Title: Elevation and Elevation-Change Maps of Fountain Creek, Southeastern Colorado, 2015–20 Prepared in cooperation with Colorado Springs Utilities By Laura A. Hempel, Andrea L. Creighton, and Andrew R. Bock 2021 U.S. Geological Survey Scientific Investigations Map 3481 Data release available at https://doi.org/10.5066/P98J7DRO ---------------------------------------------------------------------------- ABSTRACT: The U.S. Geological Survey, in cooperation with Colorado Springs Utilities, has collected topographic data annually since 2012 at 10 study areas along Fountain Creek, southeastern Colorado. The 10 study areas were located between Colorado Springs and the terminus of Fountain Creek at the Arkansas River in Pueblo. The purpose of this report is to present elevation maps based on topographic surveys collected in 2020 and to present maps of elevation change that occurred between 2015 and 2020 at all 10 study areas. Elevation and elevation-change maps were developed in Global Mapper, R, and ArcGIS from topographic surveys collected at each study area during the winters of 2015 and 2020. Topographic surveys in 2015 were completed using real-time kinematic Global Navigation Satellite Systems. Topographic surveys in 2020 were completed using both real-time kinematic Global Navigation Satellite Systems and light detection and ranging. Elevation-change maps were created using propagated uncertainties associated with the 95-percent confidence limit. Study areas along Fountain Creek underwent a range of geomorphic responses between 2015 and 2020 that were often related to the dominant channel planform pattern of the study area. The results of this ongoing monitoring effort can be used to assess long-term changes in land-surface elevation and to advance understanding of the geomorphic response to possible changes in flow conditions on Fountain Creek. ---------------------------------------------------------------------------- DISCLAIMERS: Although these data have been processed successfully on a computer system at the U.S. Geological Survey, no warranty, expressed or implied is made regarding the display or utility of the data on any other system, or for general or scientific purposes, nor shall the act of distribution constitute such warranty.

These Portable Document Format (PDF) files can be downloaded, from which paper copies may be printed. Acrobat software runs on a variety of systems, and is available for download free of charge from Adobe at http://www.adobe.com. How to View Data for Features in the Interactive PDF File: To view the different data layers, the maps must be downloaded and opened with a PDF viewer such as Adobe Acrobat Reader; there are known incompatabilities with the interactive functions and web browsers. When the map sheet is open in Adobe Acrobat Reader, three clickable buttons are listed in the upper right-hand box titled "Interactive Data Layers." Only one layer can be viewed at a time. The buttons are linked to the list of layers that can be viewed on the left-hand side of the program window. The "Measure" tool in Acrobat allows for measuring distances within the selected study area. The "Geospatial Location Tool" (activated with the "Measure" tool) will provide coordinates within the study areas. ---------------------------------------------------------------------------- Suggested citation: Hempel, L.A., Creighton, A.L., and Bock, A.R., 2021, Elevation and elevation-change maps of Fountain Creek, southeastern Colorado, 2015–20: U.S. Geological Survey Scientific Investigations Map 3481, 10 sheets, 12-p. pamphlet, https://doi.org/10.3133/sim3481. ---------------------------------------------------------------------------- DATA RELEASE REFERENCE: Hempel, L.A., Creighton, A.L., and Kisfalusi, Z.D., 2020, Elevation data from Fountain Creek between Colorado Springs and the confluence of Fountain Creek at the Arkansas River, Colorado, 2020 (ver 2.0, May 2021): U.S. Geological Survey data release, https://doi.org/10.5066/P98J7DRO. ---------------------------------------------------------------------------- This map is offered as an online-only, digital publication.
