Folsom Lake Level Far Ahead of Last Year

Folsom Lake level continues to rise.

Per the California Department of Water Resources, as of November 27, the lake stands at approximately 447,000 acre feet, about 3 times as much as last year at this time.

Although it is still 5% below the average for this time of year, note that usually we’re still losing water, with levels decreasing through late December. This year, the level has been growing since mid-October.

Gigantic Spike-Toothed Salmon Swam In California Rivers 5M Years Ago

At 400 pounds and 8 feet long, this salmon would be good eating—if only it wasn’t extinct. Oncorhynchus rastrosus, the giant spike-toothed salmon, lived in California for around 7 million years, going extinct 5 million years ago. This monster salmon, which is closely related to modern Pacific salmon and actually a member of the same genus, luckily left behind clues about its life and behaviors in its fossil remains. New research by paleontologist Julia Sankey at California State University Stanislaus and colleagues in PaleoBiosgets to the bottom of how this behemoth lived and bred.

Spike-teeth or saber-teeth? When this salmon species was first described, researchers called it a “sabertooth salmon” because of the long, robust teeth on its upper jaw, but actually they point outward instead of downward. This makes them more spike-teeth rather than sabers. The teeth were around 1.5 inches long and pointed straight out from the top of the jaw– likely used for breeding, digging and fighting. Living Pacific salmon fight with each other during mating season for the breeding rights to females, but did O. rastrosus do the same?

Why are salmon dying? (Hint: It’s a good thing…)

Dead salmon are washing up on banks of the American River. It sounds gruesome but it’s actually a good thing.
The annual salmon run is underway and the fish have traveled thousands of miles to spawn then die in our waterways.
“Within the last decade we have seen a downward trend,” said Department of Fish and Wildlife researcher Jeana Phillips. The DFW keeps a close eye on the salmon population. Every year a team of researchers count dead salmon after they have spawned.
The American River Nimbus Fish Hatchery in Rancho Cordova is full of salmon right now. A number of salmon in the American River were released from the Nimbus Fish Hatchery. Salmon hatch in rivers then make their way to the ocean where they spend 3 to 4 years. When they are ready to breed. Salmon leave the ocean, head back to the area they were born, lay eggs, then die.

Speed Limit Lifted As Folsom Lake Levels Rise Above 400 Feet

There was a little more action on Folsom Lake on Wednesday as motorboats were allowed to pick up speed once again on the water.

It’s been almost three months since the California Department of Parks and Recreation imposed a 5-mile-per-hour speed restriction for boaters on Folsom Lake. The lake level was too low to safely boat at higher speeds.

Alex Vitner frequents the lake and said, “I come frequently and it used to be a wide river, now it’s slowly filling the beaches and the sand is becoming beach again.”

This is definitely a welcome sight for drought stricken California. The National Weather Service recorded over a foot and a half of rainfall across northern California in the month of October. This helped to bring the Folsom Lake level up to 400 feet. That’s the magic number to bring down the speed restrictions on the lake, Higher water levels cover the hazards that pop up when the low water level falls below 400 feet.

The lake didn’t reach this level in the last rain season until late January.

Folsom, Granite Bay among those called out for dramatic increase in water use

Californians are continuing to use more water, state drought regulators said Tuesday, with residents of Folsom and Granite Bay among those who’ve ramped up their consumption the most.

The State Water Resources Control Board announced that urban consumption grew by 8 percent in September compared with a year ago. It was the fourth straight month of higher consumption now that strict conservation mandates have been relaxed. Water districts used about 170 billion gallons of water, an increase of 13 billion gallons compared with September 2015, the agency said.

In its announcement, the state board pointed to six urban agencies that experienced “sharp reductions in conservation,” including two in Greater Sacramento – the city of Folsom and the San Juan Water District. Folsom’s usage rose 25 percent in September compared with a year ago. Consumption in the San Juan district, which includes Granite Bay, grew by 29 percent. By contrast, consumption in the city of Sacramento grew by 8 percent, matching the statewide average.

Californians managed to conserve 18.3 percent in September compared with 2013, the baseline established by state officials. But a year ago, when statewide conservation regulations were in place, the savings rate was a more robust 26.2 percent.

“Overall, we’re happy to see millions of Californians and many water agencies continue significant conservation,” said board Chairwoman Felicia Marcus in a prepared statement. “Conversely, we’re concerned to see some agencies return to using hundreds of gallons per person per day while saving little. … We need to keep conserving.”

Nimbus Hatchery Fish Ladder to Open Nov. 2

The salmon ladder at Nimbus Hatchery in Rancho Cordova will open Wednesday, Nov. 2, signaling the start of the spawning season on the American River. California Department of Fish and Wildlife (CDFW) hatchery workers will open the ladder gates at 10:45 a.m. Hatchery employees may take more than a half-million eggs during the first week of operation alone in an effort to ensure the successful spawning of the returning fall run Chinook salmon.

