Geospatial Bathymetry Dataset and Elevation-Area-Capacity Table for Ashokan 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 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
