Municipal, industrial, and irrigation water use in Washington, 1965

Estimates of ground-water pumpage from the Yakima River Basin aquifer system, Washington, 1960-2000

“…Kinnison and Sceva (1963) estimated about 24,000 acre-ft of irrigation pumpage (about 50 percent of the annual appropriated quantity) for 1953 compared to this study's estimate of about 36,000 acre-ft (about 77 percent of the annual appropriated quantity). Laird and Walters (1967) estimated about 79,000 acre-ft of irrigation pumpage (about 97 percent of the annual appropriated quantity) for 1965, compared to this study's estimate of about 56,000 acre-ft (about 73 percent of the appropriated quantity). Last, Parker (1971) estimated irrigation pumpage at about 81,000 acre-ft for 1970 compared to this study's estimate of about 75,000 acre-ft; both estimates have a similar percentage of the appropriated quantity (73 and 78 percent, respectively).…”

“…Industrial pumpage was estimated at 14,600 acre-ft (4.8 Bgal), municipal supply at 7,800 acre-ft (2.5 Bgal), and domestic pumpage at 5,365 acre-ft (1.7 Bgal). Laird and Walters (1967) estimated that total pumpage in 1965 was about 138,800 acre-ft (45.2 Bgal) for the threecounty area with irrigation accounting for 57 percent (79,200 acre-ft or 25.8 Bgal) of the total. Municipal pumpage was about 46,000 acre-ft (15 Bgal) and industrial was 13,470 acre-ft (4.4 Bgal).…”
