Floating aquatic vegetation (FAV) are plants that float freely on or just below the water's surface and with roots that are not attached to a solid substrate but rather float in the water column. Accurate detection of FAV is needed in remotely sensed data products as discrimination between wetland and water classes is hindered in the presence of aquatic vegetation. The spectral...

This dataset contains site information and flood-frequency analysis results using station skew for 253 streamgaging stations operated by the U.S. Geological Survey (USGS) across Colorado within the Rio Grande Basin and Missouri, Arkansas-White-Red, and Upper Colorado River Basins (2- digit hydrologic unit codes 13, 10, 11, and 14, respectively). Some streamgages included in this study...

This data release provides the source data and results of a flood frequency analysis for sites in the Mendenhall River Basin, Alaska, that was conducted using USGS PeakFQ software (Veilleux and others, 2014; Flynn and others, 2006). Data are provided for two streamgages that had at least 10 years of annual peak-flow record. The data include streamgage information, PeakFQ input (.txt and...

This geopackage contains 18 fluvial fish species richness for ~2.3 million stream reaches from the NHDPlusV2.1 in the Conterminous United States. Metrics were developed using 415 fluvial fish species distribution models and highlight four types of summary metrics including all modeled species, migratory species, species of greatest conservation need, and fish species. Nine metrics are...

Flynn Creek crater is a ~3.8 km diameter, >200 m deep, flat-floored impact structure that formed ~360 Ma in what is now north-central Tennessee (36°17’ N, 85°40’ W) [1-4]. Between 1967 and 1979, USGS scientist Dr. David Roddy conducted a drilling program at Flynn Creek crater, an invaluable terrestrial analog that can be applied to the field of planetary impact cratering dynamics [5,6]...

This data release includes six child items with data related to bioenergetics and food web ecology in Shasta Reservoir from 2024 to 2025. Child Item 1: "Zooplankton and Water Temperature Data". This included data on zooplankton density and production (zooplankton_density.csv, zoop_length.csv, and daphnia_egg_ratio.csv) as well as water temperature vertical profiles (temperature_data...

As part of Upper Mississippi River Restoration (UMRR) Program, the U.S. Army Corps of Engineers (USACE) is conducting a study to understand what environmental factors are contributing to the failure of floodplain forests to regenerate. Broken Forest Canopy Identified by Lidar data sets: As part of Upper Mississippi River Restoration (UMRR), the U.S. Army Corps of Engineers (USACE) is...

Impacts of dreissenid mussels (Dreissena spp.) on Great Lakes ecosystems are well documented, but a better understanding of mechanisms that cause variation in mussel abundance is needed. An outstanding question is how much mussel biomass is consumed by predation. To date, attention has mainly focused on invasive Round Goby (Neogobius melanostomus) predation of mussels. Biomass of native

This dataset contains raster layers for environmental characteristics for freshwater habitats including waterbodies (standing water including lakes and wetlands) and streams (moving water) for the contiguous United States. These data can be used to model habitat suitability of non-native species in the contiguous United States. Habitat predictors were developed in four suites: current...

To establish benthic conditions before construction of an Upper Mississippi River Restoration Program habitat restoration and enhancement project (HREP) in Navigation Pool 13, we sampled native freshwater mussels, tubers from watercelery (Vallisneria americana) plants, and surficial sediment with a stratified systematic survey design from 9/24/2024 to 10/4/2024. About 300 sites were...

Eleven pre-established plots within the 2000 Highland Creek Fire perimeter were revisited in 2025 with the purpose of characterizing long-term vegetation recovery as well as present-day fuel loads and forest structure. These research plots were originally established in Wind Cave National Park to assess burn severity using the Composite Burn Index. Additionally, 28 plots established in...

This data release includes raster and text input files to initialize and run the forest disturbance and succession landscape simulation model, LANDIS-II with the Biomass Succession extension for the study area in the Adirondacks (ADK) National Park, New York, USA. The goal of this project was to develop inputs to forecast future spruce-fir forest extent using the landscape model LANDIS...
