<br />SOIL CONSERVATION SERVICE ACTIVITIES(CONTID.) <br /> <br />and in preserving the watershed itself, appears to depend on the extent <br /> <br /> <br />to whioh the same or similar treatment is applied in the future to the <br /> <br /> <br />bll.Si1i. as a whole; and on the effioienoy with whioh suoh faoilities are <br /> <br /> <br />maintained after their initial oonstruotion. <br />Soil erosion and runoff retardation devioes, of themBelves, <br />beoome measures of flood oontrol, partioularly in favorable areas and <br />where storms are of low to moderate intensity. Suoh devioes, alone, oan- <br /> <br /> <br />not be expeoted to prevent floods resulting from oloudburst storms over <br /> <br /> <br />watersheds of steep slopes. Supplemental faoilities are essential, and, <br /> <br /> <br />in the Cherry Creek basin, these might properly take the form of retarding <br /> <br /> <br />barriers, one or more on eaoh tributary, of sizes appropriate to the re- <br /> <br /> <br />quirements. Barrier sizes will be large in oomparison with the so-oalled <br /> <br /> <br />"oheok-dams" or "retarding basins" oonnnonly installed by the Soil Conserva- <br /> <br /> <br />tion Servioe, but will be relatively small as oompared to the dams, res- <br /> <br /> <br />ervoirs and barriers frequently designed and oonstruoted by the Reolamation <br /> <br /> <br />Bureau and the U. S. Engineer Corps. <br /> <br />HISTORY OF ORIGINAL CASTLEHoon DAM. <br /> <br />Castlewood dam, whioh failed Aug. 3, 1933, was originally <br /> <br /> <br />oonstruoted in 1890 (at a oost of 0260,000) by the Denver TIater Storage <br /> <br /> <br />Co. Castlewood Reservoir has a storage deoree for 5,257 aore feet of <br /> <br /> <br />water, with a priority date Sept. I, 1889. <br /> <br /> <br />Hater released from the reservoir was oonveyed, via the <br /> <br /> <br />Arapahoe Canal (30-miles long), to the Clark Colony, south of Denver, <br /> <br /> <br />where it was used for the irrigation of 10-aore suburban traots. The <br /> <br /> <br />system experienoed diffioulties, and has been involved in several reoeiver- <br /> <br />-8- <br />
