Agricultural water use in the binational Lower Colorado River Basin is about ninety percent of all the beneficial use. Fast growing border cities of Baja California and conservation uses will increase their water allocations in the near future. The CALVIN economic-engineering model was used to evaluate the benefits and costs of a variety of water management strategies in the Lower Colorado River Delta in Mexico. Results show that at 2025 water demand conditions, agriculture seems to be the most suitable donor of water to other sectors. Wastewater reuse for irrigation and/or conservation purposes may reduce dependence on agricultural water imports to fulfill future demands.