There are eight state-run salmon and steelhead hatcheries, all of which will participate in the salmon spawning effort. Over the next two months, the three major state-run hatcheries in the Central Valley – the Nimbus Hatchery in Sacramento County, the Feather River Hatchery in Butte County and the Mokelumne River Hatchery in San Joaquin County – will take approximately 24 million eggs in order to produce Chinook salmon for release next spring.

Sacramento water agencies work together, adapting to drought

Dr. Jay Lund, director of the UC Davis Center for Watershed Sciences, is the godfather of research on the Sacramento-San Joaquin Delta. When he says it took John Sutter eight days to wind his way from San Francisco Bay through the Delta to find the narrow Sacramento River in 1839, you can bet that’s the truth. Not until 1913 was the mouth of the river dredged to make it a mile wide. Grizzly bears roamed the wildness, feasting on an abundance of native fish, until they were hunted to local extinction. Today in the Delta, the largest estuary on the west coast of North America, only remnants remain of the natural landscape before it was irreversibly altered at the hands of people.

The Delta is a system of canals. In places, you can stand on a man-made levee with high water on one side and sunken land on the other. For 7,000 years, sediment accumulated to form deposits of organically-rich peat soil, but the last 170 years of farming have undone this natural process. About 2,300 dump trucks worth of soil is lost per day, oxidized as carbon dioxide and all told, about half of the Delta’s soil material is now gone, says Curt Schmutte, a civil engineer who specializes in Delta issues. We named plots of land in the Delta “islands,” but scientists refer to them — the majority below sea level — as “holes.”

I’m with a tour group on a hot September afternoon, and we hold onto our hats and brace ourselves as the boat tears through the water at 40 miles per hour, past invasive water hyacinth, tules, fishermen, houseboats, farmland and cattle. The Delta accumulates water from California’s largest watershed and acts as the hub of the state’s water supply system, linking water from the north to the two biggest water projects, which play a major role in sustaining the world’s sixth largest economy and much of its industry, agriculture and 39 million people.

But the Delta exists under unrelenting pressure: from land-use change, population growth, nutrient pollution from wastewater treatment plants, earthquakes, agriculture, sea-level rise and more. Even with money, there’s no silver bullet to fix this ecosystem — but there are plenty of battling sides. “It’s like a game of chicken,” Lund says. “How do you break a game of chicken?”

Was it Mark Twain who proclaimed, “Whiskey is for drinking; water is for fighting over”? When it comes to this natural resource, our state is rife with conflict. And, perhaps, in the Sacramento region, open to resolution. While the state is all-consumed with water wars, the region’s efforts toward collaboration are easy to overlook. The best example is the landmark Water Forum Agreement, which 22 water agencies from Sacramento, El Dorado and Placer counties signed in 2000 to balance the environmental and human needs of the lower American River.

Now, water agencies have joined together again to launch the River Arc Project. Proponents say the project has the potential for a groundbreaking impact. It would help recharge groundwater through a management practice called “conjunctive use.” It would also allow for ongoing growth by creating an additional source of water to lessen demand on the lower American River and Folsom Lake, which already provide drinking water to 1 million residents, says Andy Fecko, director of resource development at Placer County Water Agency. “What’s unique about our region is we’re doing this before we have a crisis.”

How a beer maker and a bottled water company want to save Sierra forests

California’s forests are in crisis. A lethal combination of drought, wildfires, warmer temperatures and pests has destroyed 66 million trees in the past six years.

Restoring our forests won’t be easy. Gov. Jerry Brown and the Legislature recognized the importance and magnitude of the task by allocating $40 million in cap-and-trade funds. At the same time, President Barack Obama visited Lake Tahoe to announce $29.5 million to improve forest health and decrease the threat of catastrophic wildfires.

They’re prioritizing these investments because they know that California’s forests are critical to our water supply. Forests help reduce erosion and recharge aquifers.

Government funding is vital, but it’s not enough. We need innovative thinking and support from private partners with resources and expertise, such as a recently launched effort in the Sierra Nevada, one of the most important sources of water for drought-stricken California.

12 tons of trash pulled in Great Sierra River Cleanup

More than one thousand volunteers in the Sierra Nevada Region helped pull 12 tons of trash from rivers, lakes, and streams on Saturday.

The event was all a part of the 8th annual Great Sierra River Cleanup.

Estefan Galvan, 25, is a diver with seven years experience who helped cleanup Saturday.

“Diving is a whole different world. It’s an entirely different world,” Galvan said. “When you get under water it’s a completely different feel, your away from everything at the surface.”

Galvan joined a crew of a dozen divers in Folsom, California who pulled several items from the American River.

“Our main focus is going to be under the cliff diving spots and under the bridges where people tend to be looking over the edges or jumping off or throwing things over,” Galvan said.

The group pulled a bicycle, fishing rod, cans, glass, anchors and more from the American River.
