On January 15th the U.S. Bureau of Reclamation (Bureau) and the Department of  Water Resources (DWR) released a working draft of the biological assessment (BA) for the California WaterFix, also known as the Twin Tunnels. 

The BA, required by Section 7 of the federal Endangered Species Act, will provide the basis for consultation with the U.S. Fish and Wildlife Service and the National Marine Fisheries Service to determine whether the proposed action is likely to adversely affect listed species or designated critical habitat, jeopardize the continued existence of species that are proposed for listing, or adversely modify designated critical habitat.   

The BA can be accessed here.
