老肯尼特采矿镇,大约1944年被上涨的沙斯塔湖水淹没

沙斯塔坝 (Shasta Dam,施工前称为「肯尼特坝」,Kennett Dam)是一个横跨美国加利福尼亚州北部萨克拉门托河的重力坝,位于萨克拉门托河谷​​的北端。此坝主要用于长期储水与其水库-沙斯塔湖-的洪水控制,同时也用作水力发电。高达602英尺(183米),它成为了美国第九高的水坝,并形成了加州最大的水库。

因为洪水和干旱频繁地困扰加州最大的农业地区——中央河谷,早在1919年水坝便被构想出来,1930年代,此坝首次被批准为一项州工程。可是,这恰好碰上大萧条,水坝的建造被移交给联邦垦务局,作为一项公共事业计划。1937年,在首席工程师Frank Crowe的监督下,开始认真建造。建造期间,水坝创造了数千急需的就业岗位;1945年,它在计划前26个月完工。完工后,此坝成了继胡佛水坝之后第二高的水坝,并被认为是有史以来最大的工程壮举之一。

Shasta Dam (called Kennett Dam before its construction) is a concrete arch-gravity dam across the Sacramento River in Northern California in the United States. At 602 feet (183 m) high, it is the eighth-tallest dam in the United States. Located at the north end of the Sacramento Valley, Shasta Dam creates Shasta Lake – the largest reservoir in California – for long-term water storage, flood control, hydroelectricity and protection against the intrusion of saline water. The largest reservoir in the state, Shasta Lake can hold about 4,500,000 acre feet (5.6×10 m).
