Washoe, a N. W. county of Nevada, bordering on California; area, 2,316 sq. in.; pop. in 1870, 3,091, of whom 221 were Chinese; in 1875, 3,953, of whom 267 were Chinese. The N. part is mostly a desert. Pyramid lake in the S. part, 33 m. long by 14 m. wide, receives the waters of Truckee river from the south, and there are several other lakes. The valleys of Washoe lake, Steamboat springs, and Truckee river form a single tract of arable and cultivated land, 30 m. long by from 3 to 6 m. wide. The mountains W. of this tract and about the head waters of the Truckee contain pine forests. N. of the river copper, gold, and silver are found, and W. of Washoe City are deposits of lead ore; but the mineral resources are limited and undeveloped. Steamboat springs, about 4 m. N. of Washoe City, are so called, from the clouds of steam that constantly rise from them. The Central Pacific railroad passes along the S. border. The chief productions in 1870 were 2,874 bushels of wheat, 8,825 of oats, 17,250 of barley, 17,570 of potatoes, and 5,399 tons of hay.
