Data

Continuous and discrete surface-water, groundwater, and water-quality data are collected to provide long-term hydrologic records critical to investigating hydrology, modeling climate-change, evaluating natural and anthropogenic changes in the hydrologic regime, and providing information on water availability to water managers.

Geospatial Bathymetry Dataset and Elevation-Area-Capacity Table for Rondout Reservoir, 2013 to 2014

From 2013 to 2015, bathymetric surveys of New York Citys six West of Hudson reservoirs (Ashokan, Cannonsville, Neversink, Pepacton, Rondout, and Schoharie) were performed to provide updated capacity tables and bathymetric maps. Depths were surveyed with a single-beam echo sounder and real-time kinematic global positioning system (RTK-GPS) along planned transects at predetermined intervals for each

Hormone, pesticide, pharmaceutical and other organic compound data for select water and bed sediment samples collected in Chesapeake Bay watershed in parts of Maryland, Pennsylvania, Virginia, and West Virginia, 2006-2014

These data represent water and bed sediment samples analyzed for a variety of organic compounds. The samples were collected in streams and rivers in the Chesapeake Bay watershed from 2006-2014. Water samples were collected from 61 sites and analyzed for hormones (SH2434 method; Tables 1A and 1B), pharmaceuticals (SH2080 method; Tables 2A and 2B), wastewater indicators (SH1433 method; Tables 3A and

Data for effects of watershed and in-stream liming on macroinvertebrate communities in acidified tributaries to an Adirondack lake

In 2012, a program was initiated using in-stream and aerial (whole-watershed) liming to improve water quality and Brook Trout (Salvelinus fontinalis) recruitment in three acidified tributaries of a high-elevation Adirondack lake in New York State. Concurrently, macroinvertebrates were sampled annually between 2013 and 2016 at 3 treated and 3 untreated reference sites to assess the effects of each

Data for relationships between fish assemblages and acid-base chemistry in streams of the Great Smoky Mountains National Park, 1993-2014

Fish community richness, density, and biomass for entire communities, Brook Trout, Rainbow Trout, and minnows, including site characteristics, and water chemistry (acid neutralizing capacity, pH, nitrate, sulfate, ammonia, calcium, and total aluminum) collected at least once and as many as 13 times at each of 52 stream sites during the same years that fish were inventoried, Great Smoky Mountains N

Northeastern Hydrologic Benchmark Network (HBN) Soil Chemistry and Catskill Mountain Water-Quality Data

This data product contains soil chemistry data from 4 locations. Two of the locations were located in the Neversink River watershed near Claryville, NY (01435000) in the Catskill Mountains of New York (Fall Brook and Winnisook Creek), 1 of the locations was the Young Womans Creek watershed near Renovo, PA (01545600) and the last site was the Wild River watershed at Gilead, Maine (01054200). Soil c

Adirondack Forest Soil Chemistry 1997-2014

This dataset contains measurements of chemical concentrations of forest soil samples and associated site measurements collected in the Adirondack Ecoregion of New York State. Data are presented in four groups (tabs) in an Microsoft EXCEL 2013 spreadsheet (and comma-delimited CSV files): (1) Adirondack Sugar Maple Project (ASM), (2) Buck Creek North Watershed, (3) Buck Creek South Watershed, and (4

Adirondack New York vegetation data, 2000-2015

This dataset contains field measurements of vegetation from the (1) Adirondack Sugar Maple Project (ASM), and (2) Buck Creek North and Buck Creek South Watersheds. The ASM data, collected in 2009 in 20 Adirondack watersheds (2 or 3 0.10 ha plots per watershed), are comprised of general plot characteristics, tree species identification and diameter at breast height (DBH) for all trees greater than

Data for Assessing the Status of Sediment Toxicity and Macroinvertebrate Communities in the Eighteenmile Creek Area of Concern

The data include the sample collection information and results from 10-day exposures of two test species, Chironomus dilutus and Hyalella azteca to sediments from Eighteenmile Creek and Oak Orchard Creek, NY. The following endpoints were measured for each species following the 10-day exposure: percentage of organisms surviving (hereafter survival) and average ash-free dry weight of the surviving o

Surface-water data for New York

Real-time, daily, peak-flow, field measurements, and statistics of current and historical data that describe stream levels, streamflow (discharge), reservoir and lake levels, surface-water quality, and rainfall in New York. Surface-water data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.
