Nutria Discovered in San Joaquin Valley; CDFW Seeks to Prevent Further Spread and Infestation

The California Department of Fish and Wildlife (CDFW) has become aware of a population of invasive nutria (Myocastor coypus) reproducing within the San Joaquin Valley. Given the severity of potential impacts and the impacts realized in other infested states, CDFW believes early intervention actions could be successful in eradicating nutria from the area and is asking the public’s help in looking for and reporting nutria sightings in order to determine the extent of the infestation.

To date, nutria have been found in wetlands, rivers, canals and other freshwater habitat in Merced, Fresno and Stanislaus counties. If allowed to establish, nutria will severely impact California’s resources, causing the loss of wetlands, severe soil erosion, damage to agricultural crops and levees and reduced stability of banks, dikes and roadbeds, as they have done in Louisiana, Chesapeake Bay and the Pacific Northwest. Nutria also degrade water quality and contaminate drinking supplies with parasites and diseases transmissible to humans, livestock and pets.

Native to South America, nutria are large, semi-aquatic rodents that reach up to 2.5 feet in body length, 12-inch tail length and 20 pounds in weight. Nutria strongly resemble native beaver and muskrat, but are distinguished by their round, sparsely haired tails and white whiskers (see CDFW’s Nutria Identification Guide). Both nutria and muskrat often have white muzzles, but muskrats have dark whiskers, nearly triangular (laterally compressed) tails and reach a maximum size of five pounds. Beavers have wide, flattened tails and dark whiskers and reach up to 60 pounds.

Female nutria are reproductive by six months of age, breed year-round, and can produce three litters in 13 months. Within approximately one year of reaching reproductive maturity, one female nutria can result in more than 200 offspring, which can disperse as far as 50 miles.

Nutria are destructive, wasteful feeders that destroy up to 10 times the vegetation they consume. Signs of presence typically include cut, emergent vegetation (e.g. cattails and bulrushes), with only the base portions eaten and the stems left floating. Nutria construct burrows with entrances typically below the water line, though changing water levels may reveal openings. Similar to other aquatic mammals, nutria often create runs, or paths in and out of the water or between aquatic sites. Nutria tracks have four visible front toes and, on their hind feet, webbing between four of five toes. Tracks are often accompanied by narrow tail drags.

Since March 30, 2017, more than 20 nutria, including males, pregnant females and juveniles, have been documented within private wetlands near Gustine, duck clubs, the Merced River near Cressey, adjacent to the San Joaquin River near Grayson, south of Dos Palos, the San Luis National Wildlife Refuge, and Salt Slough on the San Joaquin River. The full extent of the infestation is not yet known.

A multiagency Nutria Response Team, which includes representatives from CDFW, the California Departments of Food and Agriculture, Parks and Recreation, and Water Resources, the U.S. Department of Agriculture, the U.S. Fish and Wildlife Service and local county agricultural commissioner offices, has convened with the goal of eradicating nutria from the state. The response team is currently preparing an eradication plan, the first stage of which is determining the full extent of the infestation. Assistance from local landowners and the public throughout the Central Valley, Sacramento-San Joaquin Delta and beyond is critical to successfully delineating the population.

Suspected observations or potential signs of nutria should be photographed and immediately reported to CDFW’s Invasive Species Program online, by e-mail to invasives@wildlife.ca.gov, or by phone at (866) 440-9530. Observations on state or federal lands should be immediately reported to local agency staff at that land. CDFW has a nutria webpage and a downloadable PDF with photos and detailed descriptions of these rodents, their preferred habitat and the environmental threats they present.

It’s a brutal end for these salmon, but it replenishes oceans and feeds families

Thousands of salmon make the grueling journey from the Pacific Ocean up the American River each fall. The spawning run ends for many with a whack on the head at the Nimbus Fish Hatchery, where salmon eggs are gathered and fertilized.

The salmon would normally die a slow death after spawning. But at Nimbus, they’re quickly dispatched in a process viewed annually by hundreds of children and adults through big glass windows at the hatchery in Gold River.

What becomes of the dead salmon is less well known. While the ending isn’t happy for the adult fish, their offspring repopulate the oceans, and tens of thousands of pounds of salmon fillets feed hungry families in northern and central California during the winter months.

Folsom Lake and Lake Natoma had high E. coli readings

Environmental advocates are calling on state officials to notify the public about past tests showing high levels of E. coli in Folsom Lake and Lake Natoma, two of the region’s most popular areas for open water swimming and boating.

But officials responsible for recreational use on the lakes say the test results cited are too old, while the agency that conducted the tests says it has no responsibility for public notices.

The Central Valley Regional Water Quality Control Board in December concluded that the amount of E. coli in the lower American River had exceeded the federal threshold for safe recreational use. The test results didn’t become public until The Sacramento Bee reported them in late August.

The findings were based on water samples taken from 2007 to 2014. Some tests showed E. coli concentrations in Lake Natoma were eight times the level considered safe for recreational use by the U.S. Environmental Protection Agency.

