This dataset describes survey data collected for the Bureau of Reclamation (Reclamation), the agency in charge of regulating Colorado River water control operations impounding the Lake Powell reservoir. Additional intent of the collected data was to assure consistencies among gaging elevations at Glen Canyon Dam near Page, Arizona as well as verification and alignment of a recently published topobathymetric digital elevation model for Lake Powell. Glen Canyon Dam is a concrete arch-gravity dam on the Colorado River in northern Arizona and is the second largest man-made reservoir in the United States. The location was chosen to survey due to uncertainty in the local datum used by the Reclamation as well as uncertainties...

This dataset describes the Survey Data collected for the Planning Assistance to the States (PAS) study along Little Sugar Creek and selected tributaries, near Bella Vista, Arkansas, and Pineville, Missouri, December 2019. Little Sugar Creek is a tributary to the Elk River in Missouri that commences in Benton County, Arkansas and terminates in McDonald County, Missouri. The stream headwaters are located southeast of Garfield, Arkansas. Little Sugar Creek flows through Bella Vista, Arkansas, and runs north to its confluence with the Big Sugar Creek just south of Pineville, Missouri where it forms the Elk River. Browning Creek, Blowing Spring Creek, Spanker Creek and McKisic Creek are all tributaries to the Little...

Digital flood-inundation maps for a 4.46-mile reach of the Blue River near Kansas City, Missouri, were created by the U.S. Geological Survey (USGS) in cooperation with the City of Kansas City, Missouri. The flood-inundation maps, accessed through the USGS Flood Inundation Mapping Program website at http://water.usgs.gov/osw/flood_inundation/ , depict estimates of the spatial extent and depth of flooding corresponding to select-water levels (stages) at the USGS streamgage 06893195 Blue River at Red Bridge Road, Kansas City, Missouri reference streamgage. Near-real-time stage data from the streamgage may be obtained from the USGS National Water Information System database at https://doi.org/10.5066/F7P55KJN. Flood...
Digital flood-inundation maps for a 6.7-mile reach of Joachim Creek within and near the City of De Soto, Missouri, were created by the U.S. Geological Survey (USGS) in cooperation with the City of De Soto, Missouri. The flood-inundation maps depict estimates of the spatial extent, depth, and velocity corresponding to select flood events. Flood elevations were computed for Joachim Creek by means of a two-dimensional, finite-volume numerical model for river hydraulics. The hydraulic model was calibrated by using global positioning system measurements of water-surface elevations of high-water marks from the April 18, 2013 flood and the maximum measured discharge at the USGS streamgage Joachim Creek at De Soto, Missouri...
