Dabbling Duckling Habitat Use and Movements Dabbling Duckling Habitat Use and Movements
We conducted a multi-year study (2016-2019) to identify elements of wetland habitat management that could potentially benefit breeding ducks. Specifically, we examined the influence of habitat variables in explaining habitat selection of managed wetlands near upland nesting sites by radio-tagged Mallard (Anas platyrhynchos) and Gadwall (Mareca strepera) ducklings in a brackish marsh...
Estimated Annual Recharge to the Edwards Aquifer in the San Antonio Area, by Stream Basin or Ungaged Area, 1934–2023 Estimated Annual Recharge to the Edwards Aquifer in the San Antonio Area, by Stream Basin or Ungaged Area, 1934–2023
The Edwards aquifer in south-central Texas is one of the most permeable and productive aquifers in the United States and is the major source of public water supply for Bexar, Comal, Hays, Medina, and Uvalde Counties. The Edwards aquifer also supplies large quantities of water for use in agriculture, business, and industry in the region. The major artesian springs of the Edwards aquifer...
Physical and hydraulic monitoring on the Yellowstone River fish bypass channel, Montana Physical and hydraulic monitoring on the Yellowstone River fish bypass channel, Montana
This data release was produced by the U.S. Geological Survey (USGS) in cooperation with the Bureau of Reclamation (Reclamation) to present the results of monitoring efforts on the Yellowstone River fish bypass channel according to the specifications of the Lower Yellowstone Adaptive Management and Monitoring Plan. The fish bypass channel was constructed to provide upstream migrating fish...
Whole rock geochemical data for ore and host rock for select iron oxide-apatite and iron oxide-copper-gold deposits found in the Basin and Range province of California, Nevada, and Utah collected 2023-2024 Whole rock geochemical data for ore and host rock for select iron oxide-apatite and iron oxide-copper-gold deposits found in the Basin and Range province of California, Nevada, and Utah collected 2023-2024
This data release encompasses whole rock geochemical data determined on iron ore and host rock samples collected in California, Nevada, and Utah from March 2023 through June 2024. Whole rock geochemistry was conducted on 269 samples. Major element oxides were determined by borate fusion and wavelength dispersion X-ray fluorescence; 61 elements were determined by sodium peroxide fusion...
Mechanisms of Devils Lake’s Responses to Recent Climatic Wetting: Insights from a Physically Based Hydrologic Model Mechanisms of Devils Lake’s Responses to Recent Climatic Wetting: Insights from a Physically Based Hydrologic Model
These data cover Devils Lake Basin of Northern Great Plains (NGP) region, North Dakota. We aimed to understand the mechanism of the Devils Lake responses and basin-wide hydrologic change under a wet-climatic regime using a process-based and cold region hydrologic model. The data include areal measurements (km2) of each of the Hydrological Response Units (HRUs) that were modeled.
Data for Analysis of Decadal Trends in the Quality of Groundwater Used for Public Drinking-Water Supply in California, 2004-2023, California GAMA Priority Basin Project Data for Analysis of Decadal Trends in the Quality of Groundwater Used for Public Drinking-Water Supply in California, 2004-2023, California GAMA Priority Basin Project
This data release documents datasets supporting analysis of decadal trends in the quality of groundwater resources used for public drinking-water supply across California. The analysis primarily utilizes samples collected by the U.S. Geological Survey's Groundwater Ambient Monitoring and Assessment Priority Basin Project (GAMA-PBP) during 2004-2023 as part of a cooperative research...
