Flood problem.-The basin is subject to severe winter storms which cause flooding of agricultural and urban areas. Damages result from inundation, bank erosion, and deposition of debris and silt.

Recommended plan of improvement.-Staged construction of multiple-purpose reservoir at Knights Valley site for flood control, water supply, and recreation.

1 Includes $144,500,000 allocated to water supply and $5,850,000 allocated to recreation and fish and wildlife enhancement reimbursable by local interests.

Includes $638,000 to be repaid by local interests for water supply.
For recreation facilities which would be a non-Federal responsibility.

Benefit-cost ratio.-1.2.

Local cooperation.-Prior to construction furnish assurances they will hold and save the United States free from damages; adjust all claims concerning water rights arising from construction and operation of the improvements, including acquisition of water rights needed for preservation of fish and wildlife; reimburse the United States for that portion of the construction cost and payment of those portions of the annual charges for operation, maintenance, and major replacements allocated to water supply in accordance with the 1958 Water Supply Act, these amounts currently estimated at $144,500,000 and $638,000, respectively; administer project land and water areas for recreation and fish and wildlife enhancement; pay, contribute in kind, or repay (which may be through user fees) with interest one-half of the separable cost of the project allocated to recreation and fish and wildlife enhancement, the amount involved currently estimated at $5,850,000; and bear all costs of operation, maintenance, and replacement of recreation and fish and wildlife facilities, the amount involved currently being estimated at $144.000 annually.

Comments of the State and Federal agencies.

Department of the Interior: Although it does not object to construction of the project by the Corps of Engineers, Interior recommends that: construction be delayed until completion of its studies; initial construction be to ultimate capacity instead of in three stages; integration of the project with the Central Valley project; and operation and maintenance of the project by Interior. In reply the Chief of Engineers stated that he does not find justification for recommending irrigation as a project purpose at this time. However, it is the intent of his recommenda

tion to reconsider irrigation needs and the feasibility of single-
unit construction in the preconstruction stage. It is also the
intent of his recommendation that, at that time, consideration also
will be given to the desirability of financial integration with the
Central Valley project. Even should these studies demonstrate
the desirability of such integration, the 1958 agreement between
the Departments of Army and Interior calls for projects of this
kind to be operated and maintained by the construction agency—
in this instance the Department of the Army.

Department of Agriculture: Favorable.
Department of Commerce: Favorable.
Federal Power Commission: Favorable.
Public Health Service: Favorable.

State of California: Favorable.

Comments of the Bureau of the Budget.-No objection. Remarks.-The committee notes that the Russian River Basin is troubled by frequent flooding, is faced by potential shortages of water for municipal and industrial use, and lacks sufficient recreation areas to meet the needs of the rapidly growing nearby urban centers. The basin plan offers an excellent solution to these problems, and, since construction of Knights Valley Dam and Reservoir would further the objective of the basin plan, the committee believes that the project is meritorious for Federal undertaking.

PAJARO RIVER, CALIFORNIA

(H. Doc. 491, 89th Cong.)

Location.-The Pajaro River drains into the Pacific Ocean about 75 miles south of San Francisco. The river drains an area of 1,300 square miles. The principal tributaries at Watsonville are Corralitos and Salsipuedes Creeks with a combined drainage area of 57 square miles.

Authority.-Resolution, House Committee on Flood Control, adopted May 14, 1945.

Existing project. The existing flood control project consists of levees on the Pajaro from its mouth to right bank mile 11.8 and to left bank mile 10.6 and on its tributary, Salsipuedes Creek, to right bank mile 2.6 and left bank mile 1.7. Local interests have constructed bank protection works upstream from the Federal project. A number of natural lakes used for irrigation and water supply have been increased in capacity by construction of dams; however, they have little or no effect on flood flows.

Flood problem.-Floods in the Pajaro Valley are caused by severe rainstorms in winter and early spring. The existing project does not provide an adequate degree of protection for the area. Severe bank erosion caused breaching of the north levee above Watsonville during the floods of December 1955 and April 1958.

Recommended plan of improvement. The plan provides for modification of the existing project by raising and extending the levee system upstream to about mile 12.5 on the Pajaro River and to about mile 4.5 on Corralitos and Salsipuedes Creeks, for improvement of the outlet of College Lake on Salsipuedes Creek, and modification of four highway bridges.

Local cooperation.-Provide lands, easements, and rights-of-way, including ponding, borrow, and spoil-disposal areas; hold and save the United States free from damages due to the construction works; accomplish all modifications or relocations of pipelines, utilities, roads, bridges, and other facilities; maintain and operate all the works after completion; satisfy all claims concerning water rights arising from construction and operation of the improvements; prevent encroachment on the constructed works and ponding areas. Local interests have indicated willingness to fulfill the requirements of local cooperation.

Comments of the State and Federal agencies.

Department of Interior: Favorable.

Department of Agriculture: Favorable.
Department of Commerce: Favorable.

Department of Health, Education, and Welfare: Favorable. State of California: The State of California favors authorization subject to demonstration of economic justification prior to funding for construction.

Comments of the Bureau of the Budget.-No objection.

