California has never had an easy relationship with its water, and right now the state finds itself navigating one of the more consequential stretches in that long, often contentious history. Four separate but connected fights are unfolding at once, and how each one resolves will help shape water policy in California for decades to come.
The Colorado River remains the most volatile flashpoint. Shrinking snowpack in the Rockies has pushed both Lake Mead and Lake Powell toward dangerously low levels, and federal officials have spent years trying to get California, Arizona, Nevada and other states that rely on the river to agree on how to share the pain of a shrinking supply. So far, consensus has proven elusive. California draws less from the river than its neighbors, but that hasn’t kept the region out of the fight. When the Bureau of Reclamation recently stepped in with temporary rules governing river operations, Nevada responded with a lawsuit, and Arizona has signaled it may do the same.
Closer to home, momentum is building behind the long-discussed Sites Reservoir, an off-stream storage project planned for the west side of the Sacramento Valley. The idea of capturing extra water during wet years and holding it for drier times is not new, but concerns about diminishing snowpack have given the project fresh urgency. Gov. Gavin Newsom is pushing to finalize the project before his term ends in four months, and the State Water Resources Control Board recently released a draft decision on the water rights Sites would need. Before the reservoir — envisioned to hold 1.5 million acre-feet of water — can move forward with financing, it must first secure the right to draw from the Sacramento River.
Newsom is also racing to advance another ambitious and long-stalled project: a tunnel that would reroute Sacramento River water around the Sacramento-San Joaquin Delta, improving deliveries south through the California Aqueduct. Conveyance projects like this have been debated in some form for more than six decades without ever making it across the finish line. Supporters argue the tunnel would relieve stress on the Delta’s fragile ecosystem, while opponents, including several environmental organizations, warn it could deepen existing problems. Assembling the regulatory approvals and financial commitments needed from water agencies that stand to benefit has proven just as difficult this time around.
Meanwhile, a separate but related struggle is playing out over the San Joaquin River. Even as the state pushes forward with a plan to divert Sacramento River water away from the Delta, it is simultaneously asking San Joaquin Valley farmers to send more water into the Delta by cutting back on their own river diversions. Those reductions were originally framed as voluntary, but state officials have been preparing mandatory measures in case voluntary offers fall short. Last week, Westlands Water District — the largest in the valley — withdrew from voluntary talks, arguing the state was steering the process toward coercion rather than cooperation. If mandatory cutbacks are eventually imposed, a legal fight over the state’s authority to override established water rights seems likely.
Adding to the tension are ongoing restrictions on how much water farmers can pump from underground aquifers. Some projections suggest that shrinking water supplies could force as much as 900,000 acres of farmland out of production altogether. That threat prompted major agricultural groups to lobby state lawmakers last week, successfully pushing through legislation that makes it easier to convert farmland currently protected as open space into sites for solar energy development.
Taken together, these four battles — over the Colorado River, the Sites Reservoir, the Delta tunnel and San Joaquin River diversions — represent the central fault lines in California’s water future. How state and federal officials navigate them in the months ahead will go a long way toward determining who gets water, how much, and under what terms, for generations to come.
