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.
With groundwater levels lower than normal after two years of
drought, Sonoma County and state officials are recommending
private well owners test their water for natural contamination.
“Well owners should test their well water to ensure it is safe
to consume,” Christine Sosko, county director of environmental
health, said in a news release. Shrinking aquifers that caused
some wells to run dry last year may have increased
concentrations of substances that “can be harmful to human
health,” Sosko said.
Amid two years of drought, Sonoma County and water quality
agencies released tools for well owners on Friday to ensure
their water is safe to drink. Private wells may have higher
concentrations of naturally occurring but harmful substances as
groundwater tables are lower than normal in some areas of
Sonoma County, according to Christine Sosko, the county’s
director of Environmental Health. … Sonoma County is home to
an estimated 45,000 water wells, and to keep them at a safe
drinking standard, owners have to consider the well’s location,
construction, maintenance and the lithology of its aquifer,
along with the amount of rainfall the area receives.
A group of studies released last month paint a clearer picture
of how Sonoma and Mendocino counties can meet future water
needs while reducing environmental impacts in the face of a
decision by PG&E to cease operation of an aging
hydroelectric power project. The Potter Valley Project (PVP) is
located approximately 15 miles north of the City of Ukiah on
the Eel River. The Project’s facilities include two dams, a
diversion tunnel and a hydroelectric plant located in Potter
Valley in the headwaters of the Russian River.
The future of a little-known dam on the Eel River in Lake
County may be shaped this year as the license expires on a
broken-down PG&E hydropower project that plays a critical
role in providing water to 600,000 Sonoma and Marin county
residents. Demolition of Scott Dam, a 138-foot concrete
structure built a century ago to impound Lake Pillsbury, is an
“absolute requirement” for a coalition that includes Sonoma,
Mendocino and Humboldt counties interested in picking up the
license, said Rep. Jared Huffman, the North Coast
congressman.
Development of a $1 billion resort and housing project in one
of the state’s most wildfire-prone communities has been placed
on hold after a judge ruled developers didn’t adequately plan
for what might happen when a wildfire erupts and thousands of
people have to run for their lives. The Lake County judge’s
ruling on the Guenoc Valley Resort could have sweeping
ramifications for housing and business developments across a
state where fires are growing in severity and local officials
are under intense pressure to approve new building projects
during a housing crisis.
December brought significant snowpack to the Sierra, breaking
records set in the 1970s. But areas like Mendocino and Sonoma
are still showing severe drought conditions, and our state’s
reservoirs have a long way to go to recover from last year’s
historic lows. … The city of Ukiah recognized years
ago that investing would be critical for ensuring a reliable
water supply, given our region’s dependence on the Russian
River and increasing drought conditions. In addition to
implementing conservation measures for business and residential
properties, we shifted emphasis to recycled water supplies and
groundwater.

the city of Ukiah.
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.
