Surveying the Sacramento River and Delta March 7, 2017 How CDFW uses a combination of scientific techniques to better understand fish populations and the general health of Northern California waterways. (video) Since 1959 the California Department of Fish and Wildlife (CDFW) has used a combination of scientific techniques to better understand fish populations and the general health of Northern California waterways. Examples include tagging sturgeon, trawling the Delta for smelt, and counting salmon carcasses. CDFW uses data from these strategies and others to help influence operations of the State Water Project and Central Valley Project, ultimately helping decision makers determine water flows. This short video highlights these operations along the Sacramento River and into the Delta, including a smelt survey conducted by Environmental Scientist Felipe la Luz.

Fisheries Biologists Showcase Delta Bass at International Sportsmen’s Expo Among the more popular attractions at the Sacramento International Sportsmen’s Expo each January is the Western Bass Aquarium Demo Tank.The 6,000-gallon aquarium displays dozens of trophy largemouth bass collected by CDFW biologists from the Sacramento-San Joaquin Delta. Pulse Flows Expected to Boost Brown Trout Fishery in Owens River Gorge From boom to bust to decades of angler indifference, few California fisheries have experienced such wild swings of fortune as Mono County’s Owens River Gorge. CDFW Biologists Confirm Green Sturgeon Spawn in Yuba River CDFW biologists have been taking a new approach to looking at reproduction in one of the oldest fish species in existence. Green sturgeon, which are listed as threatened under the Federal Endangered Species Act, are in effect a living fossil, having swam in both the fresh and ocean waters from California to Alaska for more than 200 million years. Going with the Flow: CDFW’s Water Branch Keeps a Careful Eye on California’s Riverine Resources Taking care of California’s fish and wildlife wouldn’t be possible without managing the resources upon which they depend. To that end, CDFW has an entire branch – and many scientific staff – dedicated to the scientific study, and planning and management of water resources. Sweetwater River Habitat Restoration California’s drought emergency was officially declared to be over last year, but its deleterious impact on fish habitat is still being felt in many parts of the state -- especially in arid parts of Southern California. In order to help offset these effects at one site in northern San Diego County, CDFW biologists and other staff recently toiled to create spawning beds for rainbow trout. Comments are closed.
