Lightning strikes cause fires, concern for Cal Fire

A wave of lightning strikes swept across parts of Northern California Thursday, touching off flames and causing concern more fires could erupt as temperatures warm next week.

“We’ve had over 500 lightning strikes in Northern California in the last six hours,” Cal Fire spokesman Brice Bennett said early Thursday evening, as dispatchers monitored lightning strikes at the Amador-El Dorado Unit’s joint operations center in Camino.

“Butte’s had a couple strikes and the fire has actually grown to over 20 acres,” Bennett added.

The biggest concern is that strike-caused fires would keep burning, even as rain continues to fall.

“So, we’re seeing lightning-sparked fires, with rain, grow. And that’s a cause of concern for us,” Bennett said. “Some of the units in Northern California have activated their lightning plan due to the number of strikes and the fires they are finding from these strikes.”

Up the South Fork of the American River to the east, camper Rebekah Huitema recalled the arrival of thunder and lightning there.

“I screamed like a little girl,” Huitema said. “It was right here. You could almost feel the pulse from it.”

Scientists find a way to reduce mercury in wetlands

Scientists have found new ways to reduce mercury in wetlands, providing hope that Sacramento-area waterways can be decontaminated of the potentially toxic element that dates back to Gold Rush-era mining activities.

The new research, published recently in Environmental Science and Technology, found that dosing wetlands with two chemicals, iron or aluminum salts, was successful in removing mercury from wetlands.

Researchers spent two years on the project and built nine wetlands on public land in the Sacramento-San Joaquin Delta at Twitchell Island. They applied water with aluminum salts to three wetlands, water with iron to another three and regular water to the last set of three, according to Tamara Kraus, a research soil scientist with the U.S. Geological Survey and a co-author of the study.

To determine the effects, researchers introduced mosquitofish. They found mercury levels in the mosquitofish decreased by 62 percent in wetlands dosed with aluminum salts and by 76 percent in wetlands where iron was used.

The mercury lingering in area rivers, creeks and wetlands dates back to the 19th century, when miners used the element to help extract gold in the Sierra Nevada foothills.

Controlling mercury levels in area rivers, creeks and wetlands is a key health issue because many people continue to eat fish they catch from mercury-contaminated waters, despite advisories.

“The mercury levels are of concern to us because people are still fishing regularly out of the Delta,” said Sonney Chong, chairman of Capital, an umbrella organization representing the Asian American and Pacific Islander community.

A 2013 assessment by the California Department of Public Health found that Hmong, Laotian and Cambodian residents are avid fishermen in the Delta, but that some have low awareness of the mercury issue.

“They’re feeding their family. It’s an outright source of food, so they’ve ignored the advisories,” Chong said.

Ingestion of mercury can lead to problems that include mental impairment and other developmental abnormalities, especially in fetuses and young children.

Mercury bioaccumulates in fish tissue and is passed up the food chain in greater quantities as larger fish eat small fish.

In 2011, a survey of 16 species of sport fish from 63 locations done by the State Water Resources Control Board found that fish caught in the Sacramento-San Joaquin Delta watershed had higher concentrations of mercury than anywhere else in the state. The highest contamination was in fish high up the food chain – smallmouth and largemouth bass, striped bass and the Sacramento pikeminnow.

Contaminated river sites included the American River at Discovery Park and the south fork of the American River at Coloma. Fish tested from the San Joaquin River pier at Point Antioch and at Louis Park in Stockton also showed high mercury levels.

Illegal camping sparks concerns about fires along American River Parkway

Pressure is mounting for Sacramento County to do more about illegal camping and potential fire danger along the American River Parkway.

“Move the homeless population out of the 12th Street corridor,” said Mike Rushford of the American River Parkway Preservation Society.

Rushford was inspecting the charred-out remains of a fire in Sacramento’s urban forest, the American River Parkway.

Illegal homeless campsites “threaten this big open preserve here,” Rushford said.

“A month from now, this would just burn all the way to the Woodlake area,” Rushford said. “This year, because it’s the fourth year of a very bad drought, could be the year that we get that catastrophic fire that we all fear so much.”

