Op-Ed: Diversion won’t guarantee a healthy Russian River

Don McEnhill and Ed Burdett, PRESS DEMOCRAT

When PG&E announced that it would remove Scott and Cape Horn dams on the Eel River as part of the Potter Valley hydroelectric project decommissioning, it put a continuing water diversion to the Russian River in question.

A Press Democrat editorial praised Eel and Russian River stakeholders coming together to endorse the possibility of a new fish friendly diversion from the Eel River (“Progress toward water security,” March 27), and we at Russian Riverkeeper concur. However, a continued diversion from the Eel River is not a solution in and of itself when it comes to ensuring long-term water reliability in the upper Russian River watershed. A continued diversion will not solve all the region’s water issues.

Russian Riverkeeper, a Healdsburg-based nonprofit organization founded in 1993 to ensure that river water is drinkable, swimmable, fishable and equitably shared, is supportive of the effort to create a wintertime diversion that allows salmon and Pacific lamprey in the Eel River maximum recovery potential, while still making surplus flows available to the Russian.

Op-Ed: Saving rainwater for sunny days to come

Grant Davis, PRESS DEMOCRAT

The current water year, which began Oct. 1, has been wetter than usual, with the Russian River watershed accumulating 119% of the yearly average rainfall, totaling 49.38 inches since October.

In the past, we might have celebrated our good fortune and watched lake levels rise only to watch much of it sent downriver to the Pacific Ocean as reservoirs reached an inflexible upper threshold. Today, we get to continue enjoying that ample rainfall long after summer sunshine arrives.

With almost a decade of data under its belt, the Russian River Forecast-Informed Reservoir Operations program has been making great strides by demonstrating the viability of this strategy to operate reservoirs more effectively using modern technology and forecasting.

This year, we expect the new method to ensure an additional 19,000 acre-feet of water in the Lake Sonoma reservoir heading into the summer, just as it did last year, thanks to our ability to leverage weather forecasting techniques and adapt how we manage our reservoirs. Add to that another 9,000 acre-feet stored in Lake Mendocino. An acre-foot equates to 325,851 gallons.

That 28,000 acre-feet represents a substantial savings, or almost 65% of Sonoma Water’s annual demand, given that the agency is projecting its three-year average annual water sales to be just under 43,000 acre-feet.

California’s ocean salmon fishing season closed for second year in a row

Susan Wood, NORTH BAY BUSINESS JOURNAL

California’s commercial and recreational ocean salmon fishing season is set to be closed for the second consecutive year, another blow to the state’s beleaguered industry suffering from the combined fallout of drought, climate disruption and deteriorating ocean conditions.

Already, a new request is underway for yet another federal disaster declaration to help alleviate some of the wide economic damage from the closure, affecting not just the fleet but many associated businesses that depend on the fishery, one of the state’s most lucrative.

The Pacific Fisheries Management Council, which manages and monitors West Coast salmon stocks in the ocean, endorsed the option on Wednesday of a full closure through the end of the year, mirroring recommendations made to close the fisheries in 2023.

Many fishermen, already resigned to a severely limited season if any at all due to depleted stocks, had backed the full closure.

Sonoma County Board of Supervisors approves temporary halt in new wells

Emma Murphy, THE PRESS DEMOCRAT

Supervisor James Gore, whose north county district includes some of the county’s most prolific wine grape growing areas, voted against the moratorium.

The Sonoma County Board of Supervisors has imposed a six-month halt in all new wells countywide, a far-reaching move likely to impact residential and commercial property owners seeking to tap groundwater amid a historic drought.

The immediate drilling moratorium, which offers only a narrow exemption for emergency water needs, is meant to give the county more time to draw up a new set of well regulations aimed to safeguard surface and subsurface flows in the county’s major watersheds.

A 2021 lawsuit by the environmental group California Coastkeeper Alliance spurred the work toward new regulations, and the Board of Supervisors was scheduled to vote on the new rules Tuesday.

Instead, after hours of deliberation over a proposed well ordinance that would have established new requirements reflecting updated state policy for well permit applicants, the board voted 4-1 to impose a moratorium, seeking to buy time for additional work.

Supervisors cited concerns including the potential impact the ordinance would have on agricultural users, and potential legal ramifications connected to California’s environmental quality laws. The new regulations could affect any wells countywide that come under a new application or are up for renewal.

Water crisis slams tomatoes

Kim Chipman, WASHINGTON POST

Tomatoes are getting squeezed.

California leads the world in production of processing tomatoes – the variety that gets canned and used in commercial kitchens to make some of the most popular foods. The problem is the worst drought in 1,200 years is forcing farmers to grapple with a water crisis that’s undermining the crop, threatening to further push up prices from salsa to spaghetti sauce.

“We desperately need rain,” Mike Montna, head of the California Tomato Growers Association, said in an interview. “We are getting to a point where we don’t have inventory left to keep fulfilling the market demand.”

Lack of water is shrinking production in a region responsible for a quarter of the world’s output, which is having an impact on prices of tomato-based products. Gains in tomato sauce and ketchup are outpacing the rise in U.S. food inflation, which is at its highest in 43 years, with drought and higher agricultural inputs to blame. With California climate-change forecasts calling for hotter and drier conditions, the outlook for farmers is uncertain.

“It’s real tough to grow a tomato crop right now,” Montna said. “On one side you have the drought impacting costs because you don’t have enough water to grow all your acres, and then you have the farm inflation side of it with fuel and fertilizer costs shooting up.”

