Groups May Sue PG&E Over Spring Chinook

A coalition of environmental groups are prepared to sue Pacific Gas and Electric (PG&E) over its operations at DeSabla-Centerville dam on Butte Creek, which they say have contributed significantly to major declines in the abundance of Spring Chinook over the last decade. Butte Creek is one of the last remaining strongholds for endangered spring chinook in the Sacramento system. Spring chinook enter freshwater early and over-summer in their natal stream before spawning in early fall. In California's hot, dry climate they rely on over summer snow melt to keep water temperatures at a suitable level for their survival. Unfortunately, over the last several summers, operators at the dam have failed to release sufficient water into the lower river leading to low flows, elevated temperatures and high prespawn mortality in the endangered chinook. Furthermore, fish passage is blocked at Centerville dam meaning fish can no longer access the upper portion of Butte Creek and PG&E's re-licensing application approved in 2007 provided no money for mitigation of the dams harmful effects.
