Model climate scenario output for the Blackstone, Pawcatuck, and Ipswich river basins, Massachusetts, 2036-2065 change from 1975-2004, Representative Concentration Pathways 4.5 and 8.5

This data release provides a set of Hydrological Simulation Program--Fortran (HSPF) model files representing 5 EPA-selected future climate change scenarios for each of three river basins: Blackstone in Massachusetts and Rhode Island, Pawcatuck in Rhode Island, and Ispwich in Massachusetts. Output from these models are intended for use as input to EPA Watershed Management Optimization Support...

Thirty- and ninety-year data sets of streamflow, groundwater recharge, and snowfall simulating potential hydrologic response to climate change in the 21st century in New Hampshire

The U.S. Geological Survey (USGS), in cooperation with the New Hampshire Department of Environmental Services (NHDES) and the Department of Health and Human Services (NHDHHS), has developed data to assess the effects of short- and long-term climate change on hydrology in New Hampshire. A USGS Scientific Investigations Report (SIR) documents the datasets developed by the USGS. The data...

WellYield_GIS_NashobaTerrane

This data set is a point data layer representing well yield at 7,287 bedrock wells in the Nashoba Terrane in central and eastern Massachusetts. The data were compiled from databases of the Massachusetts Department of Environmental Protection and U.S. Geological Survey. The data are described and interpreted in U.S. Geological Survey Scientific Investigations Report 2012-5155 by DeSimone and...

Estimates of annual and daily concentration and flux of nutrients, chloride, and total suspended solids in tributaries of Lake Champlain, 1990 through 2014

This USGS data release presents tabular data of daily and annual (for the 9-month period March 1 through November 30) estimates of concentrations and fluxes of total and dissolved phosphorus, total nitrogen, chloride, and total suspended solids for 18 monitored tributaries of Lake Champlain. Daily estimates generally cover the period March 1990 through November 2014 and annual estimates 1990...

Streamflow and total phosphorus and orthophosphate data for samples collected in and near the Assabet River, Massachusetts, October 2008 through April 2014

Streamflow and phosphorus concentrations were monitored in the Assabet River in central Massachusetts in order to evaluate concentrations and loads in the river before, during, and after changes in the amount of total phosphorus that was discharged to the river from three wastewater-treatment plants. At four locations the U.S. Geological Survey collected weekly flow-proportional, composite...
