Data

This U.S. Geological Survey (USGS) data release contains continuous data from the Roaring Fork, Colorado, cosmic-ray neutron sensor (CRNS) soil moisture monitoring network as well as supplemental soil laboratory analyses and discrete field-based measurements collected in 2023 and 2024 for calibration and validation of CRNS data. The network includes 15 CRNS stations located in the...

The U.S. Geological Survey collected low-altitude airborne natural color imagery, surface temperatures and multispectral imagery via a hexacopter uncrewed aircraft system (UAS) for mapping Hoxworth Springs, Clark Well and Buck Springs in the Coconino National Forest in Arizona. Visual imagery was collected in jpg (for color imagery) and TIFF (for thermal imagery and multispectral imagery...

This data release contains audio data collected from 2021 to 2024, expanding on the dataset collected for a 2019 U.S. Geological Survey (USGS) study which tested the use of hydrophones to detect bedload mobilization and identify a streamflow threshold at which bedload began to mobilize in the Upper Colorado River (Kohn and others, 2020). Child item "Stationary Hydrophone Data collected...

This data release contains sensor-based water-quality and discrete stable isotopes of water data collected along the Upper Colorado River. Data collection was made by the University of Colorado at Boulder, Colorado (CO), and the U.S. Geological Survey (USGS) in Lakewood, CO. The water-quality data were collected from an inflatable raft during 5 high flow and 3 low flow sampling campaigns...

Geothermal springs may be connected to both shallow and deep groundwater sources, and identification of variable spring sources may assist with resource management of geothermal systems. Numerous geothermal springs exist near the Yampa River in Steamboat Springs, Colorado and local water and land management agencies could benefit from information on the sources of these springs. This...

Regression models were developed with reflectance values from remote-sensing imagery and concurrent turbidity measurements during a 2 year period at Colorado River near Cameo, Colorado streamgage (U.S. Geological Survey station number 09095500). Three types of remote sensing systems were tested including satellite- and ground-based sensors. Models relate the explanatory variables...

The U.S. Geological Survey, in cooperation with Colorado Springs Utilities, has been collecting topographic data annually since 2012 at 10 study areas along Fountain Creek, Colorado. The 10 study areas are located along Fountain Creek between Colorado Springs and the confluence of Fountain Creek and the Arkansas River in Pueblo. This data release presents topographic survey data, Light...

Blue Mesa Reservoir (Blue Mesa) is the largest storage reservoir in Colorado and is used for water supply and recreation. The reservoir consists of three distinct basins which are, moving from east to west, Iola, Cebolla, and Sapinero. This data release includes a wide variety of data collected to understand conditions that contribute to algal blooms in Blue Mesa. Data include...

From 2022 through 2024, the U.S. Geological Survey (USGS) conducted a study in cooperation with the Arkansas River Basin Regional Resources Planning Group (Southeastern Colorado Water Conservancy District, Colorado Springs Utilities, Pueblo Water, Lower Arkansas Valley Water Conservancy District, Aurora Water, and Upper Arkansas Water Conservancy District) to establish a basin-wide water...

These datasets were collected by a ground penetrating radar unit installed on small Uncrewed Aircraft Systems (sUAS). Data include the two-way travel time (TWTT) for the ground surface (distance between the snow-ground interface and sUAS) and the calculated snow depth. The snow depth TWTT is defined as the time duration in nanoseconds that the electromagnetic wave takes to travel from...

This data release contains the input and output used to assess the potential effect of climate on streamflow and salinity (measured as total dissolved solids [TDS]) yields across the Upper Colorado River Basin from water years 1986 to 2021. This analysis included estimation of the spatiotemporal variability in mean annual climatic variables (air temperature, snow water equivalent...

This U.S. Geological Survey (USGS) data release provides the data used to predict areas with the greatest probability of ephemeral stream channel instability on north side of the Grand Valley in western Colorado, during 2018-20. The USGS developed a method for automatically extracting channel cross-section geometry from existing remotely sensed terrain models. Based on estimated flood...
