Water Resource Assessment of the Rio San Jose Basin, West-Central New Mexico

Water resources in the Rio San Jose Basin are limited, and development for public supply, mining, agriculture, and commercial activities have the potential to affect the water availability and quality at a basin-wide scale. This study is designed to provide water-resource managers with better information to plan for potential effects of increased or shifting demands and changes of climatic...

Streamgaging: Silent Sentinels

Streamflow data are needed at many sites on a daily basis for forecasting flow extremes, making water-management decisions, assessing current water availability, managing water quality, and meeting legal requirements. These activities require streamflow information at a given location for a specified time. These needs generally are best satisfied by operating a station to produce a continuous...

URGWOM: Upper Rio Grande Water Operations Model

The Upper Rio Grande (URG) River Basin extends from the headwaters in Colorado to the USGS streamflow gage Rio Grande near Fort Quitman, Texas, and includes both native water and transmountain water from the Colorado River Basin. Because of surface-water allotment issues, input from various sources of water (native and transmountain), numerous reservoirs, and complex stream-aquifer relations,...

City of Santa Fe Groundwater Level Monitoring

In 1986, the USGS, in cooperation with the New Mexico Office of the State Engineer and the City of Santa Fe, drilled two well nests (Santa Fe nest 1 and Santa Fe nest 2) to monitor hydraulic head in the local aquifer systems. In 1987, three more well nests (Santa Fe nests 3, 4, and 5) were installed in the Buckman well field. In 1997, the City of Santa Fe partnered with the USGS to more...

Seismic analysis of the 2020 Magna, Utah, earthquake sequence: Evidence for a listric Wasatch fault

The 18 March 2020 Mw 5.7 Magna earthquake near Salt Lake City, Utah, offers a rare glimpse into the subsurface geometry of the Wasatch fault system—one of the world's longest active normal faults and a major source of seismic hazard in northern Utah. We analyze the Magna earthquake sequence and resolve oblique-normal slip on a shallow (30–35...

Integrated borehole, radar, and seismic velocity analysis reveals dynamic spatial variations within a firn aquifer in southeast Greenland

Perennial water storage in firn aquifers has been observed within the lower percolation zone of the southeast Greenland ice sheet. Spatially distributed seismic and radar observations, made ~50 km upstream of the Helheim Glacier terminus, reveal spatial variations of seismic velocity within a firn aquifer. From 1.65 to 1.8 km elevation,...
