The gravity system of water-works, constructed during the years 1893 and 1894 by the Water Committee of the City of Portland, Oregon, included a series of four reservoirs for supplying the different districts of the city. Reservoir No. 1, with a capacity of 12 000 000 galls., and No. 2, with a capacity of 20 500 000 galls., supply the East Side District; and Reservoir No. 3, with a capacity of 16 400 000 galls., and No. 4, with a capacity of 17 700 000 galls., supply the West Side District. Two of these reservoirs, Nos. 3 and 4, on the West Side, were built in a narrow ravine occupying a portion of the City Park, about two miles west of the business center of the city. The lower reservoir has an elevation of 220 ft. and the higher one 290 ft. above mean low-water level of the Willamette River. These two reservoirs were formed by dressing down the banks of the ravine in which they are located; and, since their completion, a serious derangement of the western slopes of both reservoirs bas taken place, owing to a movement of the adjacent hillside.
