The interior drain ditch would be located adjacent and par- <br />al lei to the levee, beginning about one mi Ie northwest of the city and <br />terminating at an outlet structure about 3 mi les downstream. Intake <br />structures would be provided where the levee crosses the Las Animas <br />Consol idated Canal and the Las Animas Town Ditch. Outlet structures <br />would be instal led through the levee for the disposal of interior <br />runoff and to serve as wasteways for the Irrigation canals. Culverts <br />would be provided where the Interior drainage ditch passes under U,S. <br />Highway 50 and the Arkansas Va I I ey Branch I I ne of the AT&SF Ra i Iway <br />System. Two ponding areas total ing about 80 acres would be reserved <br />for storing Interior runoff during periods of high river stages. <br /> <br />30 <br /> <br />R 1/28/64 <br />
