A court docket has upheld a key determination by California’s water board calling for reductions in water diversions from the San Joaquin River and its tributaries to assist revive struggling fish populations.
In his ruling, Sacramento County Superior Courtroom Decide Stephen Acquisto rejected lawsuits by water districts serving farms and cities that may be required to take much less water underneath the requirements adopted by regulators. The decide additionally rejected challenges by environmental teams that had argued for requiring bigger cutbacks to spice up river flows.
The decide’s ruling, issued in a 162-page order final week, helps the State Water Sources Management Board’s 2018 adoption of a water high quality plan for the decrease San Joaquin River and its three main tributaries — the Tuolumne, Merced and Stanislaus rivers.
The water high quality requirements, which concentrate on a portion of the Sacramento-San Joaquin River Delta watershed, set targets for growing river flows to assist populations of chinook salmon and steelhead trout, which have declined dramatically.
“The choice is critical as a result of it reaffirms the board’s authority to train each water rights and water high quality authority to guard native fishes, and to assist restore flows which can be obligatory for native fish,” mentioned Michael Lauffer, chief counsel for the state water board.
Companies that had sought to problem the state’s plan included massive agricultural suppliers such because the Merced Irrigation District and Westlands Water District, in addition to city suppliers such because the San Francisco Public Utilities Fee and town of Modesto.
The choice gives authorized backing for California’s water board to finalize guidelines requiring that extra water be left within the Merced, Tuolumne and Stanislaus rivers for fish and the ecosystem. Environmental teams have argued that whereas extra water within the rivers is urgently wanted, the state’s plan doesn’t go far sufficient to guard salmon and different fish.
At present, greater than 80% of the rivers’ flows are diverted at occasions to produce farms and communities, leaving lower than 20% of the pure flows within the rivers, Lauffer mentioned. As soon as the requirements are applied, he mentioned, the state board’s plan requires limiting diversions throughout sure occasions of yr to between 50% and 70% of complete river flows — with the objective in the course of that vary.

State officers have for years been engaged within the advanced means of growing updates to the water high quality plan for San Francisco Bay and the Sacramento-San Joaquin River Delta. It took 9 years of research and deliberations earlier than the state water board adopted the requirements for the tributaries alongside the San Joaquin River.
State officers are contemplating choices for updating requirements for the Sacramento River and the remainder of the delta watershed.
“These are extremely difficult science, authorized and coverage points,” Lauffer mentioned. “This determination is necessary, although, as a result of it exhibits that regardless of these challenges, when the board strikes ahead, rigorously considers the science, rigorously considers the general authorized framework, it will probably train its authority in an affordable means to enhance water flows and enhance situations in order that we are able to reverse the precipitous decline of the delta.”
The decide famous in his ruling that the targets underneath the state-approved plan present for elevated flows downstream from dams on every of the tributaries to assist shield fish populations.
“With extra water being launched into the tributaries and required to stay within the rivers to help the ecosystem for these fish populations, there shall be much less water out there for diversion” to produce farms and cities, the decide wrote.
Whereas a lot of the plaintiffs sued in 2019 to problem the state requirements for river flows, some water businesses within the delta additionally sought to problem a provision governing salinity ranges. And the federal authorities, which initiated its swimsuit in the course of the Trump administration, argued that the state board hadn’t complied with necessities of the California Environmental High quality Act.
The decide disagreed, rejecting a complete of 12 lawsuits and 116 claims. The court docket dominated that the state water board complied with its obligations underneath state legal guidelines — one among which is the Porter-Cologne Act, the state’s water high quality regulation.
Appeals are anticipated within the case, Lauffer mentioned. “I feel all of us acknowledge that finally the courts of enchantment or the California Supreme Courtroom will resolve a few of these points.”
The state water board has but to implement the water high quality requirements for the San Joaquin River. As an preliminary step, the board adopted organic targets final yr that may information the implementation effort, which may also decide how the reductions will have an effect on every water person.
“Finally, as further flows are left within the river for the good thing about fish and for the ecosystem, it can require belt tightening across the bay-delta watershed,” Lauffer mentioned. “Sadly, the processes in California water high quality and water rights regulation usually are not fast. We’re nonetheless seemingly greater than a yr away from ultimate actions that may see will increase within the flows in these tributaries.”
Felicia Marcus, who oversaw the plan’s adoption in 2018 as chair of the state water board, mentioned she is happy the court docket supported the board’s determination and method.

