Before joining the administration, Bernhardt worked as a lobbyist and lawyer for the Westlands Water District, the nation’s largest agricultural water contractor. “What the new biological opinions do is provide a degree of operational flexibility,” he says, allowing the pumps to take more water when more is available. The delta smelt (Hypomesus transpacificus) is a small and relatively obscure fish that has recently risen to become a major focus of environmental concern in California.It was formally abundant in the low-salinity and freshwater habitats of the northeastern San Francisco Estuary, but is now listed as threatened under the Federal and California State Endangered Species Acts. 1 San Luis & Delta-Mendota Water Authority v.

It could take years for the full effects of the new policy and litigation to become apparent. They say enlarging the Twitchell Island Channel in the Sacramento Delta could eliminate reverse water flows sucking young smelt into the pumps of the State Water Project. “Revolutions are expensive, I guess, and no one wants to be the one to pay for them.”. “As biologists, we call those ecosystem inputs,” he says with a laugh. The Delta Smelt is a small fish in the middle of a big controversy in the Sacramento-San Joaquin River Valley. The tiny fish has a lifespan of one year and is a primary food source to striped bass and large-mouth bass, which are invasive species in Sacramento Delta.
