BCID Fish Screen

BCID, the U.S. Bureau of Reclamation, and other Federal, State, and municipal agencies collaborated to build a fish screen facility at BCID’s diversion point on the San Joaquin River.

A fish-friendly pumping system highlights the fish screen facility that provides protection to threatened and endangered fish species.  The facility went into operation on April 2, 2002.

BCID has diverted water from the San Joaquin River since the early 1900s, but the diversion had been unscreened during most of its operational life.

BCID Partners in Fish Population Project

This short video produced by FISHBIO highlights a mark-recapture study to evaluate non-native fish populations in the San Joaquin River. BCID is a partnering agency on the project.

This study uses large fyke traps to sample fish. One unique aspect of this study is that fishermen can help in the data collection process by returning tags of fishes that were marked. This information can help us estimate how big their populations are.
