Validation of gridded precipitation datasets for flood-typing in six basins in the contiguous U.S. Validation of gridded precipitation datasets for flood-typing in six basins in the contiguous U.S.
The U.S. Geological Survey (USGS) and the U.S. Army Corps of Engineers (USACE) are collaborating with the U.S. Federal Emergency Management Agency (FEMA) on improving flood-frequency analysis methods to account for mixed populations arising from different flood causal mechanisms. Precipitation data at different timescales are widely used in flood-typing studies. Various gridded...
Inputs and outputs of 3D point-cloud comparisons (M3C2) from repeat bathymetric and topographic surveys from 2019 – 2022 of the French Broad River, Asheville, NC Inputs and outputs of 3D point-cloud comparisons (M3C2) from repeat bathymetric and topographic surveys from 2019 – 2022 of the French Broad River, Asheville, NC
This data release provides the input and output datasets used to inform geomorphic change detection (GCD) analyses from repeat streambank and streambed surveys of a one-kilometer reach of the French Broad River (FBR) where the NCDOT initiated a highway widening and bridge construction project in 2020 near Asheville, North Carolina (Whaling, 2023a–d; Whaling and Wagner, 2021; Whaling and...
Digital elevation models with elevation uncertainty treatment, Grand Bay Estuary, Mississippi, 2015 - 2022 Digital elevation models with elevation uncertainty treatment, Grand Bay Estuary, Mississippi, 2015 - 2022
This data release includes outputs that were created using Monte Carlo simulations with the aim to reduce elevation overestimation in coastal wetlands at Grand Bay, MS. We evaluated the performance of coastal wetland elevation refinement by using bare earth digital elevation models (DEMs) and DEMs created from the last return from the light detection and ranging (lidar) point cloud...
Code and outputs for a mallard reproduction model incorporating migration delays and reduced adult body mass Code and outputs for a mallard reproduction model incorporating migration delays and reduced adult body mass
These data are outputs from a mallard (Anas platyrhynchos) reproduction model that accounts for breeding ground arrival time and the body mass of individuals. Specifically, adult female mallards that arrive late or with lower body mass have the potential for lower clutch sizes and are less likely to renest if a nest fails. The model is based on an existing mallard reproduction model that...
CoSMoS-AK Modeled flood and erosion hazards at Golovin- Coastal Alaska CoSMoS-AK Modeled flood and erosion hazards at Golovin- Coastal Alaska
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 hazard, and erosion and sedimentation pattern. These are generated using a suite of numerical models driven by outputs from...

Phytoplankton identification and enumeration data within an algal bloom at Lost Bay, Kabetogama Lake, northern Minnesota, 2022 Phytoplankton identification and enumeration data within an algal bloom at Lost Bay, Kabetogama Lake, northern Minnesota, 2022
This data release provides phytoplankton identification and enumeration data from an algal bloom at Lost Bay on Kabetogama Lake (USGS site ID 482747092503001) collected on September 20, 2022. These data were collected using a systematic grid design, 3 rows by 4 columns grid cells, where each grid cell contained a single sample location. A near-shore sample location, just outside the...
Acoustic-tagged juvenile late-fall Chinook salmon (Oncorhynchus tshawutscha) detections in Shasta Reservoir, McCloud River, CA, 2017-2018, 2024-2025 Acoustic-tagged juvenile late-fall Chinook salmon (Oncorhynchus tshawutscha) detections in Shasta Reservoir, McCloud River, CA, 2017-2018, 2024-2025
Three studies were conducted in Shasta Reservoir in California to evaluate downstream migration and behavior of juvenile late-fall run Chinook salmon (Oncorhynchus tshawutscha) released in the McCloud River upstream of Shasta Dam in Spring 2017, Fall 2017, and Fall 2024. The goal of this study was to collect data beneficial for citing a juvenile salmon collection system for downstream...
Model Outputs Showing Optimized Grassland Restoration Sites in the Great Plains Region of Kansas Model Outputs Showing Optimized Grassland Restoration Sites in the Great Plains Region of Kansas
Ecological restoration is essential to meet global biodiversity conservation goals. Given limited conservation budgets, deciding where to restore habitat is a key challenge for the coming decade. This dataset includes optimal restoration sites selected from multiple restoration model scenarios. We developed a modeling approach to maximize conservation benefit/restoration cost ratios to...
LANDFIRE 2001 Base Map LANDFIRE 2001 Base Map
The LANDFIRE (LF) 2001 (version 1.0.5) Refresh of the LF National Base Map enhanced the layers of the LF National data set to provide a foundation upon which to build an updated geospatial data set. The enhancements were developed to facilitate comparative analyses, evaluate trends, and potentially monitor changes over time. In particular, LF 2001 enhancements addressed: incomplete data...
USGS Data for the Characterization of Radionuclides in Waste Byproducts Prior to Land Application in the United States USGS Data for the Characterization of Radionuclides in Waste Byproducts Prior to Land Application in the United States
Land applied waste byproducts were collected by USGS from 34 sites across the United States. Materials included waste byproducts from treatment of municipal sewage (biosolids), production of food (bovine, poultry, and swine wastes), and drilling of oil and gas wells (spent oil- and water-based drilling fluids). The samples represent 10 municipal wastewater treatment plants, 11 animal...
