Document Description
The Bellota Weir Modification Project (Project or proposed Project), a continuation of the Calaveras River Anadromous Fish Protection Project and requirement of the Calaveras River Habitat Conservation Plan (CHCP), is a proposal by the Stockton East Water District (SEWD) to design, permit and install a modern fish screen and related improvements at SEWD’s Bellota Intake Structure. Project components include construction of a new screened diversion intake and associated conveyance improvements, construction of “fishways” comprised of a roughened channel and fish ladder to improve upstream anadromous fish migration from Mormon Slough, and construction of a fish exclusion structure on the Old Calaveras River to prevent entrainment of juvenile salmonids. The Project has been developed collaboratively with other interested agencies, including, California Department of Fish and Wildlife (CDFW), National Marine Fisheries Service (NMFS) and U.S. Fish and Wildlife Service (USFWS) to define a final course of action to eliminate known fish passage impediments while improving Bellota Intake Structure operational flexibility. The Project plans continue to be refined in consultation with resource agencies.