A board report earlier this year found elevated E. coli levels in the lower American River in 2015 and 2016, but did not include samples from Lake Natoma and Folsom Lake, where tens of thousands of people swim, boat and fish every year. The board has limited funds for testing and wanted to focus on areas where higher levels had been found in the past, said Adam Laputz, assistant executive officer at the board. The highest concentrations have been near downtown Sacramento.

E. coli can sicken and even kill people who swim in or drink contaminated water. State and county officials have said they’re not aware of anyone getting sick from the bacteria in the American River.

Nimbus Hatchery Fish Ladder to Open Oct. 9

The Nimbus Hatchery Fish Ladder on the American River will open on Monday, Oct. 9 at 10:45 a.m. The ladder is opening unusually early in the season to accommodate the arrival of returning adult fall-run Chinook salmon that hatched in the Coleman National Fish Hatchery (CNFH) in Battle Creek in 2014. Eggs from fall-run Chinook salmon that stray to Nimbus Hatchery will be returned to CNFH to ensure a healthy population of these fish for commercial, recreational and ecological purposes.

“These fish were born at the height of the drought in 2014,” said Jay Rowan, California Department of Fish and Wildlife (CDFW) North Central Region Senior Environmental Scientist. “They were trucked to the Delta as fry and released near Rio Vista and the San Pablo Bay as part of a massive effort to improve their chances for survival in a year of poor river conditions.”

Returning now as adults, many of these salmon will stray into the American River and not return to their home waters to spawn. The lack of returning fish will make it extremely difficult for the CNFH to reach their goal of producing 12 million fall-run Chinook salmon this fall to release in the waters below Lake Shasta.

CDFW is partnering with the U.S. Fish and Wildlife Service (USFWS), with the support of the Bureau of Reclamation, to collect eggs at Nimbus Fish Hatchery to assist CNFH in meeting its production goals and maintaining a stable salmon population on Battle Creek and the upper Sacramento River.

When the salmon reach Nimbus Hatchery, staff will separate out the fish that have had their adipose fin removed, indicating that they carry a tiny coded wire tag that records their hatchery of origin. Fish identified as being of CNFH origin will be spawned with one another, and their fertilized eggs returned to CNFH. Fish that have not had their adipose fin removed will be spawned and their eggs held until it is determined if they will be needed to meet CNFH production goals.  Fish that are not yet ready to spawn will have a colored tag attached to their dorsal fin and will be returned to the American River, where they will be available to anglers until they either spawn naturally or climb the ladder again and are spawned at the hatchery to meet the Nimbus Fish Hatchery egg collection goals. While anglers are able to catch and keep fish marked with these tags, the tags have no monetary value and do not need to be returned to CDFW.

Lower American River contains unsafe levels of E. coli. Are homeless camps to blame?

Levels of E. coli bacteria found in the lower American River exceed the federal threshold for safe recreational use, in part due to human waste from homeless camps, state regulators say.

The Central Valley Regional Water Quality Control Board has proposed adding the bacteria to a list of pollutants that make the lower American River a federally designated impaired water body. A state board is expected to sign off on the decision later this year and ask for final approval from the U.S. Environmental Protection Agency.

E. coli can sicken and even kill people who swim in or drink contaminated water. State regulators say they’re not aware of anyone who has been sickened by E. coli in the the lower American River, but nearly a decade of test data indicate the risk of exposure.

“It should give people some discomfort about using the water – it’s not good,” said Ron Stork of Friends of the River.

A report summarizing test results from 2007 to 2014 found average levels of E. coli at three sites that were higher than the EPA standard, “beyond which the water body is not recommended for recreation.” The three sites are in the westernmost section of the American River Parkway, near downtown Sacramento, where the highest concentration of homeless camps are set up.

Seventeen of the 25 test sites had at least one recording in excess of the federal threshold, according to the “Safe-to-Swim Assessment.”

Thousands of people use the lower American River each year, from the boaters who launch at Discovery Park, to the swimmers who enjoy the beach at Sutter’s Landing Regional Park, to the triathletes who participate in Eppie’s Great Race.

“My concern is that it could make me sick,” said Alex McDonald, who was sitting in the water with his wife at Sutter’s Landing last week. “I would like to know more.”

Supervisors OK effort to clean up American River Parkway’s homeless camps

Sacramento County supervisors on Wednesday approved a $5 million plan to beef up patrols along the American River Parkway and clean up its homeless encampments.

The 3-2 vote came after dozens of residents packed the supervisors’ chambers to support or denounce the proposal to add park rangers, maintenance staff and sheriff’s employees to the 23-mile “jewel of Sacramento” and adjacent neighborhoods.

Some speakers recounted bad interactions with homeless people. Others expressed compassion for the homeless but said they wanted a clean, safe parkway. Still others denounced the proposal as “criminalizing the homeless.”

Supervisors Phil Serna, Don Nottoli and Patrick Kennedy voted for the measure. Supervisors Susan Peters and Sue Frost voted against it, citing concerns about funding.

