Cory A Williams
Cory A. Williams is a Supervisory Hydrologist with the USGS Colorado Water Science Center in Western Colorado. His leadership roles include Upper Colorado Integrated Water Science (IWS) Basin Coordinator, Federal representative to the Colorado River Salinity Control Forum, and Western Colorado Hydrologic Investigations Section Supervisor.
He leads a team of multidisciplinary scientists that work with local and federal partners to study water-related issues throughout the Colorado Plateau. Cory has led 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. Cory has proudly studied the Upper Colorado River with USGS since 2001. He received his B.S. in Geology from Colorado Mesa University and his M.S. in Geoscience from Colorado State University, Fort Collins.

Integrated Water Science Basins: Upper Colorado River
The Upper Colorado River Basin (UCRB) provides drinking water for 40 million people in the United States and Mexico. USGS research in the UCRB examines the key potential factors affecting water supply in the upper portion of the basin—snow processes and water storage, wildfire and basin hydrology, and salinity concentrations and water quality.
Sediment Acoustics
The U.S. Geological Survey recognizes the need to provide sediment acoustic training and to develop standardized techniques and practices.
Fountain Creek Watershed Flood and Sediment Transport Study
The Fountain Creek watershed, Colorado, is characterized by steep channel slopes and varied land use. Spatially distributed precipitation events result in varying rates of direct runoff. These dynamics contribute to large streamflows and sediment transport, which has caused periodic flooding, and sediment aggradation and deposition in Fountain Creek and its tributary streams. The U.S. Geological...
Reconfigured Channel Monitoring and Assessment Program (RCMAP)
Channel reconfiguration to mitigate a variety of riverine problems has become an important issue in the Western United States. Reasons cited for channel reconfiguration include restoration to more natural or historical conditions, improved water conveyance in flood-prone areas, mitigation of unstable streambed and streambanks, increased sediment transport, and enhancement of riparian habitat or...
RCMAP - Muddy Creek below Wolford Mountain Reservoir near Kremmling, Colorado
The U.S. Geological Survey was engaged in a program to monitor and assess the long-term geomorphic behavior of selected river and stream reaches that previously had undergone some physical modification. These modifications included natural channel adjustments to floods as well as intentional channel reconfigurations to alter the function or appearance of a river reach.
RCMAP - Lake Fork of the Gunnison near Lake City, Colorado
The U.S. Geological Survey was engaged in a program to monitor and assess the long-term geomorphic behavior of selected river and stream reaches that previously had undergone some physical modification. These modifications included natural channel adjustments to floods as well as intentional channel reconfigurations to alter the function or appearance of a river reach.
RCMAP - North Fork Gunnison River at Hotchkiss, Colorado
The U.S. Geological Survey was engaged in a program to monitor and assess the long-term geomorphic behavior of selected river and stream reaches that previously had undergone some physical modification. These modifications included natural channel adjustments to floods as well as intentional channel reconfigurations to alter the function or appearance of a river reach.
RCMAP - Gunnison River at the Hartland Dam near Delta, Colorado
The U.S. Geological Survey was engaged in a program to monitor and assess the long-term geomorphic behavior of selected river and stream reaches that previously had undergone some physical modification. These modifications included natural channel adjustments to floods as well as intentional channel reconfigurations to alter the function or appearance of a river reach.
Lower Yampa Streamflow and Sediment Modeling
Water from the Yampa River basin continues to be sought for a number of municipal, industrial, and energy uses. Water development in the Yampa River basin will alter the streamflow regime and, consequently, will lead to changes in the transport and storage of suspended and bedload sediment. Changes in the Yampa River sediment budget could lead to changes in channel geometry, riparian vegetation...
Gunnison and Green River Basin Sediment Monitoring and Evaluation Program
Underlying geomorphic processes relevant to the formation and maintenance of backwater habitats are relatively poorly understood, particularly the effects of peak-flow magnitude and duration; sediment deposition and erosion; base-flow magnitude and variability; and antecedent conditions on habitat availability and conditions. Knowledge of sediment dynamics in important river reaches is critical to...
RCMAP - Gunnison River at Spann Diversion at Gunnison, Colorado
The U.S. Geological Survey was engaged in a program to monitor and assess the long-term geomorphic behavior of selected river and stream reaches that previously had undergone some physical modification. These modifications included natural channel adjustments to floods as well as intentional channel reconfigurations to alter the function or appearance of a river reach.
RCMAP - Uncompahgre River at Ridgway, Colorado
The U.S. Geological Survey was engaged in a program to monitor and assess the long-term geomorphic behavior of selected river and stream reaches that previously had undergone some physical modification. These modifications included natural channel adjustments to floods as well as intentional channel reconfigurations to alter the function or appearance of a river reach.
