Dams

Dam safety statutes are enumerated in Idaho Code §§42-1709 through 42-1721. The definition of height to be used for determining compliance with Idaho Code is measured vertically from the natural bed of the stream or watercourse at the downstream toe of the barrier to the maximum water storage elevation. Hydraulic structures greater than or equal to ten (10) feet height and reservoirs that impound a volume of water greater than or equal to fifty (50) acre-feet are regulated by the IDWR Dam Safety Program for benefit of public safety, unless specifically exempted per Idaho Code. Note that regardless of size, any water storage embankment may be regulated for public safety if IDWR determines that the potential failure consequences would result in significant damage to downstream life or property.

大坝安全相关法规已在《爱达荷州法典（Idaho Code）》第42-1709条至第42-1721条中予以明确列举。用于判定是否符合《爱达荷州法典》要求的高度定义，为从坝体下游坝趾处的河道天然河床至最大蓄水水位的垂直测量距离。高度不低于10英尺的水工构筑物，以及蓄水量不低于50英亩-英尺的水库，均由爱达荷州水资源部（Idaho Department of Water Resources，简称IDWR）大坝安全项目纳入监管以保障公共安全，除非依据《爱达荷州法典》另有明确豁免条款。需注意的是，无论规模大小，若IDWR认定某蓄水堤坝的溃坝潜在后果将对下游生命或财产造成重大损害，则该堤坝仍需纳入公共安全监管范畴。
