Irrigated AgricultureReed Burkholder - March 24, 1997
Irrigated agriculture using water from the 4 lower Snake River dams amounts to 35,000 acres, all near Ice Harbor reservoir. Water is pumped from the top of the full reservoir to cropland 20-560 vertical feet above the surface of the reservoir.
Washington's total cropland is about 6,500,000 acres. The 35,000 irrigated acres which use Ice Harbor water amount to roughly 1/2 of 1% of Washington's total cropland.
