~ city. Its present capacity is about 110,000 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 acre-feet at spi I Iway 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 been in place prior to the 1921 flood, the flood peak at Las Animas would have been reduced from IB7,000 c.f.s. to 140,000 c.f.s. 32. Local flood protection works of smaller scope have been con- structed by local interests on Fountain Creek at Colorado Springs and Wi Id Horse Creek at Holly. These improvements consist of diversions, floodways, channel improvement, and levees. , 33. AUTHORIZED WATER RESOURCES DEVELOPMENT.- The Flood Control Act of 1958 authorized the Corps of Engineers to construct and operate the multiple-purpose Trinidad Dam and Reservoir Project on the Purga- toire River about 4 mi les upstream from the city of Trinidad. The purposes of the project are to provide a 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 irri- gated lands below the city, and recreational opportunities. 34. The total storage capacity of the reservoir wi I I be 114,500 acre-feet, of which 59,000 is al located to irrigation and sediment reserve, 51,000 to flood control, and 4,500 acre-feet for a permanent fishery pool. If the project had been in operation during the flood which occurred on the Purgatoire River 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 65 percent to an average of 84 percent of the ful I water supply. Although the dam wi I I practically el iminate flooding on the Purgatoire through T,-inidad 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- struction is scheduled to begin in 1964. 35. Pursuant to Publ ic Law 590, 87th Congress, the Fryingpan- Arkansas Project was authorized for construction, operation, 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 River Basin eastward through the Continental Divide into the headwaters of the Arkansas River Basin. This multiple-purpose project wi I I provide supplemental water for irrigation, municipal and industrial uses, power generation, flood and sediment control, and recreation. Pueblo Dam and Reservoir, the terminal storage faci lity, wi I I be located on the Arkansas River about 6 mi las west of the city of Pueblo at approximately the same site as 12
