Title Slide for Lower Colorado River Basin Panel Discussion for USGS Virtual Open House meeting to discuss drought issues with Native American Tribal Members. Held online via Microsoft Teams on November 29, 2024.

March-August daily average streamflow for the last 30 years (1991-2022) (dark gray lines) compared to 2023, showing the periods where 2023 streamflow was above (blue) and below (orange) the historical average. Individual years of the relevant historical streamflow period are shown in light gray.

Researchers inject fluorescein dye into Lake Fork Creek, Colorado, in August 2023. This study aims to trace water flow from the historic Sugarloaf mining district into the creek.

Pit dug for collection of geologic data and observations, such as geochronology samples to determine the age of faulted surfaces and documentation and dating of faulted recent sediments of the Puya Fault in northern New Mexico, 4/25/2023.

Map showing distribution of average annualized earthquake loss by region. The high concentration of loss in California and the West Coast is consistent with that region’s high seismic hazard, significant population, and building exposure.

Although most economic loss is concentrated along the west coast, the distribution of relative earthquake risk, as measured by the Annualized Earthquake Loss Ratio (AELR), is spread throughout the country and it reinforces the fact that earthquakes are a national problem.

The large HTHH volcanic explosion created fast low-frequency pressure waves that penetrated about 3.1 miles/5 kilometers into the shallow crust (shown in yellow). Wind and small explosions (shown in blue) create shorter pressure waves that only penetrate down about 328 feet/100 meters.

The waveforms of the ground motion recording and the pressure sensor recording from a station with both types of instruments (see second image above) match up, indicating that the pressure waves are causing the ground (crust) to deflect.

This research effort is an interagency partnership between U.S. Geological Survey and U.S. Fish and Wildlife Service to model the social-ecological system that encompasses chronic wasting disease management in the United States.
