o ) N ~ N -.J accordance with law, the Division Engineer referred the report for, review to the Board of Engineers for Rivers and Harbors in Washington, D.C. Subsequent to submission of the report to the Board, the prescribed interest rate for projects of this type was changed from 3-1/4 percent to 4-5/8 percent. This has necessitated a reanalysis of the feasibility and formulation of the plan of improvement outlined above and in the Notice of Report. In addition to this reanalysis, the reporting of- ficers are presently making supplemental studies to determine the feasibility of providing a higher degree of protection to the urban area of Pueblo by reservoirs in the Fountain Creek watershed, as recom- mended by the Division Engineer in the Notice of Report, in order to present a definite pian of improvement to Congress. The results of these studies will be incorporated in the recommendations of the Divi- sion Engineer, and he will issue a revised Notice of Report. Studies of the effects of the application of the new interest rate on the recommended projects are underway by the Albuquerque District, and preliminary findings indicate that a number of the projects pre- viously recommended will not be economically justified. Further information regarding the results of these studies will be fUl~ished to all interested parties in the near future. Supplemental studies of the Fountain Creek flood problem are under- way to determine whether a higher degree of flood protection for the city of Pueblo would be justifiable. Alternative plans being con- ' sidered include a concrete-lined channel with a capacity of 125,000 cubic feet per second for protection against a flood with a frequency of occurrence of once in 100 years, and a multiple-purpose reservoir project on Fountain Creek located about two miles north of the Pueblo ci ty limits 0 Although the channel improvement project appears to be feasible, the reservoir project would provide a higher degree of flood control and, in addition, it would provide a permanent pool for recX'eation, fish and wildlife enhancement. Also, the State of Colorado has ex- pressed an interes;: in the establishment and maintenance of a permanent pool of 20,000 acre-feet under provisions of Federal Water Projects Recreation Act (Public Law 89-72). Under provisions of this Act, non- Federal public bOdies would be required to administer proj ect land and water areas for,recreation and fish and wildlife enhancement purposes and operate, maintain, and replace facilities provided for those purposes. In addition, local interests would bear not less than one- half the separable cos'i:s allocated to :recreation, fish and wildlife. The dam under study consists of an earthfill structure approximately 12,000 feet long with a crest width of 20 feet, rising 172 feet above the streambed. The dam would create a reservoir about 5 miles long. The total storage capacity of the reservoir at spillway crest would be 3 ,,~ ,~ '
