Russian River communities feel blindsided by recent changes to flood zones

A change to federal flood zones could affect insurance rates, property values and building, especially along the lower Russian River.

Nick Schwanz went to a Sonoma County Board of Supervisors meeting in November to weigh in on a particular agenda item.

He was surprised to learn, however, that another item, which appeared to be a routine and technical set of zoning adjustments, actually carried huge implications for his community.

Schwanz, a board member of the Russian River Chamber of Commerce, quickly pivoted and became one of the few to comment on an apparent change to the federal flood zones that could affect insurance rates, property values and building especially along the lower Russian River.

“As far I know this isn’t on anybody’s map,” Schwanz said.

Supervisors, too, seemed taken by surprise.

“This was sort of framed to me as technical corrections, and honestly the way the data was presented made it impossible to see the bigger picture,” said Fifth District Supervisor Lynda Hopkins, who represents much of the affected area. “When we have constituents coming to us who received a notice in the mail yesterday and have no idea what it means, that’s a failure of community engagement. That’s a failure of communication, and we need to do better. I can’t in good conscience vote on this.”

At issue was a new study by the Federal Emergency Management Agency of flood hazards in the Russian River Watershed, the first update in 30 years. The maps are used to determine flood risks and insurance requirements and must be adopted by counties to participate in the National Flood Insurance Program.

Spawning Chinook salmon return to Sonoma Creek in wake of recent storms

Martin Espinoza, PRESS DEMOCRAT

Copious early rainfall and efforts aimed at restoring local salmon and steelhead trout habitat have made such scenes possible, local ecologists say.

A female Chinook salmon swam steadily against the current in a shallow section of Sonoma Creek as several male fish splashed about behind her, jockeying for position, waiting for her to lay her eggs.

Just a few yards downstream on Wednesday, near the bank of the creek, another female rolled onto her side and smacked the gravel and rocks with her tail, doing her part to dig a “redd” or nest as the current flushed away silt and sediment that can be harmful to egg development.

This spawning scene for Chinook, or king salmon, in the headwaters of Sonoma Creek within Sugarloaf Ridge State Park is an uncommon sight for most local residents.

But since late November, hundreds of Chinook have traveled up the watershed from San Pablo Bay and been spotted in numerous tributaries that drain Sonoma Valley and its surrounding elevations.

Heavy rains in November and December have created ideal stream flows that have allowed spawning salmon to make their way into the region’s headwaters, said Steven Lee, research program manager of the Sonoma Ecology Center, which monitors the health of the Sonoma Creek watershed.

Sonoma County must suspend non-emergency well drilling under court order

Emma Murphy, PRESS DEMOCRAT

It is the latest development in a lengthy 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.

Sonoma County has once again suspended permitting for non-emergency well drilling, this time under the order of a Sonoma County judge.

The order follows an August ruling in which Superior Court Judge Bradford DeMeo determined the county violated state environmental law in its attempt to draft a controversial ordinance governing wells and groundwater use.

In light of that finding, the county must halt non-emergency well-permitting until it can complete an environmental review of the ordinance in alignment with state law, the court ordered.

California governor signs law banning all plastic shopping bags at grocery stores

APNEWS

“Paper or plastic” will no longer be a choice at grocery store checkout lines in California under a new law signed Sunday by Gov. Gavin Newsom that bans all plastic shopping bags.

California had already banned thin plastic shopping bags at supermarkets and other stores, but shoppers could purchase bags made with a thicker plastic that purportedly made them reusable and recyclable.

The new measure, approved by state legislators last month, bans all plastic shopping bags starting in 2026. Consumers who don’t bring their own bags will now simply be asked if they want a paper bag.

State Sen. Catherine Blakespear, one of the bill’s supporters, said people were not reusing or recycling any plastic bags. She pointed to a state study that found that the amount of plastic shopping bags trashed per person grew from 8 pounds (3.6 kilograms) per year in 2004 to 11 pounds (5 kilograms) per year in 2021.

Blakespear, a Democrat from Encinitas, said the previous bag ban passed a decade ago didn’t reduce the overall use of plastic.

“We are literally choking our planet with plastic waste,” she said in February.

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

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.

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.
