The Russian River drains the
sparsely populated, forested coastal area that stretches from San
Francisco to the Oregon border.
Along the Russian, federally funded dams have created Lake
Mendocino (at the Coyote Dam) and Lake Sonoma (Warm Springs Dam).
Locally built aqueducts channel water from these lakes into
growing Marin and Sonoma counties.
The Russian River is one of the most flood-prone rivers in
California, routinely overflowing during wet years. As storm
systems approach California, the wet bands of clouds are uplifted
by the Coast Range, releasing precipitation first and most
intensely on the coastal streams. One flood control dam is on the
Russian River and one on Dry Creek, a tributary to the Russian
River, which can capture about 20 percent of flood flows.
In addition to flooding issues, the Russian River faces other
challenges to balance competing demands for its water. In an area
that was once legacy to massive numbers of salmon and steelhead,
restoring the fishery has been a key focus, while water providers
must accommodate municipal needs as well as those of grape
growers in one of the world’s most prized wine-producing regions.
In a major twist, the Donald Trump administration is now
reviewing regional appeals to halt PG&E’s plans to
dismantle the Potter Valley Project. … In an April
14 letter, the Bureau of Reclamation responded to an inquiry
from Aaron Sykes, a board member of the Lake Pillsbury
Alliance, which represents the homeowners and stakeholders
fighting to keep Scott Dam, the structure that holds back Lake
Pillsbury. In the letter, which was reviewed by SFGATE, the
federal agency said funding for the project is “undergoing
reviews” to ensure it aligns with an executive order President
Donald Trump signed on his first day in office that directs the
government to explore any “undue burden” on the “use of
domestic energy resources” including, oil, coal and hydropower.
The long-anticipated expansion of Monte Rio Redwoods Regional
Park took a major step forward this week. The Sonoma County
Board of Supervisors approved Regional Parks’ application for
an $8 million state grant—key funding toward the $24 million
needed to acquire 1,517 acres of forestland near Monte
Rio. Save the Redwoods League plans to purchase the
property, currently owned by Mendocino Redwood Co., and
transfer it to Sonoma County Regional Parks by summer 2025. The
acquisition will expand the current 515-acre park to more than
2,000 acres, connecting protected land from the Russian River
to the Pacific Ocean. … The land includes young-growth
redwoods, Douglas fir, oak woodlands, and essential watershed
areas feeding the Russian River—habitat crucial for endangered
coho salmon and steelhead trout.
At its February 13, 2025, meeting, the Mendocino County Inland
Water & Power Commission (IWPC) discussed a landmark Memorandum
of Understanding (MOU) that sets the stage for a New
Eel-Russian Diversion Facility (NERF). … IWPC also
discussed efforts to restart the Army Corps of Engineers (ACOE)
Feasibility Study on raising Coyote Dam, a long-debated project
aimed at increasing water storage capacity in the Upper Russian
River Watershed. Coyote Dam was originally designed to be
36 feet taller, but funding shortfalls prevented the full
construction. Increasing the dam height would allow more water
to be stored for dry-season use, especially as flows from the
Potter Valley Project decrease.
Many of California’s watersheds are
notoriously flashy – swerving from below-average flows to jarring
flood conditions in quick order. The state needs all the water it
can get from storms, but current flood management guidelines are
strict and unyielding, requiring reservoirs to dump water each
winter to make space for flood flows that may not come.
However, new tools and operating methods are emerging that could
lead the way to a redefined system that improves both water
supply and flood protection capabilities.
California is chock full of rivers and creeks, yet the state’s network of stream gauges has significant gaps that limit real-time tracking of how much water is flowing downstream, information that is vital for flood protection, forecasting water supplies and knowing what the future might bring.
That network of stream gauges got a big boost Sept. 30 with the signing of SB 19. Authored by Sen. Bill Dodd (D-Napa), the law requires the state to develop a stream gauge deployment plan, focusing on reactivating existing gauges that have been offline for lack of funding and other reasons. Nearly half of California’s stream gauges are dormant.
This 25-minute documentary-style DVD, developed in partnership
with the California Department of Water Resources, provides an
excellent overview of climate change and how it is already
affecting California. The DVD also explains what scientists
anticipate in the future related to sea level rise and
precipitation/runoff changes and explores the efforts that are
underway to plan and adapt to climate.

Our 24×36-inch California Water Map is widely known for being the
definitive poster that shows the integral role water plays in the
state. On this updated version, it is easier to see California’s
natural waterways and man-made reservoirs and aqueducts
– including federally, state and locally funded
projects – the wild and scenic rivers system, and
natural lakes. The map features beautiful photos of
California’s natural environment, rivers, water projects,
wildlife, and urban and agricultural uses and the
text focuses on key issues: water supply, water use, water
projects, the Delta, wild and scenic rivers and the Colorado
River.
The Russian River is one of the major northern streams that drain
the sparsely populated, forested coastal area that stretches from
San Francisco to the Oregon border.
Other North Coast waterways include the Klamath, Trinity, Eel and
Smith [see also North
Coast Rivers]. These rivers and their tributaries flow west
to the Pacific Ocean and account for about 40 percent of the
state’s total runoff.
Travel most anywhere in California and there is a river, creek or
stream nearby. Some are highly noticeable and are an integral
part of the community. Others are more obscure, with intermittent
flows or enclosed by boxed concrete flood channels that conceal
their true appearance. No matter the location, each area shares
some common themes: cooperation and conflict regarding water
allocations, greater water conservation, an awareness of
environmental stewardship, and plans that ensure long-term
sustainability.
This printed issue of Western Water examines the Russian and
Santa Ana rivers – areas with ongoing issues not dissimilar to
the rest of the state – managing supplies within a lingering
drought, improving water quality and revitalizing and restoring
the vestiges of the native past.
