Blue-green algae-related toxin warnings remain at Russian River beaches 

Mary Callahan, THE PRESS DEMOCRAT

The Russian River tested clean this week for a toxin related to blue-green algae that prompted cautionary signs at 10 popular beaches last month and in each of the past two summers.

The river remains open to swimming and other recreation. But warning signs urging visitors to avoid ingesting river water will remain at 10 popular beaches between Cloverdale and the river mouth as a precaution against exposure to the neurotoxin involved, the Sonoma County Department of Health Services said.

The weekly sampling suggests the threat, already minimal, could be diminishing. But precautions can only be lifted after several weeks pass without detection of the neurotoxin called anatoxin-a, county health personnel said.

Sonoma County issues toxic algae warning for Russian River beaches

Sonoma County provides more information on blue-green algae at its website here

Sonoma County officials posted caution signs at beaches up and down the Russian River on Wednesday alerting visitors to positive test results for a potentially dangerous, naturally occurring neurotoxin linked to harmful algae, a problem surfacing around Northern California this summer.

Water samples collected at three local beaches turned up very low levels of a substance called Anatoxin-a, which is produced by certain species of blue-green algae, Sonoma County health officials said.

It’s the third year in a row the algae-related toxin has been detected in the river.

The most-recent samples were taken Monday and the test results received Wednesday, Sonoma County Health Officer Karen Milman said.

Though the level of toxin in the water “was just at the ability to detect it,” the finding triggers precautionary alerts under state guidelines, she said.

Rivergoers should be particularly watchful of dogs, which are actually attracted to harmful algae, according to studies, and, by virtue of their relative body size and habits when around fresh water, are particularly susceptible to exposure.

Crews break through blockage to reopen river

Frank Robertson, SONOMA WEST TIMES & NEWS

High surf conditions closed the mouth of the Russian River at Jenner for about a week before Sonoma County Water Agency crews dug a channel that biologists hope will balance the interests of the river’s endangered native salmon and steelhead trout along with flood prevention.

On July 17, the Water Agency opened an outlet channel on the beach at Goat Rock State Park appears to be working this week.“ The goal of the outlet channel is to enhance habitat for federally listed juvenile salmon and minimizing flood risks by keeping freshwater levels in the estuary while allowing river water to flow out of the estuary and prevent ocean water from entering,” said Water Agency spokesperson Ann DuBay.

She said the Water Agency will monitor conditions at the estuary and manage the lagoon’s depth this summer so that high water doesn’t flood low-lying areas in Jenner such as the visitor center on Highway 1.

Ideally the outlet channel would remain in place until mid-October to maintain the estuary lagoon.

The Water Agency is conferring with the National Marine Fisheries Service (NMFS), the state Department of Fish and Wildlife and other agencies to discuss an appropriate outlet channel and lagoon management strategy, said DuBay.

The Water Agency has been trying, with limited success, to maintain a summer lagoon since 2008 when NMFS issued a biological opinion that ordered changes in the agency’s Russian River operations.

Since the biological opinion was issued calling for the Water Agency to maintain a closed summer estuary if and when the Jenner sandbar closes naturally, a maintenance plan has been implemented three times, said Water Agency Environmental Resources Manager Jessica Martini-Lamb.

Russian River beach still closed; officials search for cause of high bacteria levels 

Mary Callahan, THE PRESS DEMOCRAT

Inquiries and inspections have been made about septic tanks, porta-potty operations and homeless encampments as well, in an effort to narrow down the cause, ….

Updates on the status of the beach are available at sonomacounty.ca.gov/Health/Environmental-Health/Water-Quality/Fresh-Water-Quality/.

Monte Rio Beach will remain closed to swimming for at least one more day as public officials continue to pursue the reason for elevated lab tests that indicate contamination of the water with harmful bacteria, the Sonoma County Department of Health Services reported Monday.

The decision to keep beach-goers out of that stretch of the Russian River through at least Tuesday extends the ongoing beach closure to a fifth day, though officials have yet to confirm or pinpoint any specific hazard or source of pollution.

