The U.S. Geological Survey (USGS), in cooperation with the U.S. Air Force Academy, carried out bathymetry surveys to better characterize the 2019 water-supply capacity of Deadmans Lake; Golf Course Reservoir 9; Ice Lake; Kettle Lakes 1, 2, and 3; and Non-Potable reservoirs 1, 2, 3, and 4 at the U.S. Air Force Academy, Colorado. Survey points from bathymetry and terrestrial datasets were collected using real-time kinematic (RTK) Global Navigation Satellite Systems (GNSS) at each of the aforementioned lakes or reservoirs and merged in geographic information system software, ArcMap, to produce continuous topographic datasets with common horizontal and vertical datums (North American Datum [NAD] 83 and North American...
The U.S. Geological Survey deployed seven submersible pressure transducers on the bottom of the Salcha River in July 2018. An additional transducer was left out of the water to correct for barometric pressure fluctuations. At the time of deployment, the bank position near each transducer and the water-surface elevation were measured with Global Navigation Satellite System (GNSS) equipment. The transducers recorded a depth measurement every 15-min until the recovery of five of the seven in October. We adjusted the water elevation measured at deployment by the difference between the depth measured at deployment and each subsequent depth measurement to derive the water-surface elevation at 15-min intervals. The data...

The U.S. Geological Survey (USGS), in cooperation with the U.S. Air Force Academy, carried out bathymetry surveys to better characterize the 2019 water supply capacity of Deadmans Lake; Golf Course Reservoir 9; Ice Lake; Kettle Lakes 1, 2, and 3; and Non-Potable reservoirs 1, 2, 3, and 4 at the U.S. Air Force Academy, Colorado. The bathymetry surveys were carried out between October 15, 2019, and December 12, 2019, using a man-operated, boat-mounted, single-beam echo sounder integrated with real-time kinematic (RTK) Global Navigation Satellite Systems (GNSS). Terrestrial surveys were carried out during the same time period using RTK GNSS and covered the dry shorelines of lakes and reservoirs. Survey points from...

In 2019, the U.S. Geological Survey, in cooperation with the Upper Colorado River Wild and Scenic Stakeholder Group, studied the magnitude and recurrence interval of streamflow needed to initiate bed movement of gravel-sized and finer sediment in a segment of the Colorado River in Colorado to better understand sediment movement and its relation to flow regimes of the river. Two stationary hydrophone systems were installed on April 23, 2019 at the above Catamount Bridge stationary hydrophone site (above Catamount Bridge site), and two were installed on April 24, 2019 at the Radium stationary hydrophone site (Radium site). Pebble counts of coarse surface particles (greater than 2 millimeters [mm; 0.00656 foot]) were...

Bed movement occurred more frequently and at lower streamflows from State Bridge to Catamount Bridge compared to the study area upstream from State Bridge. Two longitudinal hydrophone profiles were carried out at different streamflows to collect underwater acoustic data using hydrophones throughout the study area on June 6-8, 2019 (June 6-8 longitudinal...

A USGS Unoccupied Aircraft Systems (UAS) Aquatic Airshow field testing and demonstration event occurred March 20–21, 2018, on the Arkansas River at Parkdale, CO, USA. At the airshow, a group of USGS scientists and technicians gathered to test non-contact sensors for measuring stream discharge using UAS and a sensor mounted on a tag line. Scientists at the event performed a series of tests to measure river discharge with experimental non-contact techniques. USGS scientists and field personnel traditionally conduct a discharge measurement either by wading or working from a boat. Due to the potential danger and high risk to personnel safety, hydrologic measurement work is limited during very high flow events, ice break-up,...

This data release includes: the elevation and volumes at specified elevations for each lake or reservoir, combined terrestrial and bathymetry real-time kinematic (RTK) Global Navigation Satellite Systems (GNSS) survey points, and digital elevation models (DEMs) of the lakes and reservoirs. Bathymetric data were collected between October 15, 2019, and December 12, 2019, using a man-operated, boat-mounted,...

A topographic and bathymetric survey was collected along a reach of the Green River downstream of Dinosaur National Monument. The surveyed reach extends approximately 16 kilometers upstream and 6 kilometers downstream of the U.S. Route 40 bridge near Jensen, Utah. The topographic and bathymetric data include survey point data for 382 cross sections over 22 kilometers and are provided as a text file of easting, northing and elevation, in meters. The cross-section location data were collected using real-time kinematic Global Navigation Satellite Systems (GNSS) by USGS personnel from March 26, 2018, through March 29, 2018 using a combination of Sound Navigation and Ranging (SONAR) and wading techniques.

The dataset consists of a .csv and shapefile of measurements of surface velocity magnitude and direction at the Colorado River at Windy Gap near Granby, CO, on June 13, 2022. The dataset contains approximately 2 km of river length. The surface velocity measurements were made by applying Large-Scale Particle Image Velocimetry (LSPIV) techniques, using overlapping videos collected by small Unmanned Aircraft Systems (sUAS). Additional attributes, including divergence, curl, shear, and strain, were calculated from the surface velocity measurements and are included in the dataset. This data is ideal for instantaneous discharge, shear, strain, and divergence, but less so for eddies and mean reach values. This is because...
