USGS Scientists Study Effects of Gold King Mine Release

Photograph showing natural iron-rich acidic spring flowing into Cement Creek near Silverton, Colorado.On August 5, while investigating the Gold King Mine in southwestern Colorado, the U.S Environmental Protection Agency accidentally triggered the release of approximately three million gallons of acidic, metal-rich mine wastewater from the Gold King Mine into Cement Creek, a tributary of the Animas River. The Animas River flows south into the San Juan River, which is a tributary to the Colorado River.

Snowpack Sublimation: Measurements and Modeling in the Colorado River Basin

Lochvale Blowing Snow

The U.S. Geological Survey (USGS) is conducting a study of snowpack sublimation in the Colorado River Basin as part of the USGS National Water Census program, in cooperation with the Colorado Water Conservation Board. The primary goal is to develop snowpack sublimation estimates for the Colorado River Basin using ground-based measurements and moderate-resolution and high-resolution gridded models. The results support hydrologic modeling studies, water-availability studies, and water-use assessments.

Water-Quality Summaries for Several Major River Basins in Colorado

Summaries of water-quality monitoring data are now available for several major river basins in Colorado. For each basin, current data from a network of sites are compared to previously collected data and instream standards. Lowess curves are provided on plots for selected constituents where a sufficient period of record and limited censored data are available.

Colorado Water-Quality Data Repository (CWQDR)

An internet-based data management system that integrates ambient water-quality data from a variety of sources including government agencies, stakeholder groups, and private entities.
