Topographic Survey and Streambed-Sediment Data of Fountain Creek between Colorado Springs and the Confluence of Fountain Creek at the Arkansas River, Colorado, 2018

In 2012, the U.S. Geological Survey (USGS) in cooperation with Colorado Springs Utilities selected 10 study reaches along Fountain Creek between Colorado Springs, Colorado and the confluence of Fountain Creek with the Arkansas River for annual bed and bank characterization and topographic surveys. The 10 study reaches are approximately 5 to 20 bank-full channel widths in length. Data were collected in 2018 that are similar in method and scope as data collected from 2012 to 2017.Topographic survey points were collected using real-time kinematic Global Navigation Satellite Systems (RTK-GNSS). Pebble-count data were collected at all 10 study reaches and included 4 measurements of grain size at each of 25 equally spaced stations along 4 separate transects across the active channel of each study reach. If 10 percent or more of the samples measured along the pebble-count transect were fine sand or silt (less than 2 millimeters), a streambed-sediment sample was collected for sieve-size analysis at the USGS Iowa Water Science Center Sediment Lab In Iowa City, Iowa.
