For descripon of the Columbia River see page 1605. Existing project. This project provides for a dam, power plant, and lock, for power and navigation. The spillway dam extends across the main river channel from the Washington shore to Bradford Island, which divides the river at this point. The overflow crest at 24 feet above mean sea level is surmounted by 18 vertical-lift steel gates placed between piers which extend to elevation 99 feet where a service roadway permits the operation of two 350-ton gantry cranes for regulating the gates. The powerhouse extending across Bradford Slough to the Oregon shore has an installation of 10 units, consisting of 2 units of 43,200 kilowatts each and 8 units of 54,000 kilowatts each totaling 518,400 kilowatts. The ordinary and extreme fluctuations of the river at the lower lock gate are about 21 and 47 feet, respectively. The project includes fish ladders and lccks to serve both the main channel and the Bradford Slough channel. The lock and powerhouse are founded on andesite, and the main dam rests upon solidified sedimentary rock of volcanic origin. The pool created by the spillway dam provides a navigable channel, with depths of 30 feet and over, between Bonneville and Big Eddy, a distance of 47 miles. The principal data concerning the ship lock and spillway dam are shown in the following table: The estimated cost of the dam, navigation lock, 10-power unit generating installation, fishways, and attendant buildings and grounds, revised in 1945, is $81,386,000 of which $6.209,500 is for navigation facilities, $36,588,940 is for power facilities, and $38.587,560 is for joint facilities, consisting of dam, fishways, buildings and grounds, and the head-wall section of power units No. 0-6, cost of which ($2,016,817) is allocated to dam and reser voir facilities. The estimated annual cost of operation and maintenance is $650,000, $72,400 of which is for navigation, $356,000 is for power, and $221,600 for joint facilities. The existing project was authorized by the following river and harbor acts: Terminal facilities.—At the Port of The Dalles (mile 44 above Bonneville) there is a municipal wharf 125 by 1,100 feet for use of both ocean vessels and river boats. There are two one-story timber and corrugated-iron warehouses, each 94 by 461 feet, on this wharf. Rail connection to the municipal wharf is now under construction. There is also a municipal oil terminal consisting of a concrete and timber wharf, 27 by 193 feet, located about a mile below the main wharf. There are private storage tanks with a total capacity of 2,300,000 gallons located near this terminal for handling petroleum products from ocean vessels and river boats. Storage tanks have rail and truck connections. A private elevator with a capacity of 40,000 bushels and a public elevator of 500,000 bushels capacity for handling bulk grain to ocean or river craft are also located at The Dalles. The public elevator has rail and truck connections. There is a privately owned rail connection about three-fourths mile below the municipal wharf where certain types of cargo may be handled between railroad cars and river boats or barges, by means of a derrick of 22-ton capacity. The facilities are considered adequate for present commerce. Operations and results during the fiscal year-New work.Work was resumed on the spare 60,000 kilovolt-ampere, 13.8 kilovolt-115 kilovolt transformer remaining under contract. Since the beginning of September 1943, the elevation of the Bonneville pool has been raised to elevation 78.0 from a normal pool level of elevation 72.0 during the low-water season, at all times that such increase would make more power available for war work. This change has made approximately 9 percent more power available during the low-water periods, and a large percentage of this power has been sold. Operating and care.-The existing project with 10-power units was operated throughout the fiscal year, with only minor interruptions, except for routine maintenance as scheduled. The total cost of work done during the year amounted to $717,059.88 of which $107,613.58 was for new work, including $31, 886.90 for features other than power installation, $75,726.68 for power features, and $609,446.30 for maintenance (operation and care), including $359,572.98 for power facilities. Total expenditures were $889,961.52, of which $632,935.68 was for features of work other than power and $257,025.84 for power features. Condition at the end of the fiscal year.-The existing project is 98 percent complete. Power facilities.-The powerhouse with 10-power units and a station service unit is completed, except for such miscellaneous work as was postponed until after the war, and is in operation. The rated capacity of the plant is 518,400 kilowatts. Navigation facilities.-The navigation lock is completed and has been open to river traffic since January 1938. Dam and reservoir.-The spillway dam is completed, except for minor work, and is in operation. All work in connection with the reservoir is completed, except for the consummation of some settlements, land acquisition, and protective construction. Fishways. All fish ladders, collecting systems, and locks are completed and in operation. The work remaining to be done to complete the project consists of completing miscellaneous items of work in the powerhouse and on the other project features. The total costs and expenditures of work done under emergency funds to the end of the fiscal year amounted to $32,440,700, all for new work. The total costs of the work done under regular funds to the end of the fiscal year amounted to $50,753,273.40, of which $47,736,442.63 was for new work and $3,016,830.77 for maintenance (operating and care); total expenditures were $50,700,423.78. The total costs, all funds, to the end of the fiscal year amounted to $83,216,885.32, of which $80,177,142.63 ($25,382,899.78 for power facilities and $54,794,242.85 for other features of work) was for new work, and $3,039,742.69 for maintenance (operating and care), including $359,572.98 for operation and care of power facilities. Total expenditures were $83,141,123.78, of which $25.379,516.82 was for power installation only, units 3-10, and $57.761,606.96 for installation of power units 0-2, construction of all facilities other than power, operation and maintenance.
