1937 (Sediment control bv potenti~l pro1ect) . INITIAL DEVELOPMENT Pueblo Reservoir ------ -- - - . The Pueblo Reservoir, which would be conet~cted in the Initial Developoent to 400,000 ~cre-feet cRpacity would control all of ths sedinent passing the st~tion on the Arkansas River at Pueble, or 656 acre-feet yearly. As the benefits accruing to the Initial Developnent are based on a 100-year period, the capacity in the Pueblo Reservoir allotted to sediment was also computed on the basis of that period. The sediment capacity of 65.600 acre-feet for the potential Pueblo Reservoir was determined by multiplying 656 acre~feet, the annual amount which would be retained in the reservoir, by 100 yearB. A new capacity curve waB computed (table 8) for the reservoir to show the capacity remaining at the end of the 10o-year period. This curve is shown on exhibit 4.
