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...

USGS Earthmap Capacity Assessment Dataset
The U.S. Geological Survey provides a wide range of scientific information to an even wider group of stakeholders. Understanding what capacities are needed and if and or where these capacities exist across the USGS landscape is critical in moving science to the next level of use, implementation, and visualization.

Water-tables Elevations and Other Well Construction Data for 2008 and 2016 in Eastern Albuquerque, New Mexico
The purpose of this data release is to present well location and construction data for select wells representing the water table in eastern Albuquerque and the selected groundwater-level measurements at the wells from the winters of 2008 and 2016. Construction and groundwater-level measurement data include screening intervals at the water table, reference elevation, depth to water in feet and elev

Upper Rio Grande Basin water-resource status and trends: Focus area study review and synthesis
The Upper Rio Grande Basin (URGB) is a critical international water resource under pressure from a myriad of climatic, ecological, infrastructural, water-use, and legal constraints. The objective of this study is to provide a comprehensive assessment of the spatial distribution and temporal trends of selected water-budget components (snow processes, evapotranspiration (ET), streamflow processes, a

Water-quality trends in surface waters of the Jemez River and Middle Rio Grande Basin from Cochiti to Albuquerque, New Mexico, 2004–19
Municipal water supply for Albuquerque, New Mexico, is provided, in part, through diversion of surface water from the Rio Grande by way of the San Juan-Chama Drinking Water Project diversion structure. Changes in surface-water quality along the Rio Grande and its tributaries upstream from the San Juan-Chama Drinking Water Project diversion structure are not well characterized. This study describes

Water-table elevation maps for 2008 and 2016 and water-table elevation changes in the aquifer system underlying eastern Albuquerque, New Mexico
The addition of surface water from the San Juan-Chama Drinking Water Project to the Albuquerque water supply and the reduction in per capita water use has led to decreased groundwater withdrawals. This decrease in withdrawals has resulted in rising groundwater levels since 2008 in portions of the aquifer underlying Albuquerque.

Evaluation of modeled bacteria loads along an impaired stream reach receiving discharge from a municipal separate storm sewer system in Independence, Mo.
The Little Blue River in Jackson County, Missouri, was listed as impaired in 2012 due to Escherichia coli (E. coli) from urban runoff and storm sewers. A study was initiated to characterize E. coli concentrations and loads to aid in the development of a total maximum daily load implementation plan. Longitudinal sampling along the stream revealed spatial and temporal variability in E. coli loads. R
