Water Optimization in Utah

A layered approach combining ground-based and remote sensing methods is recommended to accurately measure and account for agricultural water depletion in Utah, enhancing water rights administration and optimizing water use.

The Colorado River sustains millions through agriculture, tribal rights, and state allocations under layered compacts and treaties. Growing drought and climate pressures are driving new rules for its future use.

Cost-effective irrigation technologies and practices like deficit irrigation and conservation tillage can optimize agricultural water use in Utah while maintaining crop productivity.

The Utah Agricultural Water Optimization Task Force is conducting trials to evaluate combinations of irrigation technologies and crop management practices that reduce water use by up to 25% while maintaining or improving agricultural yields in Utah.

Drip irrigation in Utah significantly reduces water diversion by over 50% and consumptive use by about 20% compared to surface irrigation, while maintaining high onion yields, though it requires proper design, management, and potentially infrastructure im...
