Data
The New England Water Science Center operates over 500 real-time data collection sites throughout the six New England states. The sites collect surface-water, groundwater, water-quality, and precipitation data. Much of our real-time data is publicly available through NWIS. Additional data releases are also available on the page below.

MODFLOW-NWT Upgrade and Preliminary-Assessment of a Groundwater-Flow Model of the Seacoast Bedrock Aquifer, New Hampshire MODFLOW-NWT Upgrade and Preliminary-Assessment of a Groundwater-Flow Model of the Seacoast Bedrock Aquifer, New Hampshire
Improvements to an existing regional groundwater-flow model of a 160-square mile area of coastal New Hampshire (https://doi.org/10.3133/sir20085222), incorporating MODFLOW-NWT and by more accurately representing stream characteristics, were presented at the MODFLOW and More 2017 conference in an example simulating approximate changes in water use. The groundwater-flow model developed for...
Nitrogen Concentrations and Loads and Seasonal Nitrogen Loads in Selected Long Island Sound Tributaries, Water Years 1995-2021 (ver. 1.1, February 2024) Nitrogen Concentrations and Loads and Seasonal Nitrogen Loads in Selected Long Island Sound Tributaries, Water Years 1995-2021 (ver. 1.1, February 2024)
This U.S. Geological Survey (USGS) data release presents tabular data on nitrogen concentrations and loads for multiple nitrogen species, and river discharge data used in the analysis of data collected from October 1994 to September 2021.

Software for the program code AFCE (Aqueous-Flow-Concentration-Estimator) for estimation of ambient groundwater flow in bedrock open boreholes using concentrations of chlorinated volatile organic compounds from coupled straddle packer and passive sampling Software for the program code AFCE (Aqueous-Flow-Concentration-Estimator) for estimation of ambient groundwater flow in bedrock open boreholes using concentrations of chlorinated volatile organic compounds from coupled straddle packer and passive sampling
Software program code for the AFCE (Aqueous Flow Concentration Estimator) that is used to estimate inflow of groundwater contaminants to a water column of an open borehole in a fractured-rock aquifer. It is particularly useful program for assessing ambient flow in low permeability open boreholes, which have no detectable flow as measured with conventional borehole flowmeter tools. The...
Data on Models to Describe Groundwater Levels and Stream Stage near the Herring River, Wellfleet, Cape Cod, Massachusetts, 2017-2022 Data on Models to Describe Groundwater Levels and Stream Stage near the Herring River, Wellfleet, Cape Cod, Massachusetts, 2017-2022
Groundwater and estuary water levels near Mill Creek and the Herring River in Wellfleet, Massachusetts, were measured from June 2017 to August 2022. The data contained in these datasets consist of tables of updated statistics provided in the original work by Mullaney and others (2020, Appendix 2) and associated data release by Mullaney and Barclay (2020). The data include summary tables...

This data release includes water-quality data collected at up to thirteen locations along the Merrimack River and Merrimack River Estuary in Massachusetts. In this study, conducted by the U.S. Geological Survey (USGS) in cooperation with the Massachusetts Department of Environmental Protection, discrete samples were collected, and continuous monitoring was completed from June to...
Data for Characterizing Changes in the 1-percent Annual Exceedance Probability Streamflows for Climate Change Scenarios in the Housatonic River Watershed, Massachusetts, Connecticut, and New York Data for Characterizing Changes in the 1-percent Annual Exceedance Probability Streamflows for Climate Change Scenarios in the Housatonic River Watershed, Massachusetts, Connecticut, and New York
The U.S. Geological Survey in cooperation with the Federal Emergency Management Agency has conducted a study to evaluate potential changes to1-percent annual exceedance probability (AEP) streamflows. The study was conducted using the Precipitation Runoff Modeling System (PRMS). Climate inputs to the model of temperature and precipitation were scaled to anticipated changes that could...
Hydroacoustic Data to Support Embayment Monitoring in Long Island Sound, Mystic and Norwalk Embayments, Connecticut, 2021-2022 Hydroacoustic Data to Support Embayment Monitoring in Long Island Sound, Mystic and Norwalk Embayments, Connecticut, 2021-2022
This data release includes hydroacoustic data for the 2021 to 2022 water years at four stations. These stations are part of a discrete and continuous monitoring project in embayments on Long Island Sound to support nutrient management activities in Connecticut. The data were collected by the U.S Geological Survey (USGS) in cooperation with the Connecticut Department of Energy and...
MODFLOW-2000 and Management-Optimization Models Used to Evaluate Alternative Groundwater-Withdrawal Scenarios on Water Levels in Kingsbury Pond, Upper Charles River Basin, Eastern Massachusetts MODFLOW-2000 and Management-Optimization Models Used to Evaluate Alternative Groundwater-Withdrawal Scenarios on Water Levels in Kingsbury Pond, Upper Charles River Basin, Eastern Massachusetts
An existing, three-dimensional, transient groundwater-flow model of the Upper Charles River Basin, eastern Massachusetts, was modified to evaluate alternative groundwater-withdrawal scenarios on water levels in Kingsbury Pond. The pond is hydraulically connected to the groundwater-flow system, and water levels in the pond fluctuate in response to recharge to the aquifer from...
