Fiscal year 1965.-The requested amount of $17,697,000 will be applied to

[blocks in formation]

The amount of funds requested for fiscal year 1965 is required to continue construction at an orderly and economical rate.

Non-Federal costs.-Local interests are required to reimburse the Federal Government for costs allocated to water supply storage, over a period not to exceed 50 years after use of this storage is initiated. This reimbursement is presently estimated at about $9,692,000 exclusive of interest.

Status of local cooperation.-Local cooperation required is limited to repayment of costs allocated to water supply features of the project under contracts to be negotiated at the proper time. A contract with the Southwest Arkansas Water District for repayment of water supply costs was approved on March 27, 1961, by the Secretary of the Army.

Comparison of Federal cost estimates.-The current cost estimate of $50 million is a decrease of $5,700,000 from the latest estimate ($55,700,000) submitted to Congress. This change includes decreases of $1,700,000 for lands and damages based on completed acquisition and appraisals, $4,033,000 for relocations based on contract awards, and more detailed planning, $468,000 for engineering and design and supervision and administration, partially offset by increases of $501,000 for other construction features based on reanalysis of requirements.

The Council Grove Reservoir is an important unit in the four-reservoir system on the Upper Grand (Neosho) River Basin. This unit, when completed, will benefit about 240,400 acres of very fertile and highly developed agricultural lands and 2,800 acres of urban area. About 14,600 persons reside within the flood plain of the Cottonwood and Grand (Neosho) Rivers, above Pensacola Reservoir, of which over 11,400 reside in the area downstream from the Council Grove Dam site. The estimated value of lands and improvements within the flood plain below

the Council Grove project is $191,813,000. The reduction in flood frequency will permit more intensive farming on 188,900 acres of cleared land, and when operating in the four-reservoir system will mitigate pollution of a major water supply source in municipal and rural areas where large sums have been expended in unsuccessful attempts to alleviate water shortages that have occurred in the basin during prolonged drought periods. Based on the present approved plan, the Council Grove Reservoir will provide 11 percent of the total flood control storage in the system of four reservoirs. The annual flood control benefits which would be realized by operation of the four-reservoir system are estimated to be $3,236,400, of which $431,500 is assigned to Council Grove Reservoir.

The funds requested for fiscal year 1965 will complete the project. Non-Federal costs.-Local interests are required to reimburse the Federal Government for costs allocated to water supply storage, over a period not to exceed 50 years after use of this storage is initiated. This reimbursement is presently estimated at about $1,395,000, exclusive of interest.

Status of local cooperation. The cities of Council Grove and Emporia, Kans., have furnished resolutions requesting the Corps of Engineers to include water supply storage in the project for their future water supply needs. These resolutions provide the assurances for repayment of the costs allocated to water supply storage required by the Water Supply Act of 1958, as amended by section 10 of Public Law 87-88. Of the total storage of 114,000 acre-feet, 24,400 acre-feet has been allocated for the future water supply use of the two cities.

Comparison of Federal cost estimate.-No change from the latest estimate submitted to Congress.

The project is an integral unit in the six-reservoir system in the Verdigris River Basin consisting of authorized Elk City and Neodesha Reservoirs, completed Fall River, Hulah, Toronto, and Oologah Reservoirs. Construction of this project is the next logical step in completing the six-reservoir system, which will, upon completion, provide urgently needed flood protection for farmlands and urban areas in both the Verdigris and Arkansas River flood plains. Operation of the

Elk City project in conjunction with the completed and under construction reservoirs would provide adequate low-flow releases for realization of pollution abatement and supplementary water supply benefits. Drought conditions throughout the Southwest in 1952-56 have greatly emphasized the need for water supply and low-flow stream regulation. It is estimated that had this reservoir been in operation, $1,640,000 of flood damages would have been prevented during the flood of May 1961 alone.

Non-Federal costs.-Local interests are required to reimburse the Federal Government for costs allocated to water supply storage, over a period not to exceed 50 years after use of this storage is initiated. This reimbursement is presently estimated at about $1,950,000, exclusive of interest.

Status of local cooperation.-The cities of Independence and Coffeyville, Kans., have each expressed an interest in obtaining storage space in the project to yield 5 million gallons per day for future water supply use. The Kansas Water Resources Board has furnished a resolution requesting a minimum of 24,300 acrefeet of water supply storage in the project, which would provide the requested yield of 10 million gallons per day.

Comparison of Federal cost estimate.-No change from the latest estimate submitted to Congress.
