Andre Ritchie

Modeling and GIS Specialist, New Mexico Water Science Center

Andre Ritchie is a hydrologist in the hydrogeology and geochemistry program area at the New Mexico Water Science Center. Andre received a M.S. degree in Hydrology from the New Mexico Institute of Mining and Technology, and a B.S. degree in Geology from the University of North Carolina Wilmington. Since joining the USGS in 2015, Andre's work has been focused on using hydrogeology and integrated hydrologic modeling to answer questions relating to surface-water/groundwater interaction, farm-scale agricultural conjunctive use, and management of surface-water and groundwater resources.

Rio Grande Transboundary Integrated Hydrologic Model: Modeling Conjunctive Use to Support Resource Management

The Palomas, Mesilla, and Conejos-Médanos Basins in New Mexico, Texas, and northern Mexico compose a geologically and hydrologically complex region. The conjunctive use of surface water and groundwater takes place under a myriad of legal and operational constraints, including the Rio Grande Compact, an international treaty, and the U.S. Bureau of Reclamation’s Rio Grande Project. New demands are...

Potentiometric Surfaces and Groundwater-Level Changes

In the past, groundwater pumped from the Santa Fe Group aquifer system was the principal source of water for the Albuquerque metropolitan area of central New Mexico. The large quantity of groundwater pumping relative to recharge resulted in substantial drawdown in the aquifer system. In 2008 the Albuquerque Bernalillo County Water Utility Authority began diverting water from the San Juan-Chama...

Aquifer Compaction, Recovery, and Land-surface Elevation Change in the Albuquerque Basin

In many groundwater basins in the arid to semiarid western United States, permanent regional-scale land-surface elevation change has resulted from substantial drawdown of groundwater levels. By the end of 2008, groundwater drawdown from municipal pumping in the Albuquerque area had reached as much as 120 feet below predevelopment (~1950s) water levels. In 2014 the USGS, in cooperation with the...

Mesilla / Conejos-Médanos Basin: U.S.-Mexico transboundary water resources and research needs

Synthesizing binational data to characterize shared water resources is critical to informing binational management. This work uses binational hydrogeology and water resource data in the Mesilla/Conejos-Médanos Basin (Basin) to describe the hydrologic conceptual model and identify potential research that could help inform sustainable management. The Basin aquifer is primarily composed of continuous

Water-level data for the Albuquerque Basin and adjacent areas, central New Mexico, period of record through September 30, 2018

The Albuquerque Basin, located in central New Mexico, is about 100 miles long and 25–40 miles wide. The basin is hydrologically defined as the extent of consolidated and unconsolidated deposits of Tertiary and Quaternary age that encompasses the structural Rio Grande Rift between San Acacia to the south and Cochiti Lake to the north. A 20-percent population increase in the basin from 1990 to 2000
