<br />improved to provide control of a standard project flood result- <br />ing frOlll runoff downstream frOlll the dam. The channel would be <br />designed to convey the greater of either the maximum release <br />necessary for evacuation of the Cherry Creek and Castlewood <br />Reservoirs or the standard project flood. Existing drop <br />structures would be removed. The channel would be enlarged <br />and straightened where necessary. Five drop structures would <br />be installed at appropriate locations. Between the Cherry Creek <br />Dam and the existing lined channel, the channel slopes would be <br />protected with riprap. The existing lined channel would be <br />repaired as required over the project life. The channel bed <br />between the concrete walls would be armored with riprap to <br />protect the toe of the retaining walls. The improved channel <br />would consist of five reaches. Pertinent data for the Cherry <br />Creek channel improvements are shown in table 3. <br /> <br />37 <br />
