Geochemical and hydrologic data supporting assessment of a low-temperature geothermal system in Steamboat Springs, Colorado Geochemical and hydrologic data supporting assessment of a low-temperature geothermal system in Steamboat Springs, Colorado
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...
Input and Output files from the Zonebudget program used with MODFLOW models to compute regional groundwater budgets for the Virginia Coastal Plain aquifer system Input and Output files from the Zonebudget program used with MODFLOW models to compute regional groundwater budgets for the Virginia Coastal Plain aquifer system
This data release contains results from annual water budgets computed for two groundwater-flow models of the Virginia Coastal Plain published by the Virginia Department of Environmental Quality (Virginia Department of Environmental Quality, 2020, 2024a and 2024b). Both models simulated historical withdrawals from approximately 1900 to 2023 and projected withdrawal conditions to 2073...
Geochemical data for rock, sediment, soil, and mineral samples, United States and territories, 1962 to 2023 Geochemical data for rock, sediment, soil, and mineral samples, United States and territories, 1962 to 2023
The data set contains geochemical data for 1,524,014 rock, sediment, soil, and mineral samples collected by the U.S. Geological Survey within US state, territory or Economic Exclusive Zone (EEZ) boundaries, and analyzed from 1962 through 2023 either in the analytical laboratories of the Geologic Discipline of the USGS or by contract with commercial analytical laboratories. These data...
Historical (1900s-1940s) and present-day (2003 – 2023) spring Chinook salmon (Oncorhynchus tshawytscha) spawning distribution in the Willamette River Basin, Oregon Historical (1900s-1940s) and present-day (2003 – 2023) spring Chinook salmon (Oncorhynchus tshawytscha) spawning distribution in the Willamette River Basin, Oregon
Spawning distribution maps for Upper Willamette River (UWR) spring Chinook salmon were created for the historical period (approximately 1910-1940), and for the present-day period (2003-2023). These maps were created as a tool to visualize generalized, reach-scale patterns of spawning distribution before and after the construction of high-head dams and other large-scale anthropogenic...
PIT tagging and detection of Chinook salmon (Oncorhynchus tshawytscha) in cold water refuges of the Klamath River PIT tagging and detection of Chinook salmon (Oncorhynchus tshawytscha) in cold water refuges of the Klamath River
We conducted a pilot study to evaluate the extent of cold water refuge use by juvenile outmigrating fall-run Chinook salmon (Oncorhynchus tshawytscha) in relation to managed water flows in the Klamath River. Juvenile fall-run Chinook salmon were captured and implanted with passive integrated transponder (PIT) tags and subsequently detected by submersible antennas that were strategically...
Model output and code for a long short-term memory model forecasting streamflow drought across the Conterminous United States by focusing on percentiles below 50 percent Model output and code for a long short-term memory model forecasting streamflow drought across the Conterminous United States by focusing on percentiles below 50 percent
Machine learning (ML) models were used to forecast streamflow drought from 1 to 13 weeks into the future at more than 3,000 streamgage locations across the conterminous United States. Long short-term memory [LSTM] neural network models were used to predict weekly streamflow percentiles with independent models for each forecast horizon. In this data release we specifically include an LSTM...
