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...

Backward particle tracking in groundwater was simulated with MODPATH and the MODFLOW groundwater flow model by Long and others (2024). Simulated particles were tracked backward from well intakes in areas within or near Joint Base Lewis-McChord (JBLM) for the purpose of determining their likely points of origin within groundwater recharge areas. Steady-state and transient simulations were...

This data release contains Global Navigation Satellite System (GNSS) measurements acquired across five Texas coast National Wildlife Refuges in 2024. These data will be used to establish vertical control and tie rod-set elevation table (RSET) data to the National Spatial Reference System (NSRS) and National Vertical Datum of 1988 (NAVD88). Data from the RSETs will be used to determine...

This dataset includes high-resolution thermal infrared (TIR) and true-color images collected from crewed aircraft and a point shapefile and corresponding comma-delimited tabular data representing the longitudinal spatial patterns of surface water temperature in the surveyed streams in the Santiam River Basin, Oregon. The aerial surveys were contracted through Watershed Sciences, LLC by...

This report includes whole rock geochemical data from a newly collected suite of samples from igneous systems across Arizona. The data release includes samples collected in calendar year 2024 that support an ongoing, multi-year project dedicated to characterizing magmatic porphyry systems toward understanding possible basement influence on porphyry style mineralization. This preliminary...

At the Rockbridge Stone Products sand and gravel open pit mine along Loves Run, two Optically Stimulated Luminescence samples from an f2 fan deposit yielded dates from ca. 157 to 139 ka (Carter and others, 2017). These two ages were used to define the Pleistocene map units within the quad.

New bedrock and surficial geologic mapping in the Blue Ridge of NW NC and SW VA covers the Sparta East, Sparta West, and parts of the Glade Valley and Whitehead 7.5-minute quadrangles and includes the epicentral area of the 9 August 2020 Mw 5.1 earthquake near Sparta, NC. Mapping documented (1) the co-seismic surface rupture from the 2020 earthquake and brittle structures in the bedrock...
