MRG Regional Water Plan Update - Additional Studies

Relevant Studies, Analyses, and Reports - The Middle Rio Grande Region (Sandoval, Bernalillo and Valencia Counties) and Basin (Cochiti Reservoir to Elephant Butte Reservoir) have been the beneficiaries of lots of applicable studies, analyses, and reports which should not be ignored.  Links to selected documents appear below.

Middle Rio Grande Water Supply Study (MRGWSS) - 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.

These products provide an up-to-date integration of past and on-going technical studies that can be used in the regional water planning process.  This study builds on the previous Water Supply Study, providing planners with improved analysis of water supply conditions and Compact compliance under both current and potential drought scenarios, and provides a clear assessment of the potential impacts of the Middle Rio Grande, Socorro-Sierra, and Jemez y Sangre planning region water planning alternatives on Compact deliveries to Elephant Butte Reservoir.