But state guidelines governing water quality required the closure last week because of test results above the state-allowed threshold for two indicator bacteria considered markers for possible fecal contamination. The beach status is now considered day-to-day.

The latest round of testing put total coliform bacteria at 11,199 organisms per 100 milliliters of sampled water collected off the beach Sunday, Deputy County Health Officer Karen Holbrook said. The state standard is 10,000 organisms per 100 ml.E. coli was measured at 149 organisms per 100 milliliters in samples taken Sunday. The state standard is 235 per 100 ml.E. coli levels dropped below the safety threshold July 6 and appear to have stayed there, though they remain above the two-digit numbers typical of routine testing at 10 Russian River beaches conducted by the county.

The highest test result in the past week put the E. coli level at 833 organisms per 100 ml. or almost four times the state standard, possibly as a result of huge crowds at the beach over the July Fourth weekend.

Dams be damned: California rebuilds the salmon habitat it destroyed

Monica Heger, YES! Magazine, for TRUTHOUT

A consequence of the creek being confined to its channel is that, over years, the water has dug away at the creek bed — or substrate — making it deeper and narrower, and increasing the speed at which water flows. This has decreased the chances that water will spill over the banks. The larger substrate materials that made the creek bed stable — boulders, gravel, and logs — have been washed out, but are not being replaced. Instead, the creek bed is becoming ever finer and more prone to being further incised. In this environment, salmon eggs are more likely to be washed away.

Wander out the back door of the tasting room at Truett Hurst Winery in Sonoma County, California, and follow the dirt path to the red Adirondack chairs next to Dry Creek. Look just downstream to the side channel that splits off the main waterway. You will see sets of interwoven logs and overturned trees with roots that splay along the banks. These aren’t the result of a particularly rough storm — they are there by design. As Dry Creek rushes by, these logs and root beds point the way to a newly excavated side channel — prime habitat for spawning and juvenile salmon.

In freshwater waterways along the coast from Marin to Mendocino counties, agencies are restoring salmonid streams to create habitat diversity, areas that provide deep pooling, predator protection, and side channels of slower-moving water. California salmon are in dire straits. Decades of dam building and development have destroyed or altered salmon habitat, eliminating the diversity of habitat these fish need.

As a result, salmon populations have plummeted. The number of coho salmon that return to the California waterways from the Pacific Ocean each year has dropped from around 350,000 in the 1940s to less than 500 in 2009. Although they’ve rebounded slightly, numbers are still 90 percent to 99 percent below historic levels, and many scientists are worried that California’s historic five-year drought followed by an exceptionally rainy winter could wreak further havoc.

Salmon provide enormous environmental and economic benefits. They are an integral component of marine and freshwater foodwebs and play a role in transporting nutrients from the ocean into rivers. In California, salmon are the backbone of a $1.5 billion commercial and recreational fishing industry.

The Warm Springs Dam, which crosses Dry Creek, is one of two drinking water sources for around 600,000 customers in Sonoma County, but the year-round flows it produces are a problem for salmon.

“Dry Creek is a tremendous misnomer,” says David Manning, environmental resources manager at the Sonoma County Water Agency. “It flows so quickly that it doesn’t provide habitat for steelhead and coho,” and young fish are often washed downstream. To combat this, Manning and others are building “off-ramps” that will allow salmon to exit the Dry Creek freeway.

New report says California’s ‘iconic’ native fish facing extinction in 50 years

Guy Kovner, THE PRESS DEMOCRAT

The “Fish in Hot Water” report includes a road map for addressing the threats to California’s native fish, including restoration and protection of critical habitats, such as spring-fed rivers, flood plains and estuaries as well as river system headwaters.

Read the report here: http://www.caltrout.org/sos

On a tree-shaded bend in Dutch Bill Creek at Monte Rio, three technicians from the Sonoma County Water Agency huddled on a gravel bar to examine the day’s catch, all in the name of science and a sustained campaign to restore one of California’s most endangered fish.

