A review of current capabilities and science gaps in water supply data, modeling, and trends for water availability assessments in the Upper Colorado River Basin

The Colorado River is a critical water resource in the southwestern United States, supplying drinking water for 40 million people in the region and water for irrigation of 2.2 million hectares of land. Extended drought in the Upper Colorado River Basin (UCOL) and the prospect of a warmer climate in the future pose water availability challenges for those charged with managing the river. Limited wat

Characterization of the Sevier/Toroweap Fault Zone in Kane County, Utah, using controlled-source audio-frequency magnetotelluric (CSAMT) surveys

The Sevier/Toroweap Fault Zone is a major north-south-striking fault located in northern Arizona and southwestern Utah. In partnership with the National Park Service, the U.S. Geological Survey conducted two geophysical controlled-source audio-frequency magnetotelluric (CSAMT) surveys that transected the Sevier/Toroweap Fault Zone at Clay Flat, Utah, a potential pull-apart basin, west of a site of

Groundwater, surface-water, and water-chemistry data, Black Mesa area, northeastern Arizona—2018–2019

The Navajo (N) aquifer is an extensive aquifer and the primary source of groundwater in the 5,400-square-mile Black Mesa area in northeastern Arizona. Water availability is an important issue in the Black Mesa area because of the arid climate, past industrial water use, and continued water requirements for municipal use by a growing population. Precipitation in the area typically ranges from less

Southwest Gravity Program

The Southwest Gravity Program provides high-precision time-lapse gravity (repeat microgravity) data for hydrologic studies in the southwestern US. Recent projects include monitoring recharge underneath ephemeral-stream channels, monitoring aquifer-storage change in unconfined and compressible aquifers, measuring storage change at surface-spreading and injection-well artificial-recharge facilities...

Actionable Science

The Colorado River Basin Pilot Project is exploring new approaches for the USGS to answer complex earth systems questions identified in partnership with stakeholders, which cannot be answered through a single discipline approach. Science coproduction is a method where scientists, managers, policy makers, and other stakeholders first identify specific decisions to be informed by science, and then...

Integrated Science Approach

The USGS has a long history of delivering science and tools to help decision-makers manage and mitigate effects of drought. The timing is critical for the USGS to consolidate its diverse expertise into a single landscape-scale effort to rapidly provide integrated transdisciplinary, targeted data, tools, and models required by decision makers in the Basin. This initiative unifies USGS expertise...
