The Fluvial Egg Drift Simulator (FluEgg) estimates bighead, silver, and grass carp egg and larval drift in rivers using species-specific egg developmental data combined with user-supplied hydraulic inputs (Garcia and others, 2013; Domanski, 2020). This data release contains results from 240 FluEgg 4.1.0 simulations of bighead carp eggs in the Illinois River under steady flow conditions...

Grass Carp Ctenopharyngodon idella was imported to the United States in the 1960s for research into its usefulness as a biocontrol agent for nuisance aquatic vegetation. Escapees and intentionally stocked individuals founded wild, spawning populations in the Mississippi River and tributaries to the Laurentian Great Lakes. USGS-led research on the Sandusky River, a tributary to Lake Erie

This data release contains trend results computed on the basis of modeled and observed daily streamflows at 502 reference gages across the conterminous U.S. from October 1, 1983 through September 30, 2016. Modeled daily streamflows were computed using the deterministic Precipitation Runoff Modeling System (PRMS), and five statistical techniques: Nearest-Neighbor Drainage Area Ratio...

These data were compiled for research pertaining to the effects of stand density treatments on growth rates in semi-arid, ponderosa pine forests. Also, these data examined how the planned restoration treatments in the Four Forests Restoration Initiative (4FRI), the largest forest restoration project being implemented in the United States, would alter landscape-scale patterns of forest...

On August 25, 2020, the U.S. Geological Survey conducted a bathymetry survey of a 550 meter long reach of the Black River near Great Bend, New York. The study reach began approximately 1,000 meters upstream from the State Route 26 bridge in Great Bend, New York. Depth data were collected primarily with a 1,200 kilohertz Teledyne RD Instruments RioPro acoustic Doppler current profiler...

This data release includes tabular data files. The dataset consists of four input data tables (Appendices A1-A4) for a Lake Superior EcoPath with EcoSim (EwE; http://ecopath.org) model parameterized to the early 21st century using 2001-2016 collections. The data presented here are primarily intended to development a static ecosystem model representing a snapshot of Lake Superior circa...

This dataset describes water-quality data measured from the parking lot influent and underdrain and overflow effluent from the porous asphalt, pervious concrete, and permeable interlocking concrete paver test plots in Madison, Wisconsin, USA. Data include precipitation statistics; influent, overflow, and underdrain volumes; and concentrations and loads of total and dissolved forms of...

Aerial imagery acquired with a small unmanned aircraft system (sUAS), in conjunction with surveyed ground control points (GCP) visible in the imagery, can be processed with structure-from-motion (SfM) photogrammetry techniques to produce high-resolution orthomosaics, three-dimensional (3D) point clouds and digital elevation models (DEMs). This dataset, prepared by the U.S. Geological...

The Philadelphia Water Department (PWD) and USGS worked together on the groundwater level monitoring network for Philadelphia.

This dataset documents the gene transcription levels for a panel of 12 selected genes and the heat shock protein 70 (HSP70) protein abundance measured in the muscle tissue of individual wild Chinook salmon captured from locations within the U.S. portion of the Yukon River watershed. Chinook salmon were primarily captured in 2016 and 2017 from existing field efforts (n = 477). A small...

Water provides society with economic benefits that increasingly involve tradeoffs, making accounting for water quality, quantity, and their corresponding economic productivity more relevant in our interconnected world. In the past, physical and economic data about water have been fragmented, but integration is becoming more widely adopted internationally through application of the System...

The U.S. Geological Survey (USGS), in cooperation with Connecticut Department of Transportation, completed a study to improve flood-frequency estimates in Connecticut. This companion data release is a Microsoft Excel workbook for: (1) computing flood discharges for the 50- to 0.2-percent annual exceedance probabilities from peak-flow regression equations, and (2) computing additional...
