2 Other includes fish and wildlife and recreation. Fish and wildlife reimbursables, $2,861,000 (nonreim. bursable $13,770,000) and recreation $250,000.

Adjusted from project cost by addition of Corps of Engineers' work and exclusion of distribution systems repaid by separate contracts, Friant Fish Hatchery pipeline and rehabilitation of Shasta generators, and minor revisions in the cost of the project made subsequent to the cost allocation.

The purpose of the project is to redistribute the water resources of the Central Valley since the northern portion, drained by the Sacramento River, contains approximately one-third of the land area and has two-thirds of the available water. The southern portion of the valley drained by the San Joaquin River has the reverse situation. The water supply made available by the project is used for new and supplemental irrigation, municipal and industrial consumption, and for the generation of hydroelectric power. Flood control, recreation, navigation, and fish and wildlife protection are other products of the project.

Trinity River division

WORK PROPOSED, FISCAL YEAR 1959

Trinity Dam and facilities, $26,226,000.—This amount is required primarily for contractor's earnings on the prime contract, reservoir clearing, land and land rights, and county road relocation.

Whiskeytown Dam and Reservoir, $200,000.-This program provides for surveys, investigations, and collection of field data for dam and continuing surveys for county road relocation.

Lewiston diversion dam, $300,000.-The program provides for collection of design data, preparation of designs and specifications and award of contract late in the fiscal year.

Lewiston fish facilities, $250,000.-This item provides for handling and transportation of fish and for development of additional field data, preparation of specifications and award of contract for the fish hatchery late in the fiscal year. Clear Creek tunnel, $14,266,000.-This amount required primarily for contractor's earnings on the prime contract and contractors' earnings on associated minor construction and supply contracts.

Spring Creek tunnel, $300,000.-This sum provides for surveys and collection of field data and includes a small amount for acquisition of land and land rights. Sacramento River division

Corning Canal and facilities, $887,000.-The program provides for minor completion work on Corning canal which is virtually complete but nonoperative, as well as for initiation of construction on Corning pumping plant.

American River division, $102,000.-This sum is needed for preliminary investigations of the El Dorado Irrigation District distribution system.

Project general

Water Rights (Sacramento and San Joaquin Rivers), $127,391.-Riparian land delineation, analysis of data on use of water from the Sacramento River, its tributaries, and the Sacramento-San Joaquin Delta will continue. Activities will also be continued, as required, on the cooperative program covered by the "Memorandum of understanding relating to a general approach to negotiations for settlement of water diversions from the Sacramento River and the Sacramento-San Joaquin Delta with the objective of avoiding litigation." The program also provides for litigation, negotiation, and settlement of water right claims of landowners along the San Joaquin River.

Central Valley waterfowl conservation, $137,756.—This program continues the activity under Public Law 674, 83d Congress (68 Stat. 879). These funds are required to complete the slough levee and ditch at the Mendota pool.

Delta division, $481,931.-This amount needed for collection of field data required for designs and specifications of freeboard correction on Delta-Mendota Canal with contract to be awarded in the third quarter of fiscal year 1959.

Friant division

Friant-Kern Canal, $49,459.-This program consists primarily of furnishing and installing measuring devices for Stone Corral, Teapot Dome, Saucelito, and Terra Bella Irrigation Districts. Included in this item is an amount for lower cost canal lining.

Friant-Kern distribution systems, $935,038.-For further construction of extensions to unit No. 1 of the Southern San Joaquin Municipal Utility District, to virtually complete the Shafter-Wasco distribution system; and if repayment contracts are executed, to initiate construction of the distribution systems for the Stone Corral and Teapot Dome Irrigation Districts.

Consolidated expenditures and credits-$116,575.-Represents a net increase of $55,000 stores and investigations expenditures and an offset by a credit of $171,575 covering equipment transfers, Solicitor's costs, transfers to other projects, and service facilities and balancing adjustments.

The increase in total estimated obligations of the Central Valley project is due to revised cost estimates on Trinity division features which reflect the higher bid prices received on Trinity Dam and Clear and Spring Creek tunnels, the inclusion of distribution systems for Teapot Dome and El Dorado irrigation districts, the extensions to unit No. 1 of the Southern San Joaquin Municipal Utility District distribution system, and the increased cost estimate for corrective work on the Columbia-Mowry canal system.

TRINITY RIVER DIVISION

Mr. CANNON. On the Trinity River division, please explain the basis for the increase in cost from $225 million to $262 million since last year, and a reduction in the benefit-cost ratio from 3.3 to 1 to 1.38 to 1. Mr. BENNETT. The increase in construction cost is the result of our analyzing the bids received or bids that have been let and also of indexing the remaining work, which raised it from $225 million to $262 million.

Mr. CANNON. That is an increase of $37 million.

Mr. BENNETT. From $225 million to $262 million, yes, sir, that is an increase of $37 million.

Mr. CANNON. That is a rather substantial increase.

Mr. BENNETT. Yes, sir, it is. We had, as you will remember, some rather high bids on a part of that work.

Mr. CANNON. And you had to accept it?

Mr. BENNETT. It was accepted and the work is now underway. The change in the benefit-cost ratio is the result of two things: (1) It is partly due to the increase in cost; and is also due to a shift from a 100-year period of analysis to a 50-year period of analysis, which reduces the benefit-cost ratio from 3.3 in 1958 to 1.38 now.

Mr. CANNON. What was the basis for reducing the payout from 100 to 50 years?

Mr. BENNETT. We felt in this particular instance we had as good an analysis, given the type of project we have, on a 50-year basis. Mr. CANNON. I do not quite understand what was to be gained by the reduction from a 100-year to a 50-year period. Presumably you are on a 100-year project?

Mr. BENNETT. Yes, sir.

Mr. CANNON. Wasn't that rather an arbitrary change?

Mr. BENNETT. That is correct, in showing it that way. Had we continued on the 100-year basis the ratio would have been 2.8.

TRINITY RIVER DIVISION SERVICE FACILITIES

Mr. CANNON. I notice a total under "Trinity River Division service facilities" of $3,906,430 is planned, including houses, sewer system, and so forth, of which $2,592,000 was obligated in 1957 and $1,115,000 is being committed this year.

At this point we will include in the record this tabulation of Trinity River division service facilities in fiscal year 1959 justifications. (The table follows:)
