Surveying the Sacramento River and Delta

Surveying the Sacramento River and Delta

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. link opens in new windowThis short video highlights these operations along the Sacramento River and into the Delta, including a smelt survey conducted by Environmental Scientist Felipe la Luz.