Preservationists like Rushford are increasingly concerned about illegal campsites and the growing risk of fires caused by transients.

Last year a KCRA 3 investigation revealed the Sacramento Fire Department fought 85 fires over a four-mile stretch along the American River between Discovery Park and Cal Expo.

On Tuesday along the American River Parkway, KCRA 3 discovered a wide array of tents, camping gear and even barbecue grills in open display.

Sacramento County park rangers on patrol told one illegal camper to move out. “I just got here,” said the homeless man.

Park rangers last year discovered more than 1,100 illegal campsites and issued 756 citations.

Water release from Folsom Lake designed to help Delta

The Bureau of Reclamation increased water flows from Folsom Dam early Wednesday morning.

The wind, tides and lack of water in the Delta have become a concern for the Bureau.

“All of those things have come to a head right now and there are salinity issues in the Delta that need to be managed by increasing the releases out of Folsom,” said Erin Curtis, the spokesperson for the Bureau’s Mid-Pacific Region. “The important place to make the releases right now is Folsom.”

The Bureau increased the flow from 1,250 cubic feet per second (CFS) to 1,500 CFS.

By releasing more water from Folsom Lake into the river system, the river has a better ability to keep the salinity out of the Delta.

But the increased flows mean Folsom Lake is dropping fast.

A Short Run for Some California Whitewater Rivers This Season

Justin Butchert drops bags of ice into huge coolers and lifts them onto his pickup truck.

“This is our only form of refrigeration up there,” says Butchert, owner of Kings River Expeditions.

He’s referring to his company’s base camp on the Kings River, east of Fresno in the Sierra Nevada. The outfit has run overnight trips, complete with cookouts and goofy campfire skits, for more than 30 years.

But this is the first time in 25 years he’s packed the food.

“You know I just do everything now,” he says. “We used to have a full staff doing this and we don’t have that anymore.”

He has the same number of employees, but they’re working fewer hours. In the best of years, his company stays open until Sept. 1 and guides about 6,000 folks down miles of roaring rapids.

American River Parkway Spring Clean Up Is Set For This Saturday

There’s still time to volunteer to work at The Annual American River Parkway Spring Clean Up.

For the 9th year in a row, a spring clean-up of the 23-mile American River Parkway will happen this Saturday, April 11.

“With the water levels so low we have access to so much of the riverbed where so much trash is and if we can help remove that when it does rain and we get a normal precipitation the waterways will not be dirty.”-Dianna Poggetto with the American River Parkway Foundation says.

Poggetto says it goes from 9 to Noon and they’ll provide food and water:

Governor Issues Mandatory Water Cuts As California Snowpack Hits Record Low

Standing in a dry brown meadow that typically would be buried in snow this time of year, Gov. Jerry Brown on Wednesday ordered the first mandatory water cutbacks in California history, a directive that will affect cities and towns statewide.

With new measurements showing the state’s mountain snowpack at a record low, officials said California’s drought is entering uncharted territory and certain to extend into a fourth straight year. As a result, Brown issued sweeping new directives to reduce water consumption by state residents, including a mandatory 25 percent cut in urban water use.

On Wednesday, Brown attended a routine snow survey at 6,800 feet in the Sierra Nevada, near Echo Summit on Highway 50 along the road to Lake Tahoe. The April 1 survey is an annual ritual, marking the end of the winter season, in which automated sensors and technicians in the field strive to measure how much water the state’s farms and cities will receive from snowmelt.

The measurements showed the snowpack at just 5 percent of average for April 1, well below the previous record low of 25 percent, which was reached last year and in 1977.

California’s mountain snowpack is crucial to determining summer supplies, normally accounting for at least 30 percent of total fresh water available statewide. The poor snowpack means California reservoirs likely already have reached peak storage and will receive little additional runoff from snowmelt, an unusual situation.

“We’re standing on dry grass, and we should be standing in five feet of snow,” Brown said. “We’re in an historic drought, and that demands unprecedented action.”

