Continuation of the work without further delay will also make possible the salvage of much of the original work which is of significant value, amounting to about $16 million in the Blair-Omaha reach alone. Full stabilization of this latter reach is of vital importance to the protection of the Omaha-Council Bluffs floodprotection project. Non-Federal costs.-No local cooperation required. Since private interests have not been able to commercially utilize the waterway, only about $600,000 has been expended to date in terminal facilities. Local interests, however, are planning eventual large expenditures along the river, such as wharves, docks, grain elevators, fabricating plants, molasses, and oil terminals. The cost of these facilities cannot be estimated at present since many are still in the planning stage. Mr. RABAUT. Insert, also, a table showing allocation by reaches.

We come to "Missouri River, Kansas City to mouth," page 25. Put pages 25, 26, and 27 in the record. (Information referred to follows:) CONSTRUCTION, GENERAL-CHANNELS AND HARBORS (NAVIGATION) MISSOURI RIVER, KANSAS CITY TO MOUTH (9-FOOT PROJECT) (Continuing) Location.-Navigable channel extending from Kansas City, Mo., to the mouth, a distance of 386.2 miles. Authorization.-1945 River and Harbor Act. Benefit-cost ratio.-1.53 to 1. for entire project Sioux City to the mouth. Channel: Channel 9 feet deep, 300 feet wide, extending from mile 386.2 at Kansas City, Mo., to the mouth, to be obtained by revetment of banks, construction of permeable dikes to stabilize the waterway, cutoffs, and dredging. The project is an essential part of the comprehensive plan for the development of the Missouri River Basin. The project will stabilize the banks of the river throughout the entire length of the project and will provide a navigable channel for waterborne commerce. Stabilization of the banks of the river from Sioux City to the mouth will insure protection against erosion to agricultural areas totaling over 1,800,000 acres and to municipalities, industries, and other installations with a value of about $2 billion. These installations include major railroad and highway bridges which receive vital protection against being flanked by the meandering river. Stabilization will also permit the construction of levees under the flood-control authorization with assurance they will not be destroyed by the erosive action of the river. The control works by which the river will be stabilized are subject to destruction by the river until the concave banks are fully stabilized. Delay in accomplishing the necessary control work at the proper time results ultimately in increased costs, since the training structures remain vulnerable to damage by ice runs and floods until given proper reinforcement. Whenever it is necessary to defer essential work, maintenance costs of the project automatically increase owing to the necessity of undertaking temporary emergency measures until the final control works can be installed. For example, existing control works at one location, where an abrupt horseshoe bend exists in the river (Jackass Bend, mile 343), have deteriorated and have been damaged by recent severe floods to the extent that it is impractical to attempt to further maintain the existing alinement in this bend. Consequently, a major realinement with attendant dike and revetment construction will be required. This realinement is most essential to properly stabilize the banks at this location and provide a satisfactory channel for navigation as well as a more feasible alinement for construction of the proposed agricultural levee unit under the flood-control authorization. Traffic surveys made in 1950 indicated 4 million tons are potentially available for commercial transportation on the river from Sioux City to the mouth. This estimate was increased 25 percent to a total of 5 million tons annually as allowance for future developments. In addition to the outbound movement of important commodities of grain and grain products, there are increased demands for inbound movement of other commodities essential to the welfare of the region. Steel firms in the Kansas City and Omaha areas have in recent years steadily increased their demands for barge movements of steel, the demands being greatly in excess of the available water transportation service. Similar demands for barge movement of steel pipe, tinplate, sugar, rice, and molasses is evidenced by the movement of these products upstream to Kansas City and Omaha during the 1955 season by private towing firms. Similar requirements are developing for barge service for petroleum, sugar, fertilizer, and coffee. The navigation season of 1955 shows a continued increase of interest in Missouri River navigation as evidenced by the increase in tonnage transported, the expansion of dock and transfer facility operations, and extensive investigauons being conducted by local interests in locating and planning for future docks. Private carriers transported 49,285 tons in 1952, 152,001 tons in 1953, 297,149 tons in 1954, and more than 400,000 tons in 1955 on this section of the river.

Non-Federal costs.-Local interests have contributed $644,000 toward the cost of the project. In addition, it is estimated that local interests have incurred costs of about $3 million for the construction of dock and transfer facilities along this section of the Missouri River and present indications are that they will incur additional costs of about $1,800,000 in the construction of additional dock and transfer facilities. The latter amount is considered conservative in view of the annual potential tonnage available for commercial transportation on this section of the river. Mr. RABAUT.

Put pages 39, 40 and 41 in the record. (Information referred to follows:) CONSTRUCTION, GENERAL-LOCAL PROTECTION PROJECTS (FLOOD CONTROL) LITTLE SIOUX RIVER, IOWA (Continuing) Location.-Along the Little Sioux River and its tributaries in Monona and Harrison Counties in northwestern Iowa. PHYSICAL DATA Levees: Average height: 12 feet. Length: 138 miles. Flood walls: None. Relocations: Raise 1 and raise and extend 2 Chicago & Northwestern Railroad bridges. Channels: 34 miles of enlargement and straightening on main stem. 35 miles of enlargement and straightening on tributaries. Pumping plants: None. The Little Sioux project is urgently needed to provide flood protection to the lower portion of the Little Sioux Basin which is subject to frequent and prolonged damaging floods. The extremely flat slope of the stream channels in this area retards the flows of water, and the flat slopes of the adjacent lands, roads, grades, and ditch spoil banks, prolongs the period of flooding. The project will protect approximately 120,500 acres of very productive, highly developed farmland, including 340 farmsteads from damaging floods. In addition, essentially all of the towns of Hornick, Holly Springs, and Luton, and a part of Turin are subject to comparatively frequent flooding, and a part of River Sioux, Blencoe, Onawa, Whiting, and Sloan are subject to flooding by more severe floods. The proposed project would provide protection against all past floods of record. It would have prevented estimated damages in excess of $2,500,000 from the flood of March-April 1951, the greatest flood of modern record in this area. Flood damages resulting from June 1954 flood in the entire Little Sioux Basin have been estimated at $3,200,000. Annual flood-control benefits are estimated to be $971,900. Drainage districts are organized to assume the requirements of local cooperation. Formal assurance will be furnished upon completion of certain legal steps required by Iowa law.
