This dataset contains watershed means of estimated percent impervious surfaces for three time periods: 1992, 2002, and 2012. Estimates are based on coefficients derived from comparing land use of the 2012 NAWQA Wall-to-wall Anthropogenic Land-use Trends (NWALT) product to the 2011 National Land Cover Database (NLCD) imperviousness, then applying those coefficients to previous years (1974-2002) of the NWALT dataset.

This metadata record documents 11 comma delimited tables representing the amount of reported best management practice (BMP) implementation for the years from 1985 to 2014 at three geographic scales: county or land-river modeling segment, River Input Monitoring (RIM) station drainage areas, and the entire Chesapeake Bay Watershed (CBWS). Data originated from the Chesapeake Bay Watershed jurisdictions including Maryland, Pennsylvania, Virginia, Delaware, New York, West Virginia, and the District of Columbia. Data were reported to the Chesapeake Bay Program for an annual review of progress toward meeting nitrogen, phosphorus, and sediment reduction goals.
The U.S. Geological Survey (USGS) is providing a polygon feature class delineating the extent of Glacial Lake Great Bend within the Binghamton East 1:24,000 quadrangle of south-central Broome County, New York, 2020. The shapefile was created and intended for use with geographic information system (GIS) software. A companion report, USGS Scientific Investigations Report 2021-5026 (Van Hoesen and others, 2021; https://doi.org/10.3133/sir20215026) further describes data collection and map preparation.

Geologic structure and isopach maps were constructed by interpreting over 19,890 trackline kilometers of co-located multichannel boomer, sparker and chirp seismic reflection profiles from the continental shelf of the Delmarva Peninsula, including Maryland and Virginia state waters. In this region, Brothers and others (2020) interpret 12 seismic units and 11 regional unconformities. They interpret the infilled channels as Late Tertiary and Quaternary courses of the Susquehanna, Potomac, Rappahannock, York and James Rivers and tributaries, in addition to a broad drainage system. These regional unconformities form a composite unconformity interpreted as the Quaternary-Tertiary (Q-T) unconformity. A depth to Tertiary...

This dataset contains values of normal reservoir storage in units of acre-feet per km2, for three time periods: 1992, 2002, and 2012. Values are derived from a slightly-modified version of the National Inventory of Dams (NID) 2013 dataset, for which approximately 10% of records had the dam completion date estimated.

Data are included for laboratory studies evaluating the thermal biology of several freshwater mussel species and their host fish including dwarf wedgemussel (Alasmidonta heterodon), brook floater (Alasmidonta varicosa), creeper (Strophitus undulatus), eastern elliptio mussel (Elliptio complanata), tesselated darter (Etheostoma olmstedi), and slimy sculpin (Cottus cognatus). Thermal endpoints include critical thermal maximum, temperature preference, oxygen consumption rates, and clearance rates of organisms acclimated to a range of temperature treatments.

This metadata record documents 3 sets of comma delimited tables representing the amount of reported best management practice (BMP) implementation within the Chesapeake Bay watershed as well as output data from scenarios of the Chesapeake Bay Program Phase 5.3.2 Watershed Model. The scenario data were used to estimate the effects of BMPs on water quality. The data are organized by three themes (child items below); 1) BMP implementation and definitions, 2) isolation scenarios, and 3) "Progress" and "No Action" scenarios.
This dataset contains values of soils, climate, hydrologic, topographic, and other geographic characteristics such as drainage area. These are considered "static" characteristics, which do not change over the time period of this study.

Winter-spring nitrogen loads as measured at the Susquehanna River at Conowingo Maryland and Potomac River at Washington, D.C. have been determined to be an effective indicator of summer anoxic and hypoxic volume in Chesapeake Bay. The U.S. Geological Survey (USGS) provides an estimate of winter-spring nitrogen loadings to support an annual forecast of summer Chesapeake Bay conditions. The specific period of estimation includes the months of January through May. This forecast is coordinated through an established relationship with the National Oceanic and Atmospheric Administration (NOAA), University of Maryland Center for Estuarine Science (UMCES) and Maryland's Department of Natural Resources. The results presented...

These data represent surface 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 2012-2018. Sites were located in Maryland, Pennsylvania, and West Virginia. Surface water samples were collected from 25 sites and analyzed for estrogenicity and an extensive suite of organic contaminants including hormones, pharmaceuticals, wastewater indicators, pesticides, phytoestrogens, and mycotoxins. Bed sediment samples were collected from 20 sites and analyzed for a suite of organic contaminants including hormones, wastewater indicators, pesticides, and organohalogens. Bed sediment was also analyzed for total organic...

This metadata record documents 2 comma delimited tables representing output from the Chesapeake Bay Program Phase 5.3.2 Watershed Model. The effect of best management practices (BMP) in 2014 in the Chesapeake Bay Watershed (CBWS) is estimated through a series of model scenarios that isolate the effect of individual BMPs. Data include a table describing the series of isolation scenarios and the summarized output of all scenarios. Scenario output include the estimated nitrogen, phosphorus, and sediment mass reductions for each BMP. Analysis of BMP implementation over time can provide insight to water quality restoration progress.
This metadata report documents a shapefile of watershed boundaries for 84 selected United States Geological Survey (USGS) water quality stations that are part of the Chesapeake Bay non-tidal network (NTN).

Data are included for two types of field surveys conducted for freshwater mussels throughout the Susquehanna River Basin (and one site in the Potomac River Basin) in the Mid-Atlantic region of the United States from 2008-2010. Timed search (qualitative) surveys were conducted in consecutive ~200 meter sections of river (at least 8 in each stream). The number of mussels of each species and associated search time were recorded for each survey section to determine a catch per unit effort (CPUE; number of individuals found per person hour). Within qualitatively surveyed areas, one ~200 meter section of stream was selected in which to conduct quantitative surveys to estimate mussel abundance, assess presence of juvenile...