Brown’s executive order directs California’s more than 3,000 urban water providers to collectively cut their water use by 25 percent compared with 2013. The State Water Resources Control Board is expected to impose the new restrictions by mid-May, setting a different target for each agency depending on how much water its customers use per capita and conservation progress since last year.

American River Parkway Life Vest Stations Open Two Months Early

The Sacramento region’s current run of unseasonably warm weather has prompted the American River Parkway Foundation to launch its Kids Don’t Float life vest program two months early.

The foundation announced that it began providing life vest stations at several locations along the parkway Monday.

The Kids Don’t Float program allows individuals to borrow a life jacket while enjoying the Sacramento area’s waterways. In 2008, the Sacramento County Board of Supervisors adopted an ordinance requiring life preservers to access public waters within the county. The ordinance specifies that it is unlawful for parents to permit children younger than 13 years old to enter public waters unless the child is wearing a life preserver. Violation of the ordinance is punishable by a fine of $500 and/or six months in jail.

Drought Threatens American River Fish

Endangered steelhead about to hatch in the American River could soon be killed by low flows and warm temperatures caused by the drought, a sign of the ongoing struggle over scarce water supplies.

The fish, which are protected by the Endangered Species Act, are beginning to hatch from eggs in riverbed gravel. They require water cooler than 57 degrees to survive. Temperatures are already warmer than that due to record-breaking heat this month and low river flows caused by a fourth year of drought in California.

As hatchlings – also known as alevins – the fish have not yet matured into fully formed fish and are unable to swim.

“It’s the most sensitive life stage. They can’t go elsewhere and they’re highly sensitive to flows,” said Tom Gohring, executive director of the Sacramento Water Forum, a coalition of Sacramento water agencies and environmental groups that monitors the river. “If things continue to be bad … they will perish in the gravel.”

The problem is a shortage of water in Folsom Reservoir caused by the drought. Although the reservoir now holds more water than at this time last year, it is expected to be in worse shape by the end of summer.

That’s because the Sierra Nevada snowpack is at its lowest level in recorded history – just 8 percent of average as of Thursday. As a result, it will provide little runoff to refill the reservoir in the months ahead. Weather patterns diverted storms away from California most of the winter, leaving January and March as the driest in more than 100 years of record keeping.

The U.S. Bureau of Reclamation, which operates Folsom and Nimbus dams on the American River, dropped water flows in the river to 500 cubic feet per second on Thursday. That falls below a flow standard negotiated with the Water Forum to protect the river environment, but it is allowed in cases of severe drought, Gohring said.

“That was primarily an effort to help conserve water based on the persistent drought conditions,” said Reclamation spokesman Louis Moore. “Everything is being done to make sure the water supply we have is being used to the best of our ability, and we’re working with others to stretch it.”

Water stored in Folsom Reservoir serves a number of urban water suppliers in the Sacramento region, as well as farm irrigation districts in the San Joaquin Valley.

Reclamation has a limited ability to monitor temperatures in the river on its own. So the Sacramento Water Forum, which is funded mainly by local water agencies, hired a consultant to install temperature probes at strategic locations in the river. Those revealed that water temperatures have already exceeded 57 degrees, Gohring said.

The problem has been aggravated by record-breaking heat in the Sacramento area last week. On Friday, Sacramento Executive Airport saw a high of 83 degrees, breaking the previous record of 79 degrees set in 1986. Downtown reached 85 degrees, which tied the record from 1923.

Reclamation responded by boosting water releases from Folsom Dam. The water is being released from gates in the face of the dam – a rare occurrence – in order to access cold water deeper in the reservoir. That cooler water is expected to reach the lower American River, where steelhead spawn, starting Sundaymorning.

The additional water flows will be temporary, lasting only into the afternoon on Monday. But officials hope it will be enough to help the emerging steelhead. Sacramento temperatures are expected to cool down to a more seasonable 70-degree range on Tuesday.

“If water temperatures become a detriment to fish, they will make an adjustment to try and cool the water a bit,” Moore said. “We are conserving as much as we can, and every little bit counts.”

The tight scheduling of water flows indicates how precious supplies have become.
