Changes proposed to Calif. twin tunnel project

The height of pumping plants would also be reduced and the tunnels’ length would  be shortened from 35 miles to 30 miles. The tunnels would carry water  south from the delta to vast farmlands and thirsty cities. Proponents say the  project would provide a reliable water supply while reducing the mortality of  threatened fish, because water would mostly be diverted from the north portion  of the delta, where fish would not be sucked into deadly pumps. more@sacbee
