Watching native fishes vanish

Andrew Rypel & Peter Moyle, CALIFORNIA WATER BLOG

It’s an odd, disturbing feeling – watching populations of native fish species collapse and then disappear. Sometimes it happens quickly, other times it’s a series of slowstep change events. The end result is the same though – smaller populations, extinctions, less biodiversity. We put up a little fight, and occasionally have moderate success. But by and large, the overall trend is down, the pace of change quickening, and it is relentless. We’ve watched it over our careers, and maybe some of you have too. Either as biologists or water professionals, or perhaps as long-time readers of this blog. This summer has been no different. It has been an avalanche of stories, all with variations on this theme. Here, we provide a synopsis of some recent events, along with wider thoughts on what watching this happen means.

When we lose species, it speaks volumes about our inability to prevent ecosystem decline, and to constantly borrow from nature without repayment (Rypel 2023). The pattern is especially sobering with charismatic species such as Chinook salmon, which receive large amounts of conservation funding and attention. This is a clear and unambiguous signal that cannot be ignored. But what should we do about it? A good start might be the development and implementation of a comprehensive fish management plan for California. We provided some scaffolding for what such a plan might look like in a previous blog. The 30×30 conservation goal of the Resources Agency can boldly protect many declining fishes if fully implemented. This initiative seeks to directly protect entire watersheds, including where many declining fish occur.

Judge strikes down Sonoma County rules governing wells, groundwater use, siding with environmental groups

Emma Murphy, PRESS DEMOCRAT

The court decision is the latest turn in a yearslong legal fight between Sonoma County and environmental groups who contend the county is not doing enough to study and regulate heavy groundwater pumping and its impact on streams and aquatic wildlife.

Sonoma County violated state environmental law in its latest attempt to draft a controversial ordinance governing wells and groundwater use across a wide swath of the region, a Sonoma County judge has ruled.

Superior Court Judge Bradford DeMeo’s ruling throws the county’s 16-month-old rules into limbo and raises questions about how permitting for new wells may be affected for rural residents and farmers across more than 300 square miles, or nearly a fifth of the county.

The county has not outlined the immediate implications for those permit applications. A county spokesman said the ruling was still be reviewed.

The court decision is the latest turn in a yearslong legal fight between the county and environmental groups who contend heavy groundwater pumping is doing harm to streams and aquatic wildlife. The county, those groups say, must conduct deeper study of those impacts and craft stronger regulations to safeguard natural resources that belong to the public.

Salmon and the subsurface

David Dralle, Gabe Rossi, Phil Georgakakos, Jesse Hahm, Daniella Rempe, Monica Blanchard, Mary Power, Bill Dietrich, and Stephanie Carlson, CALIFORNIA WATERBLOG

Our central hypothesis is that we will not recover salmon abundance without recovering a diversity of paths through the watershed and through the life cycle and, moreover, that the strategies that are missing or only weakly contributing today are ones that relied on the mainstem and other non-natal habitats for rearing / as stop over sites…

You’ve probably noticed that some streams flow year-round while others are seasonally dry, despite receiving similar amounts of rainfall. Through a recent NSF-funded effort (“Eel River Critical Zone Observatory”), we learned several things about how landscapes filter climate to produce such diverse flow behavior–and the implications for how salmon live their lives.

Our 25-year field study revealed that belts of California’s Eel River watershed underlain by different geologies have different Critical Zones (CZs) – Earth’s permeable surface layers from the top of the vegetation canopy down to fresh bedrock, where water can be stored and exchanged.

Federal judge: Russian River dam releases are violating Endangered Species Act

Andrew Graham, PRESS DEMOCRAT

A federal judge ruled Monday that the U.S. Army Corps of Engineers has violated the Endangered Species Act by disturbing salmon populations through flood-control releases from Coyote Valley Dam into the Russian River.

Those releases, which relieve pressure upstream from the 66-year-old dam during rainy months, kick up sediment from the bottom of Lake Mendocino, a reservoir that serves as critical water storage for Sonoma County.

The sediment increases turbidity in the river that harms and harasses coho and chinook salmon and steelhead trout in violation of the Endangered Species Act’s mandate to protect the imperiled species, U.S. District Court of Northern California Judge Jacqueline Scott Corley ruled.

Corley ruled on a lawsuit brought by Sean White, who has spent much of his career involved in the Russian River in one way or another, serving as general manager of the Russian River Flood Control and Water Conservation Improvement District before moving in 2015 to direct sewage and water services for the city of Ukiah.

White brought the lawsuit as a private citizen. The Endangered Species Act, one of the nation’s bedrock environmental laws, allows for citizens to sue governments, businesses or individuals they believe to be violating the act.

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.

New restoration plan for Laguna de Santa Rosa

Laura Hagar Rush, SEBASTOPOL TIMES

The Laguna de Santa Rosa held an open house on Wednesday, February 21, to celebrate the release of the Laguna de Santa Rosa Restoration Plan. Funded by a grant from the California Department of Fish and Wildlife with matching funds from Sonoma Water, this document examines six potential restoration projects in the Laguna de Santa Rosa watershed.

Presented by Neil Lassettre of Sonoma Water and Scott Dusterhoff of the San Francisco Estuary Institute (SFEI), this plan was several years in the making.

