Synoptic sampling data from Illinois Gulch and Iron Springs near Breckenridge, Colorado, August 2016 and September 2017

Two synoptic sampling campaigns were conducted near Breckenridge, Colorado, to quantify metal loading to Illinois Gulch, a tributary of the Blue River. The first campaign, conducted in August 2016, was designed to determine the degree to which Illinois Gulch loses water to the underlying mine workings, and to determine the effect of these losses on observed metal loads. The second campaign,...

Model output from Precipitation-Runoff Modeling System simulations in the Rio Grande Headwaters, Colorado, for water years 1980 through 2017

The U.S. Geological Survey Precipitation-Runoff Modeling System (PRMS) was used to assess the effects of changing climate and land disturbance on seasonal streamflow in the Rio Grande Headwaters (RGHW) region. Three applications of PRMS in the RGHW were used to simulate 1) baseline effects of climate (see RGHW-PRMS_baseline_simulation.zip), 2) effects of bark-beetle induced tree mortality (see...

Nutrient and algal response values from a mesocosm experiment used to estimate algal growth rates

These data have been collected as part of a cooperative project between the U.S. Geological Survey (USGS) and the U.S Environmental Protection Agency. This project began in 2016 and consisted of a mesocosm experiment quantifying short term responses by a transplanted natural diatom dominant algae community exposed to gradients of nitrogen, phosphorous, and a mixture of both nitrogen and...

Drainage basins and characteristics for selected streamgages within the Southern Rockies Landscape Conservation Cooperative domain

Streamflow and basin-characteristic data are needed for a variety of scientific applications including estimation of flow in ungaged basins and hydro-ecological classification of rivers. The U.S. Geological Survey (USGS), in cooperation with the Bureau of Reclamation and the Southern Rockies Landscape Conservation Cooperative (SRLCC), selected a subset of streamgages across the SRLCC domain...

Fortran Program for Estimating Stream Transit Losses of Reusable Water, El Paso and Pueblo Counties, Colorado

The transit-loss accounting program, which has been in continuous daily use in some form since April 1989, has provided water-rights administrators with a tool to effectively manage RRFs and administer water diversion priorities along Fountain Creek on a daily basis.

Continuous resistivity profiling, direct current resistivity, and frequency domain electromagnetic data for the Dolores River, Paradox Valley, Colorado, 2017

This data release includes raw and processed (inverted) data for three different geophysical methods, continuous resistivity profiles (CRP), direct current electrical resistivity tomography (ERT), and frequency domain electromagnetic induction (FDEM) data. These surface geophysical methods were used as a proxy for groundwater salinity in the Paradox Valley in western Colorado to investigate...

Surface Materials Data from Breccia-Pipe Uranium Mine and Reference Sites, Arizona, USA

This data release includes elemental analysis of soil samples collected at breccia-pipe uranium mines, at one undeveloped breccia-pipe uranium deposit, and at a reference site in northern Arizona. Samples were collected near the Arizona 1, Canyon, Kanab North, and Pinenut uranium mines, over the EZ2 breccia-pipe uranium deposit, and at the Little Robinson Tank reference site. Samples were...

Cross-Section Geometry and Sediment-Size Distribution Data from Muddy Creek and North Fork Gunnison River below Paonia Reservoir, western Colorado, 2018

This dataset contains cross-section geometry and sediment-size distribution data collected in the fall of 2018 from Muddy Creek and North Fork Gunnison River below Paonia Reservoir, western Colorado. Six cross-sections were surveyed using Real-Time Kinematic Global Navigation Satellite System (RTK-GNSS) methods to document channel geometry below the reservoir in 2015. Those same cross-sections...

Current Streamflow and Water-Quality Monitoring at Select Sites in the Animas and San Juan River Basins, Colorado, New Mexico, and Utah

The USGS monitors current streamflow and water-quality conditions at various sites in the Animas and San Juan River Basins in Colorado, New Mexico, and Utah, including areas below the Gold King Mine release area. These streamgages provide continuous data on streamflow and select water-quality constituents including specific conductance, water temperature, pH, and turbidity.
