Clackamas River Basin Water-Quality Sites
Recent and historical data for USGS Clackamas River Basin water-quality monitors.
Geologic map of the Strawberry Butte 7.5' quadrangle, Meagher County, Montana
The Strawberry Butte quadrangle, scale 1:24,000, is a legacy map of the U.S. Geological Survey, made as part of the Montana Investigations Project to provide information on the stratigraphy, structure, and geologic history of the area. The quadrangle encompasses an area of about 132 km2 (51 mi2) in the southwest part of the Little Belt Mountains and is about 26 km (17 mi) north of White Sulphur Sp
Cottonwood Lake Study Area - Invertebrate Counts
This dataset contains macroinvertebrate sampling data for the wetlands in the Cottonwood Lake Study Area, Stutsman County, North Dakota. This dataset is part of the Missouri Coteau Wetland Ecosystem Observatory database that is a collection of abiotic and biotic data documenting biotic and abiotic responses to long-term climate and land-use change in the Prairie Pothole Region (PPR) of the U.S. Th

Biological and physical data for zebra mussel (Dreissena polymorpha) veligers collected from a coupled lake-stream ecosystem in north Texas, 2012-2014
Dispersal, establishment, and spread of aquatic invasive species such as the zebra mussel (Dreissena polymorpha) can be influenced by riverine velocities and volumetric flows in invaded lake-stream ecosystems. Zebra mussels, which have a planktonic larval form (veliger), disperse rapidly downstream from a source population. Concentrations, dispersal, and body conditions of zebra mussel veligers we

Hydrogen stable isotope data for: 'Mechanisms associated with an advance in the timing of seasonal reproduction in an urban songbird'.
This dataset includes stable hydrogen isotope values of the nonexchangeable hydrogen contained in the outer most secondary feathers of dark-eyed juncos (Junco hyemalis thurberi) collected from the University of California San Diego campus in La Jolla, California in 2014. Hydrogen isotope values in feathers have become a powerful tool for inferring the breeding grounds of a wide variety of avian sp
Data Release for the influence of data characteristics on detecting wetland/stream surface-water connections in the Delmarva Peninsula, Maryland and Delaware
The datasets were generated for the Upper Choptank River Watershed in Maryland and Delaware. Depressions and the total stream network were derived from a lidar DEM collected during AprilJune 2003 (vertical accuracy root mean square error (RMSE) = 14.3 cm) and MarchApril 2006 (vertical accuracy RMSE = 18.5 cm) for Maryland (1 m resolution) and April 2007 (vertical accuracy RMSE = 18.5 cm) for Delaw
Data for estimating monthly water budgets at Panola Mountain Research Watershed, Stockbridge, Ga., water years 19862015
Data used to estimate monthly water budgets at Panola Mountain Research Watershed, Panola Mountain State Park, Stockbridge, Ga. for water years 1986-2015. Data include: (1) hourly air temperature and solar radiation data used to calculate potential evapotranspiration using the Priestly-Taylor equation; (2) unit-value streamwater stage and streamflow; (3) unit-value base flow determined from a hydr
Compilation of Data on the Middle Savannah River for the Analysis of Sub-Daily Flow Variation
The Nature Conservancy (TNC) has been working with the U.S. Fish and Wildlife Service (USFWS), the U.S Army Corps of Engineers Savannah District (USACE - Savannah) and other stakeholders on environmental flow recommendations for the Savannah River since May 2002 and have recently (2015) updated the environmental flow recommendations from 2003. Analysis of the flow data revealed a large amount of
Crystal Rock and Trib. 104 Histogram and Sewershed Data Release
This USGS data release represents the Monte Carlo modeling output for 1) the watershed histograms and 2) mean pollutant removals in the sewersheds in two study watersheds with differing spatial patterns of BMP design (traditional and LID). The data release was produced in compliance with the "open data" requirements as a way to make the scientific products associated with USGS research efforts and
Associated data for Surface-Water Supplies in the Triangle Area of North Carolina, Water Years 2014-15
These datasets contain information used to compile the report (USGS OFR 2017-XXXX). It contains water-quality data, analytical results of field blanks, and analytical results for environmental and replicate sample sets for surface-water samples collected during water years 2014 and 2015 for the Triangle Area Water Supply Monitoring Program (TAWSMP). The water-quality data contained in appendix 1 a