“So six years ago, we were here with folks from the public, many of you here in this hall, saying ‘Well, we were going to do this restoration planning effort.’ And here we are six years later, unveiling this restoration plan to you all. So this is really an exciting time for us,” Dusterhoff said.

Dusterhoff explained the two major phases of the project this way: “The first component was developing an understanding of how the Laguna used to look and how it used to function and the habitats that it was supporting. So that’s developing an understanding of the historical ecology,” he said. “And then after we understand how the Laguna used to look and how it used to function, we can understand the landscape change—so the magnitude of change from what was to what is. So that was part number one. Part number two then was using that information to develop this long term restoration vision—this long term idea of all of the habitats we want to bring back in the Laguna. So then, we took that vision and we dove deep on a few areas, and we came up with this master restoration plan,” he said.

Press Release: Governor Newsom launches California’s ‘Salmon Strategy for a Hotter, Drier Future’

Office of Governor Gavin Newsom

WHAT YOU NEED TO KNOW: To restore populations of salmon amidst hotter and drier weather exacerbated by climate change, Governor Newsom announced California’s first strategy to protect the iconic fish species for generations to come.

Governor Gavin Newsom today announced new actions and efforts already underway that California is taking to help restore California’s salmon populations.

Salmon Strategy for a Hotter, Drier Future

After 10 years of rapidly intensifying drought and more extreme weather, salmon are not doing well. Last year, with projections showing Chinook salmon population at historic lows, the salmon season was closed and the Newsom Administration requested a Federal Fishery Disaster to support impacted communities. Additionally, due to crashing salmon populations in 2023, some tribes canceled their religious and cultural harvests for the first time ever.

The strategy’s six priorities call for:

1. Removing barriers and modernizing infrastructure for salmon migration
2. Restoring habitat
3. Protecting water flows in key rivers at the right times
4. Modernizing hatcheries
5. Transforming technology and management systems
6. Strengthening partnerships

Sonoma, Mendocino county water managers propose pathway for continued Eel River diversions

Mary Callahan, PRESS DEMOCRAT

Water managers in Sonoma and Mendocino counties seek to preserve water transfer infrastructure as part of PG&E license surrender for Potter Valley power plant.

Water managers in Sonoma and Mendocino counties have submitted a conceptual proposal to PG&E to buy and maintain portions of the utility’s defunct Potter Valley power plant to enable future water transfers.

The move would be a critical step toward preserving seasonal diversions of Eel River water to supplement supplies in Lake Mendocino and the Russian River.

Working with the Mendocino County Inland Water and Power Commission and the Round Valley Indian Tribes, the Sonoma County Water Agency is seeking to preserve elements of the power plant through which water is channeled from the Eel River to the East Fork Russian River. No electricity would be generated as a part of the plan.

Pacific Gas & Electric has planned to surrender its license for the 1908 plant with the intent of decommissioning it. Without a proposal to save it, the diversion infrastructure would eventually be removed, leaving upper Russian River communities and agriculture users without sufficient water.

Sonoma, Mendocino County grape growers battling new rules designed to reduce sediment, pesticides in local waterways

Mary Callahan, PRESS DEMOCRAT

A new program targeting 1,500 commercial grape growers in Sonoma and Mendocino counties and designed to improve water quality in local creeks and rivers is drawing criticism from members of the agricultural community.

The draft rules include reporting requirements, annual fees, well and groundwater monitoring, ground cover requirements and restrictions on wintertime operations that growers deem excessive.

Vineyard operators and agricultural representatives say the costs and mandates are overkill for an industry that is already working to reduce sediment runoff into waterways and protect fish habitats.

Small growers are especially likely to suffer because “their margins are really small, and the proposed permit is going to create costs that are significant to them,” said Robin Bartholow, deputy executive director of the Sonoma County Farm Bureau.

But staff of the North Coast Regional Water Quality Control Board say the soil disturbance and chemical use in many vineyards, as well as potential disruption of riparian plants needed to shade fish habitat, can degrade water quality in creeks and rivers.

Op-Ed: Eel River dam debate echoes nationally

Cameron Nielson & Sarah Bardeen, THE PRESS DEMOCRAT

On paper, California’s Eel River is a prime candidate for restoration.

It’s a remote river that runs through rugged, lightly populated terrain in Northern California. As with many rivers in the region, a combination of logging, overfishing and dams decimated its once-plentiful salmon and steelhead runs. The introduction of a native predator, the pikeminnow, only made things worse.

But some of that could be put to rights: two aging dams in the Eel’s upper reaches are reaching the end of their life span — and one has been declared seismically unsafe. PG&E, which owns the dams, has chosen not to renew their licenses, setting the stage for removal if no new owner steps forward.

Eel River residents overwhelmingly support dam removal, the tribes are adamantly in favor, and a constellation of NGOs is pushing hard for it. If those dams come down, 150 square miles of cold-water habitat will open up to struggling populations of steelhead and salmon, offering needed refuge from the warming climate.

So why is it so hard to get done?

Part of the answer lies in the dam’s history. Part lies in the challenges of coping with a surfeit of aging infrastructure. And part lies in the complexities of who exactly constitutes the river’s community. Finding a solution has implications not just for the state but for the nation.
