SWOT - Surface Water and Ocean Topography
Satellite altimetry associated with the Surface Water and Ocean Topography (SWOT) mission offers a solution for measuring (1) river stage and slope, (2) water surface area including mean channel width and (3) derivatives such as river discharge. The measurements can be used to track changes in these variables and provide an accounting of the Earth's fresh-water bodies from space at the 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...
Numerical simulation of groundwater flow in the Lost Creek Designated Groundwater Basin, Weld and Adams Counties, Colorado
The Lost Creek Designated Ground Water Basin (LCDGWB) is an important alluvial aquifer for water supply in northeastern Colorado. Increased demand for withdrawals from the LCDGWB has led to a concern about the long-term sustainability of the basin’s ground-water resources.
A numerical ground-water flow model developed using an early version of MODFLOW exists for the LCDGWB. A review and...
Water budget and potential for underground storage in the Buena Vista-Salida Basin in Chaffee and parts of Fremont, Lake, and Saguache Counties, Colorado, 2009-2012
Population increases in the Upper Arkansas Headwaters Region, which includes Chaffee, Custer, Fremont, and Lake Counties, Colorado, are forecast to increase about 75 percent by 2030. An annual deficit gap between supply and demand of about 5,950 acre-feet is anticipated. Groundwater in the area is tributary to the Arkansas River but the effects of additional groundwater use are poorly...
Use of multivariate associations among species for detecting changes in native plains fish community structure in Colorado
The Colorado Parks and Wildlife (CPW) is responsible for monitoring the status of fishes in Colorado and currently seeks to establish a rigorous, efficient monitoring program for fishes that occur in stream habitats from the mountain-plains interface east to the Colorado state line. The primary goals of this program are to:
- monitor the status of species of concern designated ...
Bandelier National Monument Postwildfire Flood Support
In the summer of 2011, the Las Conchas Fire burned 156,593 acres in the Jemez Mountains in northern NM including the upper watersheds of Frijoles and Capulin Canyons in Bandelier National Monument. The drastic removal of vegetation in the upper watersheds of these popular tourist destinations left them susceptible to dangerous and record breaking floods. As long as the threat of large post-...
South Platte Alluvial Aquifer Water-Level Monitoring
Reports indicate that groundwater levels are rising in parts of the South Platte alluvial aquifer. The Colorado Division of Water Resources and the Colorado Water Conservation Board are establishing a groundwater-level monitoring network in the South Platte basin. The USGS National Water Quality Assessment Program (NAWQA) monitoring wells are uniquely located so as to be included in the...

Selenium Mobilization from Shales
Selenium (Se) and salinity (total dissolved solids) are water-quality concerns in much of the arid western US where agricultural and urban irrigation overlie Cretaceous-age shale. Leaching of Se and salinity from shale can degrade water quality and negatively affect aquatic biota in receiving water bodies. In the upper Colorado River Basin, programs since 1985 have worked to reduce Se and...
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...
Natural Resources Conservation Service Deep Percolation
The conversion of agricultural land to urban residential land is associated with rapid population growth in the Grand Valley of western Colorado. Information regarding the effects of this land-use conversion on deep percolation, irrigation-water application, and associated salt loading to the Colorado River is needed to support water-resource planning and conservation efforts.
Biosolids, soils, crops, ground water, and streambed sediments in the vicinity of a biosolids-application area near Deer Trail, Colorado
The Metro Wastewater Reclamation District (Metro District) applies biosolids throughout their properties (the MetroGro Farm) near Deer Trail, Colorado. These biosolids applications could affect the quality of water in alluvial and bedrock aquifers, streambed sediment, soil, dust, and crops.
Water quality can be directly affected through:
- Contaminated recharge water, or ...

Recent deaths of endangered boreal toads in Rocky Mountain National Park have been linked to a chytrid fungus and are the second such diagnosis in Colorado, according to scientists with the U.S. Geological Survey.
Dr. Mary Lou Zoback, a geophysicist with the U.S. Geological Survey and chief of that agency’s earthquake hazards program in Menlo Park, Calif., became the new president of the Geological Society of America (GSA), Wednesday, October 27, during the organization’s annual meeting at the Colorado Convention Center in Denver, Colo.
Recent deaths of endangered boreal toads in one of the largest remaining populations in the southern Rocky Mountains have been linked to a chytrid fungus identified last year as being responsible for amphibian die-offs in Central America and Australia, according to pathologists at the USGS National Wildlife Health Center in Madison, Wis.
Have you ever wondered about those rocks in your yard? Have you been curious about the dinosaurs that used to roam Colorado? Are you curious about how maps are made, what grizzly bears eat or how water is tested?
A new screening method, based on geology and climatology, has been shown to be a reliable means for predicting where lands in irrigated areas are susceptible to contamination from selenium, according to a report by the U.S. Geological Survey (USGS), in cooperation with the U.S. Fish and Wildlife Service, Bureau of Reclamation, and Bureau of Indian Affairs.
Retired U.S. Geological Survey geologist E. Bartlett "Bart" Ekren of Ft. Collins, Colo. was awarded the Dibblee Medal by the Dibblee Geological Foundation, on Friday, April 30 at the annual Pacific Section Meeting of the American Association of Petroleum Geologists for his innovative, high quality, and societally important contributions to understanding the geology of the Western United States.
