Data used to prioritize the selection of river basins for intensive monitoring and assessment by the U.S. Geological Survey Data used to prioritize the selection of river basins for intensive monitoring and assessment by the U.S. Geological Survey
The U.S. Geological Survey (USGS) developed a systematic, quantitative approach to prioritize candidate basins that can support the assessment and forecasting objectives of the major USGS water science programs. Candidate basins were the level-4 hydrologic units (HUC4) with some of the smaller HUC4s being combined (hereafter referred to as modified HUC4 basins). Candidate basins for the...
Geospatially derived environmental characteristics to prioritize watersheds for research and monitoring needs within 18 hydrologic regions across the United States Geospatially derived environmental characteristics to prioritize watersheds for research and monitoring needs within 18 hydrologic regions across the United States
Water availability for human and ecosystem needs is a function of both water quantity and water quality, as described in the U.S. Geological Survey (USGS) Water Science Strategy (Evenson and others, 2013). Recently, a quantitative approach to prioritize candidate watersheds for monitoring investment was developed to understand changes in water availability and advance the objectives of...
Geochemical and fallout radionuclide data for sediment source fingerprinting studies of the Loutsenhizer Arroyo and Sunflower Drain watersheds in western Colorado Geochemical and fallout radionuclide data for sediment source fingerprinting studies of the Loutsenhizer Arroyo and Sunflower Drain watersheds in western Colorado
This data release includes geochemical and fallout radionuclide data for suspended sediments and potential sediment source types for the Loutsenhizer Arroyo and Sunflower Drain watersheds in western Colorado. Suspended sediments were collected by passive samplers deployed in the stream channel of the watershed outlets during four study periods between August 2018 and August 2019...
NGWOS Ground-Based Discrete Snowpack Measurements Data Release (ver. 2.0, March 2026) NGWOS Ground-Based Discrete Snowpack Measurements Data Release (ver. 2.0, March 2026)
Ground-based discrete snowpack measurements were collected during winter field campaigns starting in 2020. These data were collected as part of the U.S. Geological Survey (USGS) Next Generation Water Observing System (NGWOS) Upper Colorado River Basin project focusing on the relation between snow dynamics and water resources. This data release consists of three child items. Each child...
Basin Characteristics and Salinity and Selenium Loads and Yields for Selected Subbasins in the Lower Gunnison River Basin, Western Colorado, 1992─2013 Basin Characteristics and Salinity and Selenium Loads and Yields for Selected Subbasins in the Lower Gunnison River Basin, Western Colorado, 1992─2013
Mitigating the effects of salinity (total dissolved solids) and selenium on water quality in the lower Gunnison River Basin (LGRB) of western Colorado is a major concern for land managers. In cooperation with the Bureau of Reclamation, the U.S. Geological Survey completed a study to develop multiple linear regression models to estimate salinity and selenium loads. The objective of the...
Analytic-element groundwater-flow model of the Captain Jack Superfund Site, Boulder County, Colorado Analytic-element groundwater-flow model of the Captain Jack Superfund Site, Boulder County, Colorado
The U.S. Geological Survey (USGS) used an analytic-element method (AEM) modeling approach to quantitatively understand groundwater dynamics at the Captain Jack Superfund Site, located in Boulder County, Colorado. The Captain Jack Superfund Site hosts extensive interconnected underground mine workings.The U.S. Environmental Protection Agency has instituted a remedial strategy of...
Channel Characteristics, benthic algae, and water quality model data for selected sites in the upper White River Basin, Colorado, 2018-21 Channel Characteristics, benthic algae, and water quality model data for selected sites in the upper White River Basin, Colorado, 2018-21
This U.S. Geological Survey (USGS) data release provides benthic algae and stream channel characteristics data collected from 20 water-quality sites in the Upper White River Basin, Colorado., during 2018-2021. Also included are input and output data from streamflow and water-quality regression models used to characterize streamflow and water-quality conditions at 3 sites in the Upper...
Cross-section geometry and sediment-size distribution data from the Upper Colorado River, April 6-8, 2022 Cross-section geometry and sediment-size distribution data from the Upper Colorado River, April 6-8, 2022
The U.S. Geological Survey collected geomorphic monitoring data in cooperation with the Upper Colorado River Wild and Scenic Stakeholder Group. This data release contains cross-section geometry and sediment-size distribution data collected from five sites on the Upper Colorado River, Colorado during April 6-8, 2022. The five sites selected for monitoring were located at the Pumphouse...
Elevation Data from Fountain Creek between Colorado Springs and the Confluence of Fountain Creek at the Arkansas River, Colorado, 2022 Elevation Data from Fountain Creek between Colorado Springs and the Confluence of Fountain Creek at the Arkansas River, Colorado, 2022
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...
