IMPROVEMENT OF RIVERS AND HARBORS IN THE KANSAS CITY, MO., DISTRICT

This district comprises a portion of southwestern Iowa, northwestern, central, and western Missouri, northern Kansas, southern Nebraska, and a portion of northeastern Colorado embraced in the drainage basin of the Missouri River and tributaries from Rulo, Nebr., to the mouth. The report on the navigation project for the section of the Missouri River from Kansas City, Mo., to Rulo, Nebr., is included in report upon improvement of rivers and harbors in Omaha, Nebr., district.

District engineer: Col. P. D. Berrigan, Corps of Engineers, through July 23, 1950; Lt. Col. L. J. Lincoln, since that date.

Division engineer of the Missouri River Division, Omaha, Nebr., comprising the Kansas City, Mo., Omaha, Nebr., Garrison, N. Dak., Fort Peck, Mont., and Denver, Colo., districts: Brig. Gen. S. D. Sturgis, Jr., United States Army.

1. MISSOURI RIVER, KANSAS CITY TO RULO

See report on Missouri River, Kansas City to Sioux City, page 1584.

2. MISSOURI RIVER, KANSAS CITY TO THE MOUTH Location. The Jefferson, Madison, and Gallatin Rivers conjoin at Three Forks, Mont., to form the Missouri River, which flows southeasterly 2,464.4' miles across or along seven States to the Mississippi River, 17 miles above St. Louis. For description, see page 1149, Annual Report for 1932. Practically the entire length of the section from Kansas City to the mouth is contained within the State of Missouri.

Previous projects.-The first appropriation for improvement by regulation was made in the River and Harbor Act of June 18, 1878. The original plan for comprehensive improvement was adopted by the River and Harbor Act of August 2, 1882, modified by River and Harbor Acts of July 5, 1884, September 19, 1890, and June 13, 1902. For further details see page 1891 of Annual Report for 1915 and page 1153 of Annual Report for 1938.

Existing project. This provides for a channel of 9-foot depth and width not less than 300 feet, to be obtained by revetment of banks, construction of permeable dikes to contract and stabilize the waterway, cut-offs to eliminate long bends, closing of minor channels, removal of snags, and dredging as required. Length of section under improvement (mouth to upper end of Quindaro Bend) is 386.2 miles1. Ordinary and extreme fluctuations of stage are 16 and 38 feet, respectively.

The estimated cost for new work, revised in 1950, is $113,297,100, exclusive of amounts expended on previous projects. The estimated cost for annual maintenance is $2,000,000.

The existing project was authorized by the following river and harbor acts:

Local cooperation. The project provides that cooperation from benefited localities may be required, in case a comprehensive plan is adopted by Congress, for an apportionment of expense, where any improvement confers special benefit; and receipt of contributions from private parties, to be expended with Government
