Streamflow Characteristics

The U.S. Geological Survey (USGS) in cooperation with Colorado Springs Utilities selected 10 reaches or study areas along Fountain Creek between Colorado Springs and the confluence of Fountain Creek at the Arkansas River for annual bed and bank characterization and topographic surveys.

The peak-streamflow regional-regression equations (PSRREs) in the Plains hydrologic region in eastern Colorado have the largest uncertainty of any hydrologic region in Colorado. Reliable peak-streamflow information is critical for the proper design of stream-related infrastructure, such as bridges and dams, and flood-plain inundation maps. In an effort to provide more reliable peak-streamflow...

Reliable peak-streamflow data are critical to design transportation infrastructure, such as bridges, culverts, dams, and floodplain inundation maps. At gaged sites, where sufficient long-term streamflow data have been collected, statistics can be obtained from available publications, by an analysis of available data in the U.S. Geological Survey (USGS) National Water Information System (NWIS)...

StreamStats is a map based Web application that provides information that can be used by engineers, managers, and planners to make informed decisions on water-related activities. The map-based user interface can be used to delineate drainage areas, get basin characteristics and estimates of flow statistics. StreamStats allows for the analysis of upstream and downstream relations along streams. In...

Within the Southern Rockies Landscape Conservation Cooperative (SRLCC), streamflow information is needed for a wide variety of hydrologic conditions to understand streamflow in the context of ecological services, water availability and use, or water quality.

The U.S. Geological Survey, in cooperation with the Colorado Water Conservation Board, evaluated the predictive uncertainty of mean-monthly streamflow-regression equations representative of natural streamflow conditions in Colorado. This study evaluates the predictive uncertainty of mean-monthly streamflow-regression equations developed in a 2009 U.S. Geological Survey study using streamflow data...

Since the late 1800's, Colorado has experienced several periods of drought that have varied from about 2 to 12 years in duration. The Statewide drought from 1999 extended into 2002, a year characterized by lower than normal precipitation, snowpack accumulation, and streamflow. Statewide, mountain snowpack was about 53 percent of normal on April 1, 2002, the lowest since 1977 Accumulated...
