San Joaquin River restoration to begin

FRESNO, Calif. — Federal officials are preparing to release the first surge of water from a Fresno-area dam to reawaken miles of the San Joaquin River and restore salmon runs that went dry in the 1940s.

The Bureau of Reclamation is set to begin the historic restoration of the state’s second-largest river at 6 p.m. (9 p.m. EDT) Thursday when officials release pulses of water along the dry riverbed.

The project to bring back salmon to the river is a milestone in a decades-long legal tussle between environmentalists, farmers and the federal government.

Environmental groups had filed a lawsuit stemming from the opening of Friant Dam in 1949, which dried up portions of the river below the dam where salmon once ran thick. Congress approved a legal settlement in March that aims to bring back Chinook salmon by 2012.
