Our media partner the San Jose Mercury News reports the environmental groups, including the Sierra Club, filed a motion with the federal government in 2005, urging federal officials to require that the dam's emergency spillway be armored with concrete, rather than remain as an earthen hillside.

The Federal Energy Regulatory Commission rejected the request after the state department of water resources and other water agencies said the upgrades were unnecessary.