“As a lawyer, I felt fairly snug that we have been on very strong floor,” Marcus mentioned. “It’s simply good to have validation and vindication that what we did was nicely based and proper.”
Marcus mentioned that whereas offering much more water for fish can be good “for those who had a magic wand,” the board and the company’s employees carried out a good and complete course of that weighed the science and struck a good steadiness.
“The job of the board is to steadiness. And it’s all the time exhausting as a result of steadiness is within the eye of the beholder,” Marcus mentioned.
The board’s 2018 determination was contentious, assembly with sturdy opposition from managers of water districts. Lawsuits adopted. In 2019, Marcus left workplace when Gov. Gavin Newsom declined to reappoint her.
The court docket ruling coincides with ongoing heated debates about how water must be managed within the delta to guard threatened and endangered fish at a time when human-caused local weather change is placing rising strains on water provides and ecosystems.
Chinook salmon populations have declined sharply in recent times. Environmental and fishing teams have additionally pointed to a latest improve within the deaths of threatened steelhead at pumps operated by state and federal managers.
In a grievance that’s being investigated by the federal Environmental Safety Company, a gaggle of Native tribes and environmental teams have accused the state water board of discriminatory practices and mismanagement contributing to the delta’s ecological deterioration.
Whereas the state water board considers options for updating water high quality requirements and move necessities all through the delta watershed, the Newsom administration has promoted negotiated “voluntary agreements” — referred to as Agreements to Assist Wholesome Rivers and Landscapes — during which water businesses pledge to forgo sure quantities of water whereas additionally funding initiatives to enhance habitats for fish within the delta.
Marcus, now a researcher at Stanford College, mentioned in a latest report she co-wrote with different specialists that whereas voluntary agreements may be helpful, it’s additionally important that the state have sufficient regulatory necessities in place to make sure enough water for the atmosphere.
The court docket determination now provides the board “an ideal basis on which to complete the job” by adopting and implementing requirements all through the delta and for different rivers that feed into it, Marcus mentioned.
Implementing the requirements alongside the over-diverted tributaries of the San Joaquin River will imply roughly doubling the quantity of water within the rivers for fish throughout sure occasions of yr, and managing the dams with extra precision to restrict diversions and shield the ecosystem, she mentioned.
In concept, a voluntary settlement with water suppliers may be efficient, so long as there are laws in place, Marcus mentioned. “However the settlement’s acquired to be adequate, which incorporates including sufficient water to the system that the fish have a combating probability.”
At present, state officers say that greater than 80% of flows within the tributaries are recurrently diverted in below-average or dry years. However at occasions, much more water has been diverted. And in some instances, little or no water has been left flowing.
After a stretch of the Merced River ran dry in the course of the extreme drought in the summertime and early fall of 2022, federal fisheries officers urged the state water board to research and take steps to stop the dewatering of the river.
Eric Oppenheimer, the board’s government director, mentioned in a January letter to the Nationwide Marine Fisheries Service that his company’s employees have been investigating to “determine components inflicting or contributing to the noticed dry riverbed situations,” which he mentioned can embody drought, river diversions and groundwater pumping.
He mentioned it’s potential that “the complete move of the river might have been legally diverted when dry situations have been noticed,” and that the board is weighing approaches to maintain the Merced River flowing to its confluence with the San Joaquin year-round.
The environmental group Pals of the River has referred to as for the state water board to undertake everlasting laws to make sure the Merced River continues flowing in the course of the dry season.
The state water board has set a objective of preserving 40% of the full “unimpaired” move within the three rivers from February by way of June. There isn’t a minimal in-stream move requirement for decrease stretches of the tributaries from July by way of January, however state officers say the brand new objective gives for supplementing flows throughout these months to keep away from dangerous situations for fish.
Implementing the requirements will contain analyzing the water-rights seniority system and allocating reductions. Marcus mentioned that may in all probability be yet one more hard-fought battle, however she hopes the court docket determination “provides a little bit extra leverage to the voices of motion versus the voices of litigation and dissension.”
Managers of water districts that had sued to problem the state’s plan voiced help for the voluntary method.
“The lawsuit for us was actually about having an open, truthful and clear course of,” mentioned Elizabeth Jonasson, a spokesperson for Westlands Water District. “And we consider there’s a higher means, which is working collectively, that gives higher outcomes, and that’s why we’re supporting the voluntary agreements transferring ahead.”
Officers on the San Francisco Public Utilities Fee, which provides 2.7 million residents and hundreds of companies within the Bay Space, expressed disappointment and mentioned they’re reviewing the ruling.
“This 2018 determination might considerably impression our water provide with rationing of as much as 50% in prolonged droughts,” mentioned Nancy Hayden Crowley, a spokesperson for the fee. She mentioned the company is specializing in the proposed Agreements to Assist Wholesome Rivers and Landscapes as “one of the best alternative to steadiness California’s water useful resource wants and enhanced environmental stewardship of the Sacramento-San Joaquin Bay Delta.”
Mike Jensen, a spokesperson for the Merced Irrigation District, mentioned the water that’s at stake has supported the district’s group for greater than a century. He referred to as the state’s plan unfair and “unbalanced” and mentioned the district “will proceed to pursue any, and all, authorized avenues to guard our deprived communities and their entry to water.”

San Francisco Baykeeper and different environmental teams had argued that the state’s plan for growing river flows, whereas helpful for fish, would fail to satisfy the board’s targets of doubling numbers of salmon and supporting viable fish populations.
Jon Rosenfield, Baykeeper’s science director, famous that the decide didn’t disagree with this view, however decided that the board’s requirements would “fairly shield” fish.
“We consider the board is required to develop a plan that’s prone to truly attain the goals it units,” Rosenfield mentioned.
He mentioned the present stage of diversions has decimated fish populations and is unsustainable. The proposed voluntary agreements would offer a lot much less water for the atmosphere than required underneath the state board’s plan, Rosenfield mentioned.
With this court docket ruling, he mentioned, the board “can now act to enhance environmental situations.”
He mentioned the choice additionally signifies that agricultural water districts and cities together with San Francisco “can now be very sure that they need to plan for a future the place the water they divert from the San Joaquin and its tributaries will generally be restricted.”
