Completion of this project will provide for the comprehensive utilization of the water resources of the Cumberland River below Cheatham lock and dam including navigation, flood control, and hydroelectric power production. The navigation component of this project is of major importance since existing locks on the Cumberland River below Cheatham lock and dam are obsolete and do

not provide for present needs. Some of the five crib-type dams to be replaced are 47 years old and work on the new project should progress as rapidly as pos sible before serious trouble develops. Indicative of the demand for use of the Cumberland River for navigation purposes is the continuing increase in traffic volume experienced during recent years in spite of the inadequate existing facili ties. Tonnage moved on this river at the present time, together with indicated additional traffic expected to develop, stamps the waterway as one having considerable potential toward becoming one of the more important arteries of the inland waterway system. Substantial flood control benefits to the Ohio and Mississippi Rivers will be realized by construction of the project. Recreation benefits are also significant. Hydroelectric power from the proposed installation of 130,000 kilowatts capacity will be integrated into the requirements of regions 19 and 20 of the Federal Power Commission. Power demands are rapidly expanding in this area. The addition of the project to the power system of the Cumberland-which includes the completed Dale Hollow, Wolf Creek, Center Hill, Old Hickory, and Cheatham projects, and the Cordell Hull and J. Percy Priest Reservoirs presently under construction-will enhance the dependability of the system's power output. Moreover, the value of the increased flows (regu. lated flows) from the upstream projects would be wasted without the main river power dams. In addition, provision is made in this project for a canal connecting with Kentucky Reservoir on the Tennessee River in the interest of interchange of navigation traffic and to permit utilization of the flow of both rivers to the best advantage. The canal will increase the annual electrical energy output of the Barkley project 102,200,000 kilowatt-hours. River traffic between the Cumberland River and points on the inland waterway system downstream from the Tennessee River will save approximately 20 miles by going through the Kentucky pool. Also, the canal will provide an alternative route to the Ohio and would avert a complete stoppage of river traffic which would otherwise occur in case of unavoidable closure of the Barkley or Kentucky locks.

The funds requested for fiscal year 1965 are required for orderly construction progress to permit meeting the scheduled dates for beneficial use.

Non-Federal costs.-Costs allocable to power, presently estimated at $45,963,000, are reimbursable.

Status of local cooperation.-None required for construction. Responsibility for repayment of power costs rests with the Department of the Interior pursuant to Federal laws.

Comparison of Federal cost estimates.-The current Federal (Corps of Engineers) cost estimate of $145 million is a decrease of $5 million from the latest estimate ($150 million) submitted to Congress. Total decreases of $6,899,000 resulted primarily from award of contracts for relocations; reservoir clearing; lock and powerplant equipment; reduction in contingencies on basis of advanced stage of completion of contracts; more detailed studies of requirements for lands, relocations, and supervision and administration. These decreases were partially offset by increases totaling $1,899,000 due to price level rise, award of relocation contracts, contract overruns, provision for additional dredging depth, and engineering and design costs.
