1 Costs allocable to water supply are reimbursable, amount not determined ($1,263,000 when authorized).

JUSTIFICATION

The Big Hill Dam would provide a high degree of flood protection to 4,510 acres in the upper reaches and would provide a moderate degree of protection to 6,030 acres of lands in the flood plain common to Big Hill Creek and the Verdigris River. The total annual crop value for the 10,540 acres is estimated to be in excess of $465,000 and the value of property, including minerals, is in excess of $4 million.

Non-Federal costs. In accordance with the Water Supply Act of 1958, the State of Kansas or local interests would be required to repay to the United States all costs allocated to water supply, and also pay the annual cost of operation and maintenance chargeable to water supply.

Status of local cooperation. The proposed repayment requirement for water supply storage has been discussed with local and State interests. The cities of Coffeyville and Cherryvale, Kans., have each furnished resolutions indicating willingness to assume the responsibility of repayment of the allocated water supply costs.

Comparison of Federal cost estimate. The current Federal cost estimate of $4,100,000 is the same as last presented to Congress.

LAS CRUCES LOCAL PROTECTION PROJECT, NEW MEXICO
(Continuation of planning)

Location and description. The project is comprised of two dams, Las Cruces Dam, which extends across Alameda and Las Cruces Arroyos; and Campus Dam, relatively small in size, which is located on Campus Arroyo. Las Cruces Dam located about 1,000 feet east of the city limits will be of earthfill construction with both slopes protected. Campus Dam will be small earthfill structure located on Campus Arroyo immediately upstream from the campus of the State university. Uncontrolled outlets will be provided in both dams. An outlet channel on Alameda Arroyo will carry discharges from Las Cruces Dam to the Rio Grande. Releases from Campus Dam will be discharged into Campus Arroyo. Authorization.-1962 Flood Control Act. Benefit-cost ratio.-1.7 to 1.

Practically the entire city of Las Cruces and the surrounding suburban area, including the campus of the New Mexico University of Agriculture, Engineering, and Science, have intermittently suffered severe damages from the arroyos which head on the western slope of the Organ Mountains or on the alluvial outwash plain, and flow westward toward the Rio Grande. The principal damageproducing streams are Las Cruces and Alameda Arroyos and to a lesser degree,

Campus Arroyo, which drains into the university campus. There is also considerable damage from overbank flow, sheetflow, and ponding caused by other arroyos which have no outlet to the Rio Grande. The overflow area of the standard project flood plain contains about 5,940 acres of which about 1,005 acres are urban and suburban lands, 4,550 acres are irrigated and cultivated, and 385 acres are adapted to other uses. The estimated value of all lands and improvements in the flood plain amounts to about $83,508,000 (1963 conditions and prices). The most damaging flood, for which dependable data are available, occurred on August 29-30, 1935, and flooded about 720 acres of land including 290 acres of residential and commercial properties and 430 acres of farmland. This flood caused an estimated $220,000 damages (1935 prices) to residences and commercial properties including three schools. A recurrence of the 1935 flood under present prices and conditions would cause damages estimated at about $1,798,000, of which an estimated $627,900 damages would be prevented with the project in full operation. A flood of standard project magnitude would inundate the flood plain to an average depth of 2 feet and a maximum depth of feet. Estimated damages from the standard project flood under present conditions would amount to over $8,657,000. The funds requested for fiscal year 1965 will permit completion of preconstruction planning.

Non-Federal cost. The investment required of local interests in construction of the authorized project is estimated at $536,000, broken down as follows:

Local interests are required to maintain and operate the project upon completion. It is estimated that the average annual expenditure for maintenance and operation will be $8,640.

Status of local cooperation. The city of Las Cruces proposes to finance required local cooperation through issuance of general obligation flood control bonds. Bond election can be held during the regular city election in January 1965. The mayor of Las Cruces has been furnished preliminary plans of the project setting forth the general features of the project and the requirements of local cooperation. Formal assurances will be requested upon completion of the general design memorandum.

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

JUSTIFICATION

The primary purpose of the reservoir would be flood control, water conservation, recreation, and fish and wildlife. Floods have occurred about once a year along the Arkansas River in the vicinity of Ponca City, Okla. Operation of this reservoir would provide protection to about 39,310 acres of land downstream to the Keystone Reservoir. Flood losses are sustained by farm improvements, county roads, highways, oilfields, and refineries. Total flood damage reduction benefits are estimated at $1,128,000 annually. In addition to providing flood protection, the project has 232,000 acre-feet of storage allocated to industrial and municipal water supply. Operation of the Kaw Reservoir would reduce accumulation of sediment in the Keystone Reservoir thereby increasing the usefulness of that project for all purposes. This is especially important since Keystone Reservoir is a key project in the multiple-purpose plan of improvement for the Arkansas River and tributaries.

Non-Federal cost.-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. The reimbursement required has not been determined ($13,500,000 estimated at time of authorization).

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. State and other local interests have indicated intent to meet these requirements as evidenced by assurances adopted by the Oklahoma Water Resources Board, the Kaw Dam and Reservoir Development Association, Inc., and the city of Ponca City, Okla.
