Acoustic, Spatial, and Sediment Size Data Collected on the Upper Colorado River to Estimate the Flushing Flows, Colorado, 2019 Acoustic, Spatial, and Sediment Size Data Collected on the Upper Colorado River to Estimate the Flushing Flows, Colorado, 2019
In 2019, the U.S. Geological Survey, in cooperation with the Upper Colorado River Wild and Scenic Stakeholder Group, studied the magnitude and frequency of streamflow needed to initiate bedload transport of gravel-sized and finer sediment on the Colorado River to maintain spawning habitat for fish and maintain substrate and interstitial spaces for benthic macroinvertebrates. Bedload...

Data for Fluoride Occurrence in United States Groundwater Data for Fluoride Occurrence in United States Groundwater
Data from 38,105 wells were used to characterize fluoride occurrence in untreated United States groundwater. The data were retrieved from the U.S. Geological Survey (USGS) National Water Information System (NWIS). Groundwater samples were collected from 1988 to 2017 in the conterminous United States. Data for groundwater included in this dataset are pH, water temperature, and...
