Document Description
The California of Fish and Wildlife is issuing Amendment No. 2 for the Streambed Alteration No. 1600-2013-0013-R4 issued to the California Department of Fish and Wildlife, San Joaquin River Restoration Program. The Project includes the annual temporary installation of a combination of up to eight (8) rotary screw traps (RSTs) and fyke nets within the San Joaquin River to determine the feasibility of use of both methods to (1) assess juvenile fall0run Chinook salmon (Onchorhynchus tshawytscha) migration behavior; (2) assess in-river spawning success and survival through mark recapture of river reared fall-run juveniles in comparison to unmarked naturally spawned juveniles; and (3) assessment of trap capture efficiency utilizing marked and released juvenile fall-run salmon of various developmental stages. Amendment No. 2 adds additional trapping locations and extends the seasonal period of trapping. The extension extends the expiration date of the agreement to March 1, 2023.
