<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. F.YPmDt Sttuctures. Exempt structures or dams are listed <br />in Table 1. The word "exempt" is used in the statutes to <br />exclude structures from the control of the State Engineer's <br />Office. Exempt dams are monitored by agencies other <br />than the State Engineer's Office. Telephone numbers of <br />agency contacts for various exempt structures are listed <br />in Table 1. The State Engineer's Office may be involved <br />in evaluating an exempt structure, if requested by the <br />responsible agency, or to confirm exempt status. <br /> <br />3 <br /> <br />~ <br />
