|In addition to destroying and threatening thousands of homes and businesses, the devastating Glass Fire in Napa and Sonoma counties jeopardized the California Department of Fish and Wildlife’s (CDFW) Inland Chinook Salmon Program – until the Feather River Fish Hatchery in Oroville came to the rescue. The Feather River Fish Hatchery is owned and maintained by the California Department of Water Resources – and operated by CDFW.|
Each year, CDFW raises approximately 800,000 Chinook salmon smolts and fingerlings for planting and recreational fishing in large foothill and valley reservoirs from Fresno County to Trinity County. These landlocked salmon often grow quite large and fill an ecological and recreational angling niche in these deep-water impoundments not typically occupied by other fish species.
The state record inland Chinook salmon came from Trinity Lake in 2013 weighing 20 pounds, 15 ounces. Anglers regularly catch inland Chinook salmon weighing 7 to 8 pounds at Lake Oroville and 5 to 6 pounds at Folsom Lake.
The inland Chinook salmon originate with eggs collected and spawned at the Feather River Fish Hatchery each fall from salmon returning to the Feather River. The eggs and fish are excess to the hatchery’s annual production goals. About 1.4 million Chinook salmon eggs were collected from the Feather River Fish Hatchery in early October and designated for the Inland Chinook Salmon Program.
Ordinarily, most of these eggs are taken to CDFW’s Silverado Fisheries Base in Napa County for incubation, where they remain until the baby salmon are big enough for stocking. The Silverado Fisheries Base suffered power outages and came under threat of evacuation as a result of the Glass Fire.
In response to the emergency and with assistance from CDFW’s Inland Chinook Salmon Program staff, temporary adjustments were made at the Feather River Fish Hatchery to keep the eggs, incubate them and grow out the salmon until the Silverado Fisheries Base is once again able to accommodate the fish, likely in November.
CDFW staff set up additional fish-rearing incubators in their Inland Chinook Salmon Building. That building typically only has space to hold 300,000 eggs and baby salmon destined for Lake Oroville. Thanks to the extra effort, the Feather River Hatchery is now holding 1.4 million eggs that represent the entire annual production of the state’s Inland Chinook Salmon Program.
“Understanding the inherent risk of losing an entire year’s production, CDFW staff will play a crucial role in ensuring future inland Chinook fisheries in Folsom, Oroville and eight other lakes and reservoirs,” said Kyle Murphy, a senior environmental scientist with CDFW’s Fisheries Branch. “This interagency teamwork will have long-reaching effects for thousands of anglers in central and northern California.”
Adding to the stress, the Feather River Fish Hatchery itself was ordered to evacuate for a day Oct. 15 due to a nearby fire in Oroville. Both the Oroville fire and the Glass Fire have been contained and no longer pose threats to either facility.

At its Nov. 16 quarterly meeting, the Wildlife Conservation Board (WCB) approved approximately $28 million in grants to help restore and protect fish and wildlife habitat throughout California, including the Salton Sea. Some of the 17 funded projects will benefit fish and wildlife – including some endangered species – while others will provide the public with access to important natural resources. Several projects will also demonstrate the importance of protecting working landscapes that integrate economic, social and environmental stewardship practices beneficial to the environment, landowners and the local community. The state funds for all these projects come from bond measures approved by voters to help preserve and protect California’s natural resources. Funded projects include:
- A $14 million grant to the California Department of Water Resources for a cooperative project to construct approximately 640 acres of wetland habitat, including deep water channels, shallow ponds, island refugia and nesting structures. The project will enhance habitat for fish-eating birds on the edge of the Salton Sea at the terminus of the New River, seven miles northwest of the City of Westmorland in Imperial County.
- $2.2 million to acquire approximately 624 acre-feet of water and storage rights in Heenan Lake for protection of the Lahontan cutthroat trout fishery located near Markleeville in Alpine County.
- A $3.7 million grant to the Land Trust of Napa County for a cooperative project with the State Coastal Conservancy, California Natural Resources Agency and others to acquire a conservation easement over approximately 7,266 acres of land. This will preserve and protect managed forest lands, riparian corridors and watersheds that support rare and special status wildlife species and vegetation near the City of Calistoga in Napa County.
