, and coastal areas. LWVUS has been a strong supporter of the Clean Water Act.

2019 Sites Reservoir activities (Sacramento River Hydrologic Region)
The LWVC Water position calls for discouraging additional on-stream storage (such as Temperance Flat Dam on the San Joaquin River) but encouraging off-stream storage. Sites Reservoir is off-stream storage, but League members in the Sacramento Valley and the Bay-Delta have long had concerns about the physical location of Sites, the proposed water supply, water quality of stored water, and the impact of its proposed operation on the balance of groundwater and surface water in the Sacramento Valley. In April, the Water Committee considered submitting comments to the California Water Commission on the Sites Reservoir project, based on concerns about water quality, but determined that it was too late in the Water Commission’s process of approving storage projects for funding under Prop 1 to submit a comment letter. Redding Area LWV is continuing to follow development relative to the Sites Project.

2019 Delta Conveyance and the Water Resilience Portfolio activities (San Joaquin and San Francisco Bay Hydrologic Regions)
Shortly after Governor Newsom took office in January 2019, he declared an end to WaterFix, a plan for twin tunnels under the Sacramento-San Joaquin Delta, and he signaled support for consideration of a range of options to reduce reliance on the Delta, with a single Delta tunnel being one possible option. Nevertheless, the Delta Conveyance Design and Construction Authority/Delta Conveyance Finance Authority charged with developing a tunnel plan continued its work. The State Water Contractors continued negotiations with DWR on how much water a new Delta conveyance (DCF) would move, who would pay for building a DCF, and how much water would be allocated (or denied) to non-paying agencies. This involved amendments to water supply contracts. A stakeholder engagement committee was formed to advise on impacts and began meeting late in the year. The SWP contract negotiation process was difficult for the public to follow (for example, some documents were missing or delayed in being posted). The stakeholder engagement committee formed by the Conveyance Authority was not given the option of recommending “no conveyance.”

In April, the Governor issued an executive order directing state agencies to develop a Water Resilience Portfolio of recommendations to meet California’s water challenges. Environmental interests that participated in the Water Resilience Portfolio stakeholder process do not generally think that their concerns were addressed and see in the Portfolio a continued commitment to large water infrastructure, instead of to regional self-sufficiency and water conservation that would reduce reliance on unsustainable water transfers, including transfers through the Delta. The Water Resilience Portfolio does not include alternatives to a tunnel under the Delta.

2019 Water recycling efforts (Central Coast Hydrologic Region)
The LWV Monterey County received the LWVC's permission to comment in December on a water issue involving a decision by the California Coastal Commission, a state agency. LWV Monterey County supports Pure Water Monterey, a collaborative regional approach to providing recycled drinking water for the Monterey Peninsula, enhancing water supply reliability by diversifying local water sources. Consideration of the project faces opposition from California American Water (CalAm), an investor-owned public utility proposing construction of a desalination plant. CalAm argues that the Pure Water Monterey project is not sufficient to provide for water needs in the area over the long run and that their desalination facility is necessary. Pure Water Monterey supporters argue that Pure Water’s expansion is sufficient to meet long-term needs. There are also concerns that the desal operation could cause saltwater to seep into the Salinas Valley Groundwater Basin, the aquifer that provides freshwater to much of Monterey County. An early analysis by the California Coastal Commission found that there were less environmentally harmful alternatives to the desal project. The Coastal Commission’s final determination is expected in March 2020.
Note: LWVC does not have a position supporting or opposing desalination.
