AGRICULTURAL CONDITIONS. Irrigable area: 243,000 acres. Ownership of irrigable lands: Public, 67,711 acres; state and private, 175,289 acres. Lands irrigated, season of 1909: Public, 15,000 acres; private, 97,000 acres. Character of soil of irrigable area: Light sandy loam. Duty of water: 24 acre-feet per acre per annum at the farm. Principal products: Alfalfa, sugar beets, apples, prunes, and small fruits. Principal markets: Payette, Nampa, Boise, Meridian, and Caldwell, Idaho; Portland, Oreg.; eastern cities. History: Reconnaissance made in 1902-1904; project approved by Secretary of the Interior, March 25, 1905; construction begun March 16, 1906. The degree of completion at the end of 1910 for the south side unit will be about 76 per cent, exclusive of Boise River storage, and about 44 per cent, inclusive of this storage. Expenditures: The above-noted expenditure, $3,742,000, enables the completion at the end of 1910 of the Boise River diversion dam, and the main south side canal from Boise River to Deerflat reservoir, which serves also about 108,400 acres of land above Deerflat reservoir. Excavation for the entire length of the canal is finished for a base width of 40 feet, and for a base width of 70 feet for considerable portion. It is also lined with concrete for a length of about 20,000 feet. The distribution system will have been completed for about 100,000 acres of land; also reconnaissance surveys made for reservoirs on Boise River and borings for one site. The completion of this unit of the project for the new lands involved contemplates work costing about $4,900,000, as follows: Boise River storage for new lands; completing main south side canal and headworks; completing Deerflat reservoir; completing lateral system; providing drainage system, etc. This estimate is roughly approximate, since the figures are based on preliminary surveys only, no testing for foundation having yet been made. The lands to be irrigated from the works covered by the expenditure are as follows: Under Deerflat reservoir, 55,600 acres; under main south side canal, 108,400 acres; total, 164,000 acres. The above acreage does not include the following lands, which it is roughly estimated can be furnished with storage from Deerflat reservoir by the expenditure of $200,000: Under New York canal, 18,000 acres; under Ridenbaugh canal, 25,000 acres; under Pioneer Irrigation District, 36,000 acres; total, 79,000 acres. This land is largely signed up to the water users' association for storage water. KANSAS GARDEN CITY PROJECT. LOCATION AND CLIMATIC CONDITIONS. Counties: Finney and Kearny.
