Gravity meter sensitivity to mass change in the subsurface
As generalized in this image, a gravity measurement is sensitive to a cone-shaped region of the subsurface—as depth increases, the sensitivity to individual water molecules decreases, but the region of sensitivity expands.

Lees Ferry - 100 Years of Streamflow Monitoring
On October 1, 2021, the U.S. Geological Survey Colorado River streamflow gaging site (USGS 09380000) at Lees Ferry will mark its 100-year anniversary of recording continuous streamflow data.

Colorado River: Spring Disturbance Flow
For five days in March of 2021, the Glen Canyon Dam released a historically low flow of 4,000 cubic feet per second into the Colorado River.

A partnership to protect critical infrastructure
This video is an introduction to the partnership between the USGS Arizona Water Science Center and the Arizona Department of Transportation, or ADOT, as it is referred to throughout the video. These two agencies are working together, using cutting edge technology and methods, to understand how flood flows interact with and impact critical infrastructure.

A USGS guide for finding and interpreting high-water marks (AD)
High-water marks provide valuable data for understanding recent and historical flood events. The proper collection and recording of high-water mark data from perishable and preserved evidence informs flood assessments, research, and water resource management.
