Middle Rio Grande Water Supply Study

The Middle Rio Grande Water Supply Study was initiated in June 1999 as a joint project of the New Mexico Interstate Stream Commission and the U.S. Army Corps of Engineers. The study was conducted as the first step of a broad regional water planning process, addressing the question, "What is the water supply for the region?" To answer this question, the study quantified the conjunctive groundwater-surface water supply for the region from Cochiti Dam to Elephant Butte Reservoir, considering the constraints of the Rio Grande Compact. An Executive Steering Committee comprised of water resource engineers and scientists, and major stakeholders in the study area provided technical advice and guidance during the project.

Phase 1 of the study identified hydrologic data, reviewed key water budget studies, and developed a Work Plan to quantify the conjunctive use water supply in the Middle Rio Grande region. Phase 2 implemented the Work Plan and culminated in August 2000 with the release of a comprehensive report, available below. Phase 3 of the study will further refine the characterization of the components and processes of the hydrologic budget of the study region and the probabilistic model developed during Phase 2. Important details on Phase 3 of the study will be posted on this page as the study progresses.
