JUSTIFICATION: The project will protect 157,250 acres of valley lands now subject to periodic inundation from
floods originating on the upper Guadalupe River. Considerable development has taken place in the flood plain of
the Guadalupe River in recent years, much of which is concentrated in the area subject to inundation by major
floods in the vicinity of Seguin and New Braunfels. The last serious flood occurred during Apr-May 1958, causing
damages estimated at $3,571,000 at then prevailing prices, in the area benefited by the project. A recurrence
of this flood under present conditions of development and price levels would cause damages estimated at
$3,813,000, of which $3,432,000 would be prevented by the project. Comal Springs at New Braunfels (formerly the
largest springs in the Southwest) have a normal flow of about 250 second feet. During the drought that ended in
the Spring of 1957, the springs almost ceased flowing, causing a critical shortage of water downstream on the
Guadalupe River. Although the flow of Comal Springs is now about normal, future periods of below normal flow
can be expected to recur. Existing business and industries located along the Guadalupe River from New
Braunfels to the mouth, which are dependent upon the flow of Comal Springs, include steam-electric generating
plants, hydroelectric generating plants, recreational facilities, and chemical processing plants. Munici-
palities along the river also depend upon the river flow for their water supply; and there is a considerable
acreage in rice irrigation near the mouth of the river dependent upon this flow. The increased net dependable
flow from Canyon Reservoir (about 150 second-feet) will greatly alleviate future water shortages caused by below
normal flow from Comal Springs.

FISCAL YEAR 1962: The requested amount of $3,000,000 will be applied to:

Continue acquisition of lands

Initiate and complete reservoir clearing
Continue relocation of roads

Continue construction of earthen embank. and spillway
Continue construction of operation and maintenance

CANYON RESERVOIR, TEXAS (Cont'd)

Funds requested for FY 1962 are considered to be the minimum amount required in order to meet the scheduled date of dam closure.

NON-FEDERAL COSTS:

Local interests are required to pay the cost of the dam and reservoir allocated to water conservation and stream-flow regulation, and to hydroelectric power if power facilities are provided by local interests. The construction costs allocated to local interests shall be not less than $1,400,000, which amount shall be contributed by local interests during construction, and the remainder of the construction costs allocated to local interests shall be repaid with interest at the rate of 2-1/2 per cent per annum within fifty years. Local interests are also required to pay allocated portion of the operation and maintenance costs.

STATUS OF LOCAL COOPERATION:

A formal contract with the Guadalupe-Blanco River Authority embodying the requirements of local cooperation was approved by the Chief of Engineers on 24 October 1957. The GBRA has contributed $700,000 to date.

COMPARISON OF FEDERAL COST ESTIMATES: The current Federal cost estimate of $17,300,000 is an increase of $600,000 over the latest estimate ($16,700,000) submitted to Congress. The increase includes $184,000 for Lands and Damages based on a reanalysis of requirements; $146,000 based on price level rise; and $229,000 in Recreational Facilities and $68,000 in Supervision and Administration, both based on a reanalysis of requireThese increases were partially offset by a net reduction of $27,000 in other features based on more detailed engineering studies and design.