Remarks. The committee notes the flood hazard at Watsonville resulting from severe rainstorms along the coast in the lower Pajaro River area. The existing levees do not provide adequate protection to the development in this area. The committee also notes the evacuation of approximately 1,000 persons necessitated by the flood in December 1955 and considers the project modification essential.

SECTION 204

FLOOD PLAIN PLANNING

The purpose of this section is to amend section 206 of the Flood Control Act of 1960, as amended, which authorized the Secretary of the Army, through the Chief of Engineers, to compile and disseminate information on floods and flood damages including identification of areas subject to inundation by floods of various magnitudes and frequencies.

The basic legislation was enacted to meet a growing need at the local level for information about flood problems, damages and hazards, and measures for their amelioration. Under this authority the Corps of Engineers has established a program whereby flood plain information reports are prepared at the request of State or local interests.

The committee is informed that recently the President issued Executive Order 11296,"Evaluation of Flood Hazard in Locating Federally Owned or Financed Buildings, Roads, and Other Facilities, and in Disposing of Federal Lands and Properties." Section 3 of that order assigns to the Department of the Army responsibility for furnishing to the affected agencies information on flood hazards and flood proofing for all river basins other than that the Tennessee River.

In order to make the present flood plain information program of the Corps of Engineers applicable to Federal agencies as well as States and local interests, the committee has included language in the bill amending section 206 of the 1960 Flood Control Act. The amended language in addition will permit the Chief of Engineers to furnish certain technical services such as, publication of material on structural flood proofing and assistance in interpretation of flood hazard data for purposes of land use regulation.

The committee realizes that an expanded flood plain information program cannot be accommodated within the present authorization of $2.5 million and has accordingly increased this authority to not to exceed $5 million in any one fiscal year for the compilation and dissemination of such information. If this amount proves to be insufficient to meet the needs of Federal agencies and State and local interests for flood hazard management information, the committee should be so informed.

SECTION 205

SAVANNAH RIVER-DUKE POWER CO.

This section grants the consent of Congress for the construction of a dam across Savannah River between South Carolina and Georgia. The committee is informed that the Duke Power Co. plans a 2million-kilowatt steamplant on the Savannah River about 8 miles below Hartwell Dam and immediately upstream of Sanders Ferry Bridge. A diversion dam across the Savannah River is needed and proposed to provide cooling water for the plant. This dam would provide intake water storage for the coolant if another dam is constructed downstream.

The Savannah River in this reach is a navigable water of the United States. Because of this, authorization by the Congress is necessary to build the dam. This section provides the consent of Congress. The section includes a provision for approval of plans of Duke Power Co. by the Chief of Engineers and the Secretary of the Army before comniencement of work. It also provides among other things, that the grantee or its successors shall hold and save the United States free from all claims by reason of the future construction and operation of the authorized Hartwell Dam and Reservoir, Trotters Shoals Dam and Reservoir, or any other Federal project upstream or downstream from the dam herein authorized. Unless actual construction of the proposed dam is commenced within 12 years and completed within 15

years from the date of the approval of this act, the authority granted herein would be deemed null and void.

The section further provides that no existing or future unit at Hartwell Reservoir will be operated to pump water from below Hartwell Dam back to Hartwell Reservoir and a volume of water per week equal to at least an average flow of 1,500 cubic feet per second shall be discharged from Hartwell. Inasmuch as these requirements for discharges from Hartwell Reservoir may result in additional costs in the operation of the reservoir and in the loss of other benefits, the Secretary of the Army is authorized to determine and fix a reasonable and equitable annual charge to be paid by the Duke Power Co. to the United States as compensation for such damages.

The committee has been informed that there is no conflict between the construction proposals for the Federal Trotters Shoals project and the diversion dam which the Duke Power Co. desires to construct across the Savannah River near Middleton Shoals, and accordingly has included language in the bill authorizing the two developments.

SECTION 206

MISSISSIPPI RIVER COMMISSION

(Terms of Office of Civilian Members)

The Mississippi River Commission was established by act of Congress of 1879 and provides that three members be appointed from civil life. The members serve at the pleasure of the President and under civil service law now serve until age 70 or for 15 years, whichever comes later.

The committee feels that the Mississippi River Commission would be strengthened if the pattern for the Board of Directors of the Tennessee Valley Authority were adopted for appointing members of the Commission. Under the arrangement provided for in this section, as vacancies occur, the civilian members would be appointed for a 9year term thereby establishing staggered tenure.

The committee desires to make clear that nothing in the language prohibits reappointment to the Commission and does not affect the tenure of the present members of the Commission.

SECTION 207

SURVEYS

This is the customary section providing for authorization for surreys at various localities. It is similar to the corresponding section 105 in title I, and covers surveys at the following locations:

Watersheds and streams of Puerto Rico and the Virgin Islands, with respect to a framework plan for developing water resources of the region.

Watersheds and streams within the alluvial valley of the Mississippi River below Cairo, Ill., with respect to a framework plan for developing water resources of the region.

Watersheds and streams draining into the Great Lakes including the lake areas within the United States, and into the St. Lawrence River at points within the United States with respect to a framework plan for developing water resources of the region.
