EFFECTS OF ENERGY DEVELOPMENT IN THE UPPER COLORADO BASIN ON IRRIGATED AGRICULTURE AND SALINITY

A mathematical programming model is formulated to determine the salinity impacts of energy development in the Upper Colorado River Basin. Using this model, the costs and benefits to Upper and Lower Basins in complying with the 1974 EPA regulations on numerical salinity standards are examined. Optimal water quality levels consistent with economic criteria are established for projected energy growth in the basin. The efficiency costs and equity implications of the salinity regulations are analyzed.