- A $415,000 grant to the Land Trust of Santa Cruz County for a cooperative project with the State Coastal Conservancy and California Natural Resources Agency to acquire a conservation easement over approximately 133 acres of land. This will protect important watersheds, including stream and source waters, and maintain native terrestrial communities and landscape connectivity near Scotts Valley.
- A $3.4 million grant to the Mountains Recreation and Conservation Authority for a cooperative project with the Santa Monica Mountains Conservancy and the County of Los Angeles, to acquire approximately 71 acres of land. This will protect chaparral, coastal sage scrub, native grasslands and oak woodland-savannah habitat, enhance wildlife linkages, protect watersheds and provide future wildlife-oriented public use opportunities near the City of Agoura in Ventura County.

California agencies combatting the spread of invasive quagga and zebra mussels remind boaters to remain cautious over Memorial Day weekend.
Quagga and zebra mussels are invasive freshwater mussels native to Eurasia. They multiply quickly, encrust watercraft and infrastructure, alter water quality and the aquatic food web, and ultimately impact native and sport fish communities. These mussels spread from one body of water to another by attaching to watercraft, equipment and nearly anything that has been in an infested waterbody.
Microscopic juveniles, invisible to the naked eye, are spread from infested waterbodies in water entrapped in boat engines, bilges, live-wells and buckets. Quagga mussels have infested 29 reservoirs in Southern California and zebra mussels have infested San Justo Reservoir in San Benito County.
To prevent the spread of these mussels and other aquatic invasive species, people launching vessels at any body of water are subject to watercraft inspections and are strongly encouraged to clean, drain and dry their motorized and non-motorized boats, including personal watercraft, and any equipment that comes into contact with the water before and after recreating.
“Recreational water users play a crucial role in preventing new mussel infestations,” said California Department of Fish and Wildlife (CDFW) Director Charlton H. Bonham. “Their awareness, diligence and good stewardship helps to maintain both the ecological and recreational values of our waters.”
To ensure watercraft are clean, drained and dry, many local agencies conduct boat inspections. The CDFW website provides a list of these inspection programs (www.wildlife.ca.gov/mussels), along with additional information about the invasive mussels and what people can do to help prevent their spread in California. Prior to traveling, boaters should contact destination waterbodies directly to check for restrictions and requirements.
Take the following steps both before traveling to and before leaving a waterbody to prevent spreading invasive mussels, improve your inspection experience and safeguard California waterways:
- CLEAN — inspect exposed surfaces and remove all plants and organisms,
- DRAIN — all water, including water contained in lower outboard units, live-wells and bait buckets, and
- DRY — allow the watercraft to thoroughly dry between launches. Watercraft should be kept dry for at least five days in warm weather and up to 30 days in cool weather.
CDFW has developed a brief video demonstrating the ease of implementing the clean, drain and dry prevention method, which can be viewed at www.youtube.com/watch?v=GaeAIPLoK-k. In addition, a detailed guide to cleaning vessels of invasive mussels is available on the California State Parks Division of Boating and Waterways (DBW) at http://dbw.parks.ca.gov/PDF/CleanGreen/Boating-QuaggaGuide.pdf.
Travelers are also advised to be prepared for inspections at California Department of Food and Agriculture (CDFA) Border Protection Stations. Over the past nine years, more than one million watercraft entering California have been inspected at the Border Protection Stations. Inspections, which can also be conducted by CDFW and California State Parks, include a check of boats and personal watercraft, as well as trailers and all onboard items. Contaminated vessels and equipment are subject to decontamination, rejection, quarantine or impoundment.
Quagga and zebra mussels can attach to and damage virtually any submerged surface. They can:
- Ruin a boat engine by blocking the cooling system and causing it to overheat
- Jam a boat’s steering equipment, putting occupants and others at risk
- Require frequent scraping and repainting of boat hulls
- Colonize all underwater substrates such as boat ramps, docks, lines and other underwater surfaces, causing them to require constant cleaning
- Impose large expenses to owners
A multi-agency effort that includes CDFW, DBW, CDFA and the California Department of Water Resources has been leading an outreach campaign to alert the public to the quagga and zebra mussel threats. A toll-free hotline, 1 (866) 440-9530, is available for those seeking information on quagga or zebra mussels.