Retrieving 163 coho salmon smolts, or young fish, from a wooden fish trap set in knee-deep, clear flowing water, the crew bathed the four- to six-inch salmon in a bucket of Alka-Seltzer solution, briefly numbing them for easier handling.

The technicians measured, weighed and counted the year-old, hatchery-bred fish before releasing them to continue a perilous journey to the nearby Russian River and out to the Pacific Ocean.

If the young coho, swimming mostly by night to evade predators, make it to the ocean and grow to adulthood, they may in about 18 months return to the Russian River and be counted once again before they spawn and die.

There’s a lot riding on the coho completing their short, human-assisted life cycle.Nearly half of California’s native salmon, steelhead and trout — 14 out of 31 species — are facing extinction in 50 years under current conditions, according to a scientific study released last week.

Another nine species are likely to vanish in 100 years unless steps are taken to address threats such as low water flows, pollution, urban growth, dams and degraded habitat, exacerbated by the recent drought and climate change, the 106-page report by the conservation nonprofit California Trout and the UC Davis Center for Watershed Sciences said.

Fate of Russian and Eel River flows rests in big fight over small hydroelectric project

Guy Kovner, THE PRESS DEMOCRAT

Even the record rainfall that dowsed the North Coast this winter, filling reservoirs and streams, will not be enough to head off a looming clash over the water that courses down two of the region’s largest rivers, the Russian and the Eel.

Together, they drain a swath of territory, including cities, forests and vineyards, that stretches from central Sonoma County to Fortuna, in Humboldt County — an area larger than Connecticut.

A key link between the two rivers, a small powerhouse more than 100 years old, is now the focal point in a fight over the water that flows down these rivers. It’s a standoff with many of the main players in western water wars — farmers, environmentalists, water districts serving urban customers and fishermen. And it raises many of the same questions: Who benefits and who loses from water taken for decades from one river — at over 20 billion gallons a year — and funneled into another river?

In this case, it is the Eel River that has been tapped, its water sent down a milelong tunnel through a mountain in Mendocino County, into a PG&E powerhouse and ultimately into a fork of Russian River, which flows down through Sonoma County.

Water drawn from the Eel River sustains Lake Mendocino, the main source of drinking water for residents along the Russian River from Redwood Valley down to Healdsburg.

Turning off that supply could devastate agriculture and diminish that primary water source for thousands of people, according to interests on one side of the tug-of-war.

The vast majority of the more 600,000 North Bay residents who depend on the Russian River for drinking water are unaware of the plumbing arrangement and the controversy that has long swirled around it and two related dams on the Eel River, where once-prolific runs of salmon and steelhead trout have dwindled amid various human impacts, water diversion among them.

But for the partisans — the water managers, environmentalists, public officials, ranchers and scientists — the dilemma of parsing out this water between competing interests, between people and fish, between town and country, is revving up again over the relicensing of the PG&E powerhouse, called the Pottery Valley Project.

“It’s a critical moment,” said Rep. Jared Huffman, the San Rafael Democrat whose North Coast district spans the adjacent watersheds.

Russian River’s future draws diverse crowd to conference

Guy Kovner, THE PRESS DEMOCRAT

The supervisor’s goal in drawing together diverse interests from the public, private and nonprofit sectors is to “drive toward creating a one-watershed plan,” he said.

Environmentalists, bureaucrats, public officials, Native Americans and a patron of the arts gathered Friday to plot a future for the Russian River, the waterway they all consider a foundation for communities throughout the North Bay.

The river, which snakes 110 miles from the Mendocino County highlands near Willits to the Pacific Ocean at Jenner in Sonoma County, is a magnet for boaters, bird-watchers, swimmers and anglers, a water supply for 600,000 North Bay residents and the main artery of a 1,500-square-mile watershed.

It also faces a host of challenges over poor water quality and competing demands to support endangered fish, tourism, water storage, flood control and human needs ranging from raw thirst to pure inspiration.

Sonoma County Supervisor James Gore convened the Russian River Confluence, which drew about 220 people Friday to Santa Rosa Junior College’s Shone Farm, located about 2 miles east of the river in the Forestville area.