California Coastkeeper Alliance lawsuit challenges the County of Sonoma to protect public trust resources

California Coastkeeper Alliance

Today, California Coastkeeper Alliance filed a lawsuit in Superior Court to compel the County of Sonoma to consider and mitigate impacts to public trust resources caused by groundwater extraction in the Russian River watershed. As the Russian River watershed faces a drought emergency, California Coastkeeper Alliance is working to hold Sonoma County accountable to protect public trust resources and prevent over pumping of its waterways. Everyone will need to do their part to ensure the Russian River maintains sufficient flows through this drought, and that includes restricting groundwater pumping as surface water pumping rights are curtailed.

“Over-pumping groundwater has had and continues to cause significant, harmful effects on the flow of the Russian River and its tributaries,” says Sean Bothwell, Executive Director of California Coastkeeper Alliance. “The current drought only makes this problem worse and restricting surface diversions alone merely drives more groundwater pumping. Groundwater connected to surface waters must also be managed, so we can endure the current drought crisis and be more resilient for future drought extremes. Responsibly regulating groundwater use protects other water users, as well as fish and wildlife”

The Russian River, its tributaries, and the aquatic life that depends on their flows, such as endangered Coho salmon, are protected by the public trust doctrine under the California state constitution. Large, self-sustaining populations of Coho salmon once occupied rivers and streams within the Russian River watershed, but insufficient streamflow has negatively affected the recovery of local salmon populations.

Sonoma Water petitions state for critical water condition for Russian River as severe drought enters third consecutive year

SONOMA WATER

On Wednesday, May 25 Sonoma Water (Sonoma County Water Agency) filed Temporary Urgency Change Petitions (TUCP) with the State Water Resources Control Board to establish a Critical water supply condition for both the upper and lower Russian River as the drought continues.

Under Critical water supply conditions, the Russian River would have minimum instream flow requirements of 25 cfs and 35 cfs in the upper and lower river, respectively. If approved, this change will allow Sonoma Water to continue the minimum instream flows that the river is currently operating under and preserve water supply in both Lake Mendocino and Lake Sonoma.

The current petitions also commit Sonoma Water and its retail customers to a (the cities of Cotati, Petaluma, Rohnert Park, Santa Rosa and Sonoma; the town of Windsor; and Valley of the Moon and North Marin water districts) 20-percent reduction in total diversions from the Russian River between July 1 and October 31 compared to the same time period in 2020.

Endangered coho salmon battered by 3rd year of drought. Here’s why it matters

Mary Callahan, THE PRESS DEMOCRAT

The Russian River’s once celebrated salmon populations have long been imperiled by logging, development, gravel mining and other human activities that have eliminated flood plains, channelized river and stream flows, and limited the woody debris and shade that keeps the water cool enough for young fish to survive.

More intense and frequent droughts have further eroded conditions, not just for the coho, but for steelhead and chinook salmon, both listed as threatened under the federal Endangered Species Act.

They were once abundant in the cold, clear water of North Bay creeks and streams. Now, the survival of coho salmon is being challenged like never before.

The coho has a three-year life cycle that takes it from stream to ocean and back to stream to spawn the next generation.

But the changing climate now threatens the species at every life stage, raising new questions about their recovery.

It’s not just a species at stake. At risk is the very resilience of the forest and watershed that evolved around them, fed by marine nutrients brought upstream and deposited inland by adult spawners that, after reproducing, die and decompose.

“Salmon are a keystone species, which means they perform a really important ecosystem service,” said Sarah Nossaman Pierce, a California Sea Grant fisheries biologist with the Russian River Monitoring Program. “Salmon and steelhead (trout) bring marine-based nutrients into the system and essentially feed the forest, plants, birds and wildlife.”

The challenge, she said, is “ecosystem resilience”

“People say, ‘Why do you care about the salmon?’ Unfortunately, if they can’t survive, human beings aren’t far behind,” she said.

Despite significant early season rainfall, Russian River watershed diversion curtailments likely to resume in April

Katherine Minkiewicz-Martine, SOCONEWS

Curtailments on Russian River watershed diversions will likely resume this April as the outlook for a “miracle March” in rainfall looks grim.

Curtailments for certain water right holders were suspended in October after Sonoma County received significant rainfall, however, flows from the October and December storms are starting to taper off, according to Sam Boland-Brien, a supervising engineer with the California State Water Resource Control Board, Division of Water Rights.

“It’s going to be a really dry summer,” Boland-Brien said.

Boland-Brien and other experts from the California Department of Water Resources, Sonoma Water, the National Marine Fisheries Service and the Sonoma County Farm Bureau convened on March 10 for a virtual drought town hall to discuss water supply and drought conditions for the coming summer season.

The March 10 event was the first in a planned series of drought town halls as the county navigates through another year of dry conditions. Future town halls will focus on specific topics such as the Russian River, water quality, river recreation and groundwater conservation.

Op-Ed: Here is the first step to a sustainable water policy

Carolee Krieger, CALMATTERS

We do not have a water crisis. We have a water management crisis, and we must revamp our water policy to reflect a drier future.

Water that is promised in a contract but can’t be delivered is called “paper water” – shorthand for water that does not exist except in legal documents.

During its mid-20th century frenzy of dam and canal construction, California allocated much more water than it actually had. These paper water commitments far exceed the amount of water than is available in our reservoirs and rivers. According to a study from the University of California, Davis, “appropriative water rights filed for consumptive uses are approximately five times greater than estimated surface water withdrawals.”

What this restrained academic language reveals is a management crisis: no matter how much it rains and snows in California, we will always have a chronic water shortage because of overallocation.

Why is this happening? As the UC Davis study found, the state has promised five times more water than could ever be delivered. Accelerating climate change only compounds the problem: Virtually all reputable computer models confirm California will receive less snow in coming decades, meaning our water deficit will only grow.

Meanwhile, overallocation remains at the core of California Department of Water Resources policy. In 2021, the State Water Project could deliver only 5% of its contracted water.
