New England Water Science Center

Home

The New England Water Science Center partners with many federal, state, and private entities to monitor and study the region’s water resources. We conduct hydrologic investigations and research projects.

We offer information on streamflow, water quality, groundwater and water-use data for Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont.

USGS measures discharge at the Ohio River at Olmsted Lock and Dam
March 7, 2018

Crews from the U.S. Geological Survey have been in the field for weeks measuring flooding in the Midwest and in the Mississippi River watershed, and more recently flooding and storm tides on the Northern Atlantic coast, as higher temperatures, heavy rain, snowmelt and nor’easters affected numerous states. 

Nor'easter
March 1, 2018

USGS field crews are deploying storm-tide and wave sensors today from Maine to Delaware to track and study a Nor’easter forecasted to begin tomorrow.

Measuring high water mark - blizzard of January 2018 in New England
January 15, 2018

Significant flooding along the coast of Massachusetts occurred Thursday, January 4, 2018, caused by a powerful blizzard.  Peak storm surge of approximately 3.00 feet occurred at the astro high tide; and, according to the National Weather Service, is the highest since records began at the Boston tide station in 1921.

Streamflow, water quality, and constituent loads and yields, Scituate Reservoir Drainage Area, Rhode Island, water year 2015

Streamflow and concentrations of sodium and chloride estimated from records of specific conductance were used to calculate loads of sodium and chloride during water year (WY) 2015 (October 1, 2014, through September 30, 2015) for tributaries to the Scituate Reservoir, Rhode Island. Streamflow and water-quality data used in the study were collected...

Estimation of unregulated monthly, annual, and peak streamflows in Forest City Stream and lake levels in East Grand Lake, United States-Canada border between Maine and New Brunswick

The U.S. Geological Survey, in cooperation with the International Joint Commission, compiled historical data on regulated streamflows and lake levels and estimated unregulated streamflows and lake levels on Forest City Stream at Forest City, Maine, and East Grand Lake on the United States-Canada border between Maine and New Brunswick to study the...

Nitrogen concentrations and loads for the Connecticut River at Middle Haddam, Connecticut, computed with the use of autosampling and continuous measurements of water quality for water years 2009 to 2014

The daily and annual loads of nitrate plus nitrite and total nitrogen for the Connecticut River at Middle Haddam, Connecticut, were determined for water years 2009 to 2014. The analysis was done with a combination of methods, which included a predefined rating curve method for nitrate plus nitrite and total nitrogen for water years 2009 to 2011...
