0022' '; --- . !:-. Wauneta, Nebraska. FollCl'ling the 1956 flood on Frenchman Creek below the Enders Reservoir, a request "as made for a small flood control project for the protection of Wauneta, Nebraska (1960 population 794). A local protection scheme was developed and presented to the city officials for their consideration. However, no further action has been taken because of the lack of assurance of local cooperation. d. Middle-basin area. The frequency and severity of flooding in the valleys of Beaver, Sappa, and Prairie Dog Creeks is indicated by the flood histories in paragraph 7. Flood damage surveys, fre- quency studies and economic evaluations have been made in these valleys "ith the cooperation of local interests who have expressed their desires for flood protection on numerous occasions and partic- ularly following the 1957 floods. In each of these valleys, the Bureau of Reclamation has plans for multiple-purpose reservoir projects which will provide flood control storage and a high degree of protection for the do,"'stream flood plains. The Norton Reservoir, located on Prairie Dog Creek, about three miles upstream from Nor- ton, Kansas, is under construction and scheduled for completion in the fall of 1964. This reservoir will provide irrigation, flood control, and municipal water supply storage. On Beaver Creek, the Bureau is preparing a feasibility report, scheduled for completion in fiscal year 1964, of the Herndon Dam and Reservoir project to be located about one mile upstream from Herndon, Kansas. Also scheduled for completion in 1964 is a reconnaissance investigation along Sappa Creek, including the proposed Oberlin Dam and Reservoir project about four miles upstream from Oberlin, Kansas. E.. Republican River main stem. The major unresolved flood problem and the issue of primary discussion at the public hearings is the channel deterioration of the main stem of the Republican River during the past decade. This is generally referred to as . "the willow problem," as the most obvious change is the rank growth of willow and other trees and underbrush within the river .banks, during the recent drought period. Problem areas lie chiefly between the Trenton Dam and Harlan County Reservoir and below the Harlan County Dam to the vicinity of Clay Center, Kansas. 16. SOLUTIONS CONSIDERED Most of the flood problems in the Republican River basin have been solved, reduced, or will be resolved by projects under con- sideration. The outstanding problems, and those, therefore, with which this investigation is primarily concerned, are the channel capacity and bank erosion on the Republican River proper below Trenton and Harlan County Dams. During the past decade, there has been an unusual growth of willows and other vegetation on and within the streambanks and a loss in channel capacity. Since there . 21
