The objective is to develop suitable means for the screening and diversion of 

 large numbers of small striped bass, chinook salmon, catfish, shad, and other 

 fish in the San Joaquin-Sacramento River Delta which are affected by a large 

 diversion of water (4, 600 second-feet) through a pumping plant and into the Delta- 

 Mendota Irrigation Canal. Various types of fish screens and fish collection de- 

 vices are being studied.
