Irrigated agriculture and electrical energy supply in the Pacific Northwest are intricately bound by mutual dependence on Columbia River Basin water. Diversion and instream demands on the water have intensified through recent development in the region. Water conservation opportunities exist in present irrigation that could supplement regional firm hydroelectricity. A two-level mathematical programming model is developed to evaluate irrigator production and regional price responses to water and electricity conservation policies. Stage one emphasizes decision criteria at producer level - irrigable land, water, electricity and labor demand, and water response yields on major crops. Irrigators choose cropping and irrigation mixes and rates at expected commodity prices under resource constraints consistent with regional policy. Stage two employs production and resource use solutions from stage one in a regional allocation and price equilibrium-seeking program. Alfalfa, apple, and potato prices are determined endogenously, and a decomposition-type linkage reiterates production area response to regional equilibrium prices. Baseline irrigated acreage, water electricity, production, and crop prices are estimated for 1982. Water pricing policies reflecting the opportunity value of Columbia River water for hydrogeneration indicate increasing net social benefits, net farm returns, and hydropower potential accruing from conservation in irrigation.
