, '. city. Its present capacity is about I Id,ooo c.f.s. Barrier'Dam is a concrete gravity and earthfi I I retarding structure across the Arkansas River about 6 mi les above Pueblo~ The dam, with a reservoir storage capacity of 20,500 acr'e~feet at spi Ilway crest, was designed to regulate major floods to the capacity of the floodway through Pueblo. The struc- ture also has a regulating effect on downstream flows. It is estimated that if the dam had bee n In p I ace pr I or ,to the 1921 flood, the flood peak at l.as Animas would have been redu~ed from 187,000 c.f.s. to 140,000 c. f.s. 32. Loca I flood protect I on works of sma II er scope have been con- structed by local interests on Fountain' Creek at Colorado Springs and Wild Horse Creek at Holly. These improvements consist of diversions, floodways, channel improvement, and levees. 33. AUTHORIZED WATER RESOURCES DSVELOPMENT.- The Flood Control Act of 1958 authorized the Corps of EnSlneers to construct and operate the multiple-purpose Trinidad Dam and ~eservoir Project on the Purga- toire River about 4 miles upstream from the city of Trinidad, The purposes of the project are to provideia high degree of flood protection from the Purgatoire River to Trinidad and the agricultural areas lOcated above and below the city, a more dependable water supply for the Irrl-,' gated lands below the city, and recreational opportunities. 34. The total storage capacity of the reservoir will be 114,500 ,acre-feet, of which 59,000 Is allocate,d to irrigation and sediment reserve, 51,000 to flood control, and 4,500 acre-feet for a permanent fishery pool. If the project had bee~ in operation during the flood which occurred on the Purgatoire Riven in May 1955, over 90 percent of the damages of $1,885,000 would have been prevented. By more effective regulation and conservation of irrigation water, it is estimated that the water supply for this purpose wi I I be improved from the present average of 155 percent to an average of 84 percent of the fu II wate,r supply. Although the dam wi I I practi~al Iy el iminate flOOding on the Purgatoire through Trinidad and the highly developed agricultural area below the city, the project wi I I not have an important effect on flood peaks at the mouth of the Purgatoire River just below Las Animas. Con- ,/ structlon is scheduled to begin in 1964. ' 35. Pursuant to Publ ic Law 590, 87th Congress, the Fryingpan- Arkansas Project was author I zed for construct I on, operat i on, and maintenance by the Bureau of Reclamation. The project plan consists of a system of canals, tunnels, and reservoirs for transmountain,di- version of water from the Colorado R(ver Basin eastward through the Cont i nenta I 0 i v i de I nto the headwater's of the Arkansas River Bas In.
