Tectonically driven integration of the 4.8 Ma Colorado River USA tracked with detrital sanidine and fish genetics Tectonically driven integration of the 4.8 Ma Colorado River USA tracked with detrital sanidine and fish genetics
The development of the continental-scale Colorado River system, western USA, from 8 to 4.8 Ma, is revealed using 60-40 Ma detrital sanidine tracer grains and fish phylogeny. Here we show that precursor paleoriver segments became integrated north to south as traced by 60-40 Ma sand grains that were derived from the north and sequentially appeared in the 25-8 Ma Browns Park Formation of...
Determination of baseline water-quality conditions using continuous specific conductance and discrete measurements of total dissolved solids and selected major ions, Arkansas River Basin, Colorado Determination of baseline water-quality conditions using continuous specific conductance and discrete measurements of total dissolved solids and selected major ions, Arkansas River Basin, Colorado
From 2022 through 2024, the U.S. Geological Survey (USGS) in cooperation with the Regional Resources Planning Group (Southeastern Colorado Water Conservancy District, Colorado Springs Utilities, Pueblo Water, Lower Arkansas Valley Water Conservancy District, Aurora Water, and Upper Arkansas Water Conservancy District) established a basinwide water-quality monitoring network in the...
Mercury biomagnification across food webs with varying non-native fish presence: Implications for native fish conservation in the upper Colorado River Basin Mercury biomagnification across food webs with varying non-native fish presence: Implications for native fish conservation in the upper Colorado River Basin
Environmental contaminants and non-native species introductions negatively affect aquatic ecosystem conservation. Mercury (Hg) accumulates within food webs where it can biomagnify to toxic concentrations, which can be affected by altered trophic relationships from non-native species. This study examined Hg concentrations (n samples = 655) and stable carbon and nitrogen isotope (n = 746)

2026 Venezuela Sequence Earthquake-Triggered Landslide Hazards
On Wednesday, June 24th, 2026, a pair of earthquakes of Magnitude 7.2 and Magnitude 7.5 occurred in northern Venezuela, west of Caracas. The U.S. Geological Survey (USGS) Ground Failure product estimated that landslides triggered by this earthquake would likely be significant in number and/or spatial extent. This landslide event page serves to communicate timely science information to our partners...
Modernized Breeding Bird Survey Portal
The North American Breeding Bird Survey (BBS) Portal is a modern information system that enables volunteer observers and regional coordinators to manage survey routes, enter field data, and coordinate route assignments online. The portal replaces legacy paper-based and outdated digital workflows with a streamlined interface built for the BBS community. Observers can view their assigned routes...
Water Quality
The USGS, in partnership with multiple other groups, is learning about water-quality conditions across time and space in terminal lakes across the Great Basin. This effort is part of the Saline Lake Ecosystems Integrated Water Availability Assessment.
