Cory A Williams
Cory A. Williams is a Supervisory Hydrologist with the USGS Colorado Water Science Center in Western Colorado. He leads a team of multidisciplinary scientists that study water-related issues throughout the Colorado Plateau.
Previously he served as the Sediment Specialist for the Colorado Water Science Center and as the Lead Hydrologist in Grand Junction, Colorado. He received a B.S. in Geology from Colorado Mesa University and an M.S. in Geosciences from Colorado State University, Fort Collins. Cory has lead numerous investigations evaluating trends in water quality and quantity throughout the Upper Colorado River Basin and is a Burn Area Emergency Response (BAER) Fluvial Geomorphologist. He has been with the USGS since 2001.

Using GIS and Multivariate Regressions to Model Salt and Selenium Loads in Regions of the Upper Colorado River Basin
Elevated loads of salt and selenium can impair the quality of water for both anthropogenic and natural uses. Understanding the environmental processes controlling how salt and selenium are introduced to streams is critical to managing and mitigating the effects of elevated loads. Dominant relations between salt and selenium loads and environmental characteristics can be established by using...

Evaluation of Streamflow Gain-Loss Characteristics of Hubbard Creek, in the Vicinity of a Mine-Permit Area, Delta County, Colorado, 2007
In 2007, the U.S. Geological Survey, in cooperation with Bowie Mining Company, initiated a study to characterize the streamflow and streamflow gain-loss in a reach of Hubbard Creek in Delta County, Colorado, in the vicinity of a mine-permit area planned for future coal mining. Premining streamflow characteristics and streamflow gain-loss variation were determined so that pre- and postmining gain-l

Using the tracer-dilution discharge method to develop streamflow records for ice-affected streams in Colorado
Accurate ice-affected streamflow records are difficult to obtain for several reasons, which makes the management of instream-flow water rights in the wintertime a challenging endeavor. This report documents a method to improve ice-affected streamflow records for two gaging stations in Colorado. In January and February 2002, the U.S. Geological Survey, in cooperation with the Colorado Water Conserv

Using tracers to evaluate streamflow gain-loss characteristics of Terror Creek, in the vicinity of a mine-permit area, Delta County, Colorado, water year 2003
In 2003, the U.S. Geological Survey, in cooperation with Delta County, initiated a study to characterize streamflow gainloss in a reach of Terror Creek, in the vicinity of a mine-permit area planned for future coal mining. This report describes the methods of the study and includes results from a comparison of two sets of streamflow measurements using tracer techniques following the constant-rate

Evaluation of Streamflow Losses Along the Gunnison River from Whitewater Downstream to the Redlands Canal Diversion Dam, near Grand Junction, Colorado, Water Years 1995-2003
In 2003, the U.S. Geological Survey, in cooperation with the Colorado Water Conservation Board, Upper Colorado River Endangered Fish Recovery Program, Colorado River Water Conservation District, Colorado Division of Water Resources, and Bureau of Reclamation, initiated a study to characterize streamflow losses along a reach of the Gunnison River from the town of Whitewater downstream to the Redlan
