Project cost estimate Comparison of Federal cost estimates.-No change from the latest estimate submitted to Congress. Summary construction program (PB−1), fiscal years 1964 and 1965 Item Location. The project is located on Caddo River, a tributary of the Ouachita River in Hot Spring and Clark Counties, Ark., about 10 miles north of Arkadelphia, Ark. Authorization.-1950 River and Harbor Act and 1958 Water Supply Act. The project will provide complete flood protection to the area along Caddo River immediately below the dam, and reduce the frequency and duration of flooding on 191,000 acres along the Ouachita River. For large floods, stages on the Ouachita River at Arkadelphia will be reduced about 2 feet in addition to the reduction provided by Blakely Mountain Dam. The flood of April-May 1958 caused damages amounting to $582,000. Should this flood be repeated under present condition assuming DeGray Reservoir complete, damages totaling $192,000 would be prevented. In addition, the project will provide 91,100,000 kilowatthours of power annually and a reliable source of water supply for industrial and municipal use. During critical low-flow periods the project will provide an amount of water which will assist in alleviating pollution from oilfield and industrial waste, and will also benefit navigation downstream on the Ouachita River. Fiscal year 1965.-The requested amount of $7,100,000 will be applied toInitiate: The requested amount is necessary to continue construction in a logical and orderly sequence. Funds are required for (a) initiation of main embankment so that this item will be advanced to where initial reservoir filling can be started in July 1968 to meet scheduled power-on-line dates; (b) start manufacture of intake cylinder gate so delivery can be made by the time needed for installation by prime contractor for intake structure; (c) continuation of land acquisition so as not to delay starting construction of dike and main embankment; (d) continuation of relocations so that they will not interfere with construction of dike and main embankment; (e) continuation of construction of tunnel and stilling basin in order to effect diversion of the river in June 1965 when needed for main embankment construction; (f) continuation of manufacture of turbines and start manufacture of generators and governors in order that design data will be available in time for detailed design of powerhouse; (g) completion of dam fault stripping prior to award of contract for main embankment; and (h) completion of reservoir clearing survey to establish clearing limits needed in connection with land acquisition and design of recreation facilities. Non-Federal costs.-Local interests are required by the Water Supply Act of 1958 to reimburse the Federal Government for the costs allocated to water supply storage. This reimbursement is presently estimated at $4,100,000, exclusive of interest. The Federal Government will be reimbursed an additional $20 million through the sale of power. The total cost of maintenance, operation, and care of the project after completion is estimated at $370,000 annually, of which local interests' share is estimated at $22,000. Maintenance will be the joint responsibility of the Federal Government and local interests. Status of local cooperation.-Local interests, under the name of Ouachita River Water District, formed a water supply district on January 28, 1959, under Act 114 of the 1957 Acts of the General Assembly of the State of Arkansas, to purchase water from DeGray Reservoir. The water district has executed assurances that they will enter into a contract or contracts for the purchase of water from DeGray Reservoir. 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 cost estimate of $50 million is an increase of $700,000 over the latest estimate ($49,300.000) submitted to Congress. This change includes an increase of $847,000 for higher price levels which was partially offset by a net decrease of $147,000 in feature estimates based on more detailed planning of construction and a recent reanalysis of requirements.

NARROWS RESERVOIR, ARK., ADDITION OF THIRD GENERATING UNIT (Continuing) Location.-On the Little Missouri River in Pike County, Ark., about 5 miles north of Murfreesboro, Ark. In operation: 2 units at 8,500 kilowatts: 17,000. Presently planned: Addition of 1 unit at 8,500 kilowatts. Normal average head: 133 feet. Status (January 1, 1964).—Third unit, not started. Completion schedule.-Power on line and third unit, March 1968. JUSTIFICATION The addition of a third generating unit is justified on the basis of a statement from the Southwestern Power Administration that they have executed a new contract marketing the additional output of a third unit. Average annual power revenues will amount to an estimated $68,000. Fiscal year 1965.-The requested amount of $350,000 will be applied to Funds are required to continue the contract for the turbine and to initiate the contracts for the generator and governor as the manufacturer's drawings are necessary for detail design of the third unit installation. Non-Federal costs.-The cost of third unit presently estimated at $1,410,000 is reimbursable through sale of power. Status of local cooperation.-None required for construction. Responsibility for repayment of power costs rests with the Department of Interior pursuant to Federal laws. Comparison of Federal cost estimates.-The current Federal cost estimate of $1,410,000 is an increase of $50,000 over the latest estimate ($1,360,000) submitted to Congress. This change is due to higher price levels. Summary construction program (PB−1), fiscal years 1964 and 1965 OPERATION AND MAINTENANCE, GENERAL Mr. WHITTEN. Now take up operation and maintenance, general, and insert the justifications in the record at this point. (The justifications follow :) 1. Navigation JUSTIFICATION OF ESTIMATE (a) Channels and harbors.-The budget estimate of $10,427,000 provides for essential maintenance work on 16 channel and habor projects named in the list which follows. The work to be accomplished under this activity consists of maintaining the navigation channels and harbors and anchorages of coastal harbors and waterways by means of dredging repair bank stabilization works, and repair and operation of navigation structures; all as authorized in the laws adopting river and harbor projects. |
