<br />SWDED-H (S'.oI~EH 3 Oct 67) 1st lod <br />SUBJEC'r: Las Animas Local Protection Project, Las Animas, Colorado, <br />and Vicinity, Design Memorandum No.1, Hydrology <br /> <br />h. Pa.r 9-13, page 31. The hydraulic design of the several <br />gravity drainage structures is dependent on ponding a portion of the <br />vol\lllle of the design flood. It is requested that the district submit, as <br />a revision to this design memorandum or in the general design memorandum, <br />the design flood inflow-outflow hycU-ographs and mass curves along with the <br />capacity Cl.\rVes of the ponding areas and data pertaining to the limiting <br />factors which restrict storage in each area in order to show whether the <br />hydra.ulic design of the gravity drainage structure should provide for the <br />peak rate of flow as given in table 15 or for a reduced rate of flow. <br /> <br />1. Plate 19.
