Who needs to file an application for a dam permit?
Any person who intends to construct, reconstruct or alter a dam that has a crest height 20 feet or higher, as measured from the downstream toe to the crest, or has a crest height less than 20 feet but will impound 20 acre-feet or more of movable material, must acquire a dam safety permit prior to construction. This provision does not pertain to United States Bureau of Reclamation or United States Army Corps of Engineer projects.
