<br />4. Erosion Control Dam. An Erosion Control Dam (ECD) is <br />a dam which may be constructed on normally dry water <br />courses for the purpose of erosion control. The dam <br />cannot have a vertical height exceeding 15 feet measured <br />from the upstream toe to the bottom of the spillway <br />channel, nor have a capacity exceeding ten acre-feet at <br />the spillway level. An ECD must have an ungated outlet <br />conduit with a 12-inch minimum diameter, or large <br />enough to pass any storage in excess of two acre-feet in <br />36 hours. The dam may be constructed to impound two <br />acre-feet of water below the outlet intake, There are <br />standard specifications for construction that are provided <br />with the application form which is available from the <br />State Engineer's Office. <br /> <br />5.
