Since 1975, annual water use for Louisiana has been published on a 5-year basis and is used for a variety of purposes. As the Sparta aquifer is a heavily used aquifer, is the sole source of groundwater for many parishes in Louisiana, and recent withdrawals have exceeded the Sparta’s natural recharge, a more frequent compilation of water usage for the Sparta aquifer in Louisiana is needed...

The Wyoming-Montana Water Science Center collected continuous gage height data at 30-second intervals at Yellowstone River at Yellowstone Lake Outlet, Yellowstone National Park (YNP), U.S. Geological Survey (USGS) streamgage 06186500, from 2011–2023 in a partnership with the USGS Volcanic Science Center. River gage height data can indicate changes in seismic activity at this location...

The U.S. Geological Survey (USGS) Wyoming-Montana Water Science Center (WY-MT WSC), in collaboration with the USGS Northern Rocky Mountain Science Center (NOROCK), measured streamflow in three headwaters basins in Wyoming and Montana to better quantify streamflow, particularly during lower flows in the late summer and fall. The WY-MT WSC installed two streamgages in each of the three...

This dataset records diel changes to water quality parameters, nutrients, and phytoplankton biomass in the south-eastern region of the Sacramento-San Joaquin Delta. Sampling occurred in August 2024 in the Stockton Waterfront (City of Stockton, San Joaquin County, California, USA) and San Joaquin River. Data was collected from approximately 6am to 9pm Pacific Standard Time on August 6, 13...

A 2D HEC-RAS hydraulic model was developed to simulate flow velocities and shear stresses within a reach of the Kalamazoo River in southeastern Michigan from the Trowbridge Dam to the Allegan City Dam. The development of the 2D HEC-RAS model is described in the associated U.S. Geological Survey Scientific Investigations Report 2025-XXXX. This model archive contains all the files needed...

These data include annual instantaneous maximum discharge record for 156 streams and rivers in Vermont and adjacent areas of New Hampshire, Massachusetts, and New York through the 2023 water year. The data also include flood-frequency estimates for the 50-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance probabilities that were analyzed using the discharge data. These flood...

Data in this release include oviposition, pipping, body size, and environmental temperature observations for three wild adult female Burmese pythons (Python molurus bivittatus). Data are from two individuals that were free-ranging (Pythons # 1 and 2) in Big Cypress National Preserve, Collier County, Florida, USA and one wild-caught individual (Python #3) placed in an outdoor enclosure on...

We collected aquatic macroinvertebrate and redband trout (Oncorhynchus mykiss newberrii) diet data in the Oregon portion of the Goose Lake Basin. Data were collected by the U.S. Geological Survey (USGS) and Oregon State University (OSU) to monitor prey communities in the Basin, and to relate observed prey abundances to specific habitat features. Sampling was conducted based on previous...

The layered mafic and ultramafic Stillwater Complex in southwest Montana is known for its platinum-group element (PGE) production from reef-style mineralization (J-M Reef) in the Lower Banded series. Rocks near the base of the complex—the Basal series and Ultramafic series, Peridotite zone—also host elevated concentrations of Ni, Cu, Co, Cr, and PGE. These rocks of the complex’s lower...

This data release consists of flood hazard maps from compound coastal hazards--specifically sea-level rise (SLR) and projected coastal storms. Products include projected flood depths, flood extents including uncertainties, water elevations, wave heights, velocity hazards, and erosion and sedimentation patterns. These are generated using a suite of numerical models driven by outputs from...