Russian River “Low Flow E.I.R.” 

RUSSIAN RIVERKEEPER

In 2003 Riverkeeper engaged residents and activists in the Lower Russian River when the public learned about plans to drop the summer flows in the river by up to 80%.

In 2008, the Russian River Biological Opinion (RRBO) was approved by NOAA Fisheries in order to mitigate negative impacts from the operation of the two Army Corps dams, water supply operations and flood control activities. The RRBO section titled “reasonable and prudent alternatives” stated that salmon would benefit if we cut summer flows by 70% in an attempt to improve estuary conditions for juvenile salmon by maintaining a closed estuary. The rationale was that lower flows would help maintain a closed estuary but over the last several years it is clear that goal will be difficult to meet due to natural ocean conditions.

At that time, Riverkeeper stated that cutting flows would increase nutrient concentrations and end up harming juvenile salmon in the estuary by growing too much algae, which affects dissolved oxygen levels. Fast forward to last summer and we had flows in the 70 cubic feet per second range that is close to the proposed 70% reduction and we had our first ever toxic algae outbreak that killed at least two dogs.

At the same time, our understanding of fish population dynamics supported by many fishery biologists is that food production in the river above the estuary would be negatively affected by cutting flows by up to 70%.

The Draft EIR was released from the Sonoma County Water Agency in mid-August. Read the EIR here.

Russian Riverkeeper is concerned with likely water quality problems if flows are allowed to stay below 100cfs throughout the summer months. One of our goals is to ensure water saved from reduced flows is not put up for sale but reserved to mitigate potential water quality impacts.

The comment period for this Draft EIR ended on Friday, March 10.  The Sonoma County Water Agency now will read all the comments and questions, and will reply to all of them.  They hope to have the Final EIR done by the end of 2017.  Then it goes to the State Water Resources Control Board for final approval.

Russian River Fish Flow Project EIR public review extended

SONOMA COUNTY GAZETTE

The DEIR and the errata sheet are available online at http://www.scwa.ca.gov/fish-flow/.

The Sonoma County Water Agency has extended the public review period for the Fish Habitat Flow and Water Rights Project (Fish Flow Project) Draft Environmental Impact Report (DEIR) to 5 p.m., March 10, 2017. The 204-day review period began on August 19, 2016.

The comment period was extended to allow for additional time to review a recently released errata. The errata was issued after resource agency staff asked a question about a specific water temperature figure in Appendix G to the DEIR, which resulted in Water Agency staff reviewing the figures again. The errata corrects temperature and dissolved oxygen figures in the appendix of the modeling results. The errata does not change the DEIR impact analysis. The DEIR errata do not add significant new information or data regarding the project or environmental setting and would not substantially increase the severity of an impact or create a new significant impact.

“Because there are a large number of pages in the errata, we felt it was appropriate to provide agencies and the public with additional time,” said Water Agency Environmental Resources Manager Jessica Martini-Lamb. “By extending the comment period end date to March 10, we are providing people more than a month to review the errata.”

The Fish Flow Project would lower minimum instream flow requirements in the Russian River and Dry Creek to benefit threatened and endangered juvenile salmon, change the hydrologic index to better reflect watershed conditions and secure the existing rights to 75,000 acre feet of water used to provide drinking water to 600,000 residents in portions of Sonoma and Marin counties. The DEIR describes the proposed Fish Flow Project, the purpose of the project, why it is necessary and the potential environmental impacts of the project.

The DEIR and the errata sheet are available online at http://www.scwa.ca.gov/fish-flow/ and at Sonoma and Mendocino County libraries. Hard copies of the DEIR are available for purchase at (707) 547-1900 or at the Water Agency’s administrative office.  All written comments can be sent to fishflow-eir@scwa.ca.gov or to Sonoma County Water Agency, Attn: Fish Flow DEIR., 404 Aviation Boulevard, Santa Rosa, CA 95403 by 5 p.m., Monday, March 10, 2017.
