Suit filed against FWS over San Francisco Smelt

The Center for Biological Diversity announced last Friday that it had filed suit in federal court against the Fish & Wildlife Service (FWS) seeking increased protections for two small smelt native to the Bay Area in Northern California. The group's press release can be read here.

The two species of smelt, the delta smelt and the longfin smelt, are at the bottom of a long battle over supplying water for irrigation to farmers in the region, and drinking water to area residents. As in other areas out West, much of this water is supplied through heroic diversions from once free-flowing rivers and streams that have threatened the viability of native fish species. And last week, Governor Schwarzenegger signed an $11bn water bond bill that would fund more engineering feats to get water to thirsty farmers and residents--at the expense of the longfin and delta smelt, according to CBD.

CBD and other environmentalists have been battling to force state and federal officials to take the smelt into consideration in their water use decisions using the Endangered Species Act for some time now. FWS issued a Biological Opinion last December asking that diversions be stopped to protect the delta smelt, already listed as threatened under the Act. But local water districts petitioned to have the protective actions called for by the BiOp enjoined, and the Eastern District of California granted that injunction last May.

Now that the bond bill has been passed, CBD is upping the ante. It wants the longfin smelt in the Bay-Delta area to be granted protection under the ESA as a distinct population segment (DPS)--something that FWS declined to do in this decision from April. It also wants FWS to change the delta smelt's status from threatened to endangered, which would trigger additional protections under the ESA, and possibly change the scope of action California is able to take.
