The project is one of seven reservoirs authorized for construction in the Scioto Basin. Along with
the other authorized reservoirs, including the completed Delaware and Deer Creek Reservoirs, the Alum Creek project
would help alleviate flood hazards along the Scioto River. The project would provide a high degree of protectiion
to the thickly populated and heavily industrialized East Side of Columbus along Alum Creek. This area suffered
damages in excess of $3,000,000 during the January 1959 flood, the maximum of record. The project as a unit in the
comprehensive plan for the Ohio River Basin would also reduce flood flows on the main stem of the Ohio River.
addition to flood control, the operation pool would be used for recreation and fish and wildlife and water supply.
The water supply feature is urgently needed at the earliest possible date to alleviate the shortage problem in the
rapidly expanding Columbus Metropolitan Area. Average annual benefits for the project are estimated at $6,495,400.

NON-FEDERAL COSTS: The Authorization Act requires non-federal financing of all project costs allocated to the
water supply features of the project. Local interests are to reimburse the Government an estimated $24,020,000
exclusive of interest. Reimbursement may extend over a period of 50 years, starting after storage is initiated.
In addition, local interests will be required to pay for operation and maintenance of the water supply facilities,
estimated at $34,000 annually. By letter dated 26 November 1969, State of Ohio agreed to operate, maintain and
further develop proposed recreation development. Annual costs of operation and maintenance and major replacements
for recreation currently estimated at $236,400.

STATUS OF LOCAL COOPERATION: The Water Supply Contract with the State of Ohio has been fully consummated and was
approved by the Secretary of Army on 20 June 1968.

COMPARISON OF FEDERAL COST ESTIMATE: The current Federal cost estimate of $45,400,000 is a decrease of $2,700,000 from the latest estimate ($48,100,000) submitted to Congress. Decreases consist of $500,000 in Lands and Damages based on actual costs incurred to date for implementation of PL 91-646; $2,490,000 in Relocations based on low contract bids and firm amount of Government participation in the relocation of Rt. 36 by the State of Ohio and low bid and contingency reductions on Government highway relocation contracts; and $950,000 in the Dam based on contingency reductions. These decreases were partially offset by a $825,000 price level rise; a $115,000 increase in Engineering and Design for salary increases and to comply with current standards of sanitation and water quality and $300,000 increase in Supervision and Administration based on salary increases and provision for payment of rent for building space previously paid for by the General Services Administration.

BENEFIT TO COST RATIO: The benefit to cost ratio last presented to Congress (FY 1974) was 3.0 to 1. The current
benefit to cost ratio is 3.2 to 1. The ratio is based on Alum Creek Lake being allocated a proportionate share of
the 7 reservoir system benefits on the Scioto River; and, as the next added project to the Ohio River System following
projects complete, under construction and in advanced planning stage as of 1965.

STATUS OF ENVIRONMENTAL IMPACT STATEMENTS:

The Final EIS was filed with CEQ 23 Feb 1973.

OTHER INFORMATION: Funds to initiate preconstruction planning were appropriated in FY 1966, for "Land Acquisition
Only" in FY 1968 and for construction in FY 1970.

JUSTIFICATION:

The

Caesar Creek Lake will function as a unit of the general comprehensive plan for flood control and
allied purposes in the Ohio River Basin and provide substantial reduction in flood damages along 50.4 miles of the
Little Miami River, 518 miles of the Ohio River below the Little Miami River. In addition, the reservoir will control
a drainage area of approximately 237 square miles which is about 98 percent of the drainage area of Caesar Creek.
overflow area of the Little Miami River below Caesar Creek comprises about 8,800 acres of rural lands and includes portions
of the urban areas of Newtown, Milford, Loveland, South Lebanon and Morrow and ten small communities. Between the se urban
areas are scattered developments of mostly residential and small farm properties. (Developments in the urban areas include
normal distribution of residences, businesses, services, utilities and transportation routes. Two industries in the over-
flow area are subject to inundation.) The flood of record on the Little Miami River occurred in 1913 and caused damages
amounting to $708,000 at the time of occurrence along the reach of River affected by the project. A recurrence of this
flood under present conditions of development and values would cause damages estimated at $13,572,000 of which $3,224,000
would be prevented by the project based on July 1973 values. During the last five years, damaging floods occurred along
the reach of the Little Miami River affected by the project in March 1973, December 1972, February 1971, April 1970, and
January-February 1969. The project will provide for water-associated recreational opportunities, preservation and
enhancement of the fish and wildlife resource, improvement in the quality of downstream flows, and water supply for
municipal and industrial uses. Average annual benefits for the project are estimated at $5,082,000.
