Data

The U.S. Geological Survey (USGS) collected stream samples at 19 sites in tributaries to the Upper Delaware Scenic and Recreational River during 2012-15 in cooperation with the National Park Service (NPS) through the USGS-NPS Water-Quality Partnership to provide data on existing water-quality in small watersheds not previously characterized and where there was potential for...

Water was sampled in streams from Butte to near Missoula, Montana, as part of a long-term monitoring program in the upper Clark Fork Basin. The sampling program was completed by the U.S. Geological Survey (USGS), in cooperation with the U.S. Environmental Protection Agency, to characterize aquatic resources in the upper Clark Fork Basin and monitor trace elements associated with...

Fort Irwin National Training Center uses treated groundwater for both drinking and irrigation purposes. Wastewater is treated locally at Fort Irwin National Training Center using tertiary treatment methods and the treated wastewater effluent is discharged into percolation ponds and allowed to percolate into the local groundwater system. Specific conductance, total dissolved solids...

This dataset includes water-quality and sediment data for 647 environmental samples collected at 53 surface-water sites in Cache Creek (Cache C) watershed, Yolo County, California, between December 2009 and April 2019, and data for 190 associated quality-control samples (replicates and blanks). About 90 percent of the samples were collected at the following six primary sites that were...

Water, bed sediment, and invertebrate tissue were sampled in streams from Butte to near Missoula, Montana, as part of a long-term monitoring program in the upper Clark Fork Basin. The sampling program was completed by the U.S. Geological Survey (USGS), in cooperation with the U.S. Environmental Protection Agency, to characterize aquatic resources in the upper Clark Fork Basin and monitor...

The U.S. Geological Survey (USGS), in cooperation with the Montana Department of Transportation (MDT), collected water-surface profile data at selected highway bridges in Montana. The water-surface profile data characterizes the water-surface elevation and slope upstream and downstream of a bridge. Water-surface profile data were typically obtained for one side of the stream by surveying...

This dataset includes nest abundance of American avocets (Recurvirostra americana), black-necked stilts (Himantopus mexicanus), and Forster's terns (Sterna forsteri) in south San Francisco Bay, California by year. It also contains California gull (Larus californicus) hazing research efforts. This dataset was generated from yearly nest monitoring surveys within wetlands in south San...

Waterfowl were observed staging at Nanvak Bay, Togiak National Wildlife Refuge in southwest Alaska between 31 August and 27 September 1992. This data release contains five tables including 1) aerial surveys, 2) band resights for Black Brant (Branta bernicla nigricans), 3) Black Brant age ratios, 4) bird migration observations, and 5) taxonomy table for observed birds.

Heavy fog was hypothesized to interfere with flight of waterfowl by obscuring visibility and cause waterfowl to fly more in search for habitat below, which in turn, is likely to increase bioenergetic (caloric) cost related to increased time flying. The data sets include variables used to analyze the relationship between fog characteristics (occurrence, density, and longevity) and flight...

The Chesapeake Stream Team studied 123 streams from 2021 to 2024 to determine whether conservation practices in agricultural and urban settings have improved downstream nontidal stream health. To isolate effects of conservation practices, scientists must account for other attributes in the greater watershed that may affect measured metrics of stream health. This release includes over 450

These data files have information for hydrologic features contained in the Watershed Boundary Dataset (WBD) feature datasets. The datasets include information about the 12-digit HUC polygons for the USGS Regional Integrated Methods for Base Evaluation (RIMBE) of five Integrated Water Science (IWS) study areas: Delaware River Basin (DRB), Illinois River Basin (IRB), Trinity-San Jacinto...

This data release (DR) is the update of the U.S. Geological Survey - ScienceBase DR (Bera, 2024b), with the processed data for the period October 1, 2022, through September 30, 2023. This DR describes the watershed data management (WDM) database file SC23.WDM. The precipitation data are collected from a tipping-bucket rain-gage network and the hydrologic data (stage and discharge) are...