Kennedy said the issue is “a tale of two tragedies” – homelessness and the condition of the parkway. “I think (the plan) is a little heavy on the law enforcement side, and I fear it will just move people around,” Kennedy said. “But we have to try something … It’s devastating. We just can’t let (the parkway) continue to deteriorate.”

Aimee Rutledge, head of the Sacramento Valley Conservancy, said the conservancy’s property, Camp Pollock, is at “ground zero” in the lower reaches of the river with a clear view of the degradation of a precious natural resource. “To abandon (the parkway) would be to abandon the best part of Sacramento,” she said.

Last month, supervisors asked staff to find ways to fund additional employees for animal control, waste collection and the Sacramento County Sheriff’s Department Homeless Outreach Team.

Staff members found several sources of funding but not enough to cover the full costs of the program. Staff laid out options costing $3 million, $4 million and $5 million, which had $1.4 million, $2.9 million and $3.8 million funding gaps. Going forward, the funding gaps increase to $1.8 million, $3.2 million and $3.9 million for consecutive budget years, they said.

“Where is the money going to come from?” Peters asked Wednesday.

County Executive Nav Gill said there’s a $3.4 million placeholder in the budget that will come before the board next month and could be used to fund the parkway plan.

Serna launched the parkway debate in June when he requested between $3 million and $5 million to address the impacts of homeless campers.

Other supervisors countered that campers would simply move into the surrounding neighborhoods when rousted. As a compromise, the board asked staff to come up with options to also clean up unincorporated areas of the county adjacent to the parkway.

Karen Humphrey, former mayor of Fresno, told supervisors the plan will “just move the problem around and waste precious resources.” She said she helped create the San Joaquin River Parkway, modeled on Sacramento’s parkway, so she understands its importance. But there isn’t enough capacity to shelter all of the people living in the brush, she said.

Earlier this year, supervisors voted to dedicate $6.2 million to a slew of new homeless initiatives on top of the county’s roughly $40 million in annual spending for homeless services.

The county will build a 75-bed shelter aimed at moving chronically homeless people off the streets. It’s scheduled to open in early 2018, and the county estimates it could serve 300 people annually. The money will also pay for a rehousing program, transitional housing and case workers.

Push for more patrols on American River Parkway

The American River Parkway is Sacramento County’s urban jewel, but in recent years, it’s become tarnished with litter, debris and close encounters with aggressive dogs protecting homeless campers.

“I’ve had pit bulls coming after me,” said Mike Golden, a bicyclist on the American River Parkway. “I’ve had two pitbulls coming out after me, one each side.”

Golden loves biking along the parkway, but told KCRA 3 he’s increasingly concerned about public safety.

“You’ve got a small minority of the population, the homeless — they are really destroying it for the vast majority of the users of the Parkway,” Golden said.

There are hundreds of people living illegally along the American River Parkway.

For Sacramento County Supervisor Phil Serna, the issue is personal after he suffered a health scare during a cleanup of the American River Parkway.

“I was accidentally stuck by a hypodermic needle,” Serna said.

“We continue to see not just hypodermic needles but propane tanks and large trash piles and off-leash dogs that are aggressive,” he said.

The needle incident occurred several years ago, but Serna now wants to allocate $5 million to add up to 10 additional park rangers, increasing the number from roughly 25 to 35.

“There would be several more teams of park rangers working collaboratively with park maintenance staff, community prosecutors, social workers to make sure we’re keeping the parkway clean, safe and make sure the people that need help the most here are going to receive that help.”

The money would be used to help remove people who are camping illegally and causing environmental harm.

Jeremy Donnelson and Mary Weick live in a homeless encampment just 100 yards from the bike trail in Discovery Park. They said they’ve been living behind tarps for four months and have never seen a park ranger.

They’re not happy about the prospect of someone telling them to move.

“I would feel that would be taking away from the homeless, like the government’s been trying to do for a long time and trying to make being homeless illegal,” Weick said.

“Being homeless yeah it’s illegal whatever, but there’s more people becoming homeless because less jobs,” Donnelson added. “But they have to realize that we need a place to go too.”

While some in the homeless community might want permanent low-cost housing, it’s not for everyone.

“I can only handle indoors for so long,” Donnelson said. “I don’t know what it is about indoors. I’m indoors for a while and I start getting antsy. I can’t stand being indoors for too long.”

But for many people who enjoy activities on the parkway, it’s really a matter of safety.

Placer County Sheriff’s Deputies discover huge transient camp in Auburn

Last week, the Placer County Sheriff’s Homeless Liason Deputies Team discovered a large transient encampment near the Foresthill Bridge in Auburn.

The camp was on private property, and all those found camping there were given warnings to vacate the camp, according to a post on the Placer County Sheriff’s Office’s Facebook page.

In addition to many homeless campers, deputies also found fire pits and a large amount of trash, according to the Facebook page. The Sheriff’s Office posted a video of the camp, which shows a wide array of tents, signs, food and even some electronics at the camp.
