, ~, In 1952, pursuant to Section 14 of the 1946 Flood Control Act, emer- gency bank protection was provided for valuable farmland and a county road which were being destroyed by meandering of the river north of the town. The work consisted of the excavation of a pi lot channel about 6,000 feet long across an oxbow and the construction of a diversion dike at the upstream end to divert flows into the river channel. The Fed- eral cost amounted to $25,600. In 1956, the pi lot channel was extended about 9,300 feet upstream at an additional Federal cost of $35,800. This work was authorized in accordance with Section 15 of the 1946 Flood Control Act. The city of Las Animas later extended the pi lot channel downstream for a distance of about 10,500 feet to the AT&SF Ra i I way br i dge . 29. The only other Federal agency that has constructed water resources improvements in the Arkansas River Basin in Colorado is the Soi I Conservation Service. This agency, in addition to the regular land treatment program carried on through organized Soi I Conservation Districts, has constructed or contemplates construction of a number of floodwater retarding structures under the watershed program authorized by the Watershed Protection and Flood Prevention Act (Publ ic Law 566, as amended). In the upper watershed of Big Sandy Creek above Limon, 13 structures have been completed and one is under construction. One structure, designated by the Soi I Conservation Service as FPCA No.2, has been completed and another (FPCA No. I) is being bui It in the Fishers Peak-Garbon Arroyos watershed near Trinidad. Part of the city is included in the project area and wi II benefit by the protection afforded. Four structures are planned in the Vine land area about 10 mi les east of Pueblo. A watershed Work Plan for three retardation dams has been approved for Limon Creek, a tributary to the Big Sandy. A plan for floodwater retarding structures and channels on Cheyenne Creek, near the Colo.-Kans. State I ine, is being prepared. 30. There are more than 200 smal I reservoirs constructed by local interests in the Arkansas River Basin in Colorado. These reservoirs are primari Iy for irrigation storage but they also provide local flood control and domestic and industrial water supply. The largest of these is the Great Plains Reservoirs system, a series of off-channel reser- voirs located northeast of John Martin Dam. This system has an aggre- gate capacity of 100,000 acre-feet. Others are Adobe Creek Reservoir on Adobe Creek with a capacity of 62,000 acre-feet; Cucharas and Two Buttes Reservoirs on Cucharas River and Two Butte Creek, each with a capacity of 40,000 acre-feet, and Horse Creek Reservoir on Horse Creek. 31. The only major flood control improvements constructed by local interests in the Arkansas Basin are the Barrier Dam and Pueblo Floodway. These improvements were bui It on the Arkansas River in 1924-25 by the Pueblo Conservancy District which was organized soon after the disastrous flood of 1921 for the purpose of providing flood protection to the city of Pueblo. The floodway is a concrete trape- zoidal channel approximately 10,000 feet long extending through the II
