Another upcountry lake is under emergency status in order to repair failing infrastructure, according to a spokesman for the El Dorado District’s hydroelectric division. Silver Lake, along with Caples Lake which straddles the border between Amador and El Dorado Counties, is undergoing immediate repairs after underwater inspections revealed serious deterioration of devices that control water storage and releases. The two lakes are both part of an intricate system of lakes and canals that provide a large portion of the hydroelectric generated power in the local area.
An inspection at Silver Lake found that steel bracing and gate stems on an outlet tower were extremely corroded. Last month’s inspection of Caples Lake revealed excessive leakage through underwater slide gates. Despite the damage and an emergency declaration by the El Dorado Irrigation District, there is no threat of dam failure, said one district representative. Under state law, the emergency declaration allows the district to contract for equipment and services without competitive bids. The 8,700-acre-foot Silver Lake represents some 38 percent of the district’s water storage capacity. Officials advise residents to take precautions when swimming or fishing in surrounding rivers and streams, as water levels could rise and fall erratically while repairs are taking place. Officials expect the repair to meet normal expectations for a quick project.
