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.

Data on Tidally Filtered Groundwater and Surface-Water Levels, and Climatological Data Near Mill Creek and the Herring River, Cape Cod, Wellfleet, Massachusetts, 2017-2018

Groundwater and estuary water levels near Mill Creek, and the Herring River in Wellfleet Massachusetts were measured from June 2017 to June 14, 2018. Water-level data have been filtered to remove the effects of the daily tides. The mean daily value of the tidally filtered 15 minute water-level data is presented. The data also include a composite data set of daily precipitation values, as well as d

Simulated 25-year potential annual recharge datasets for Maine, 1991-2015

This set of data includes four potential annual recharge grids for the State of Maine that were simulated using the Maine Soil-Water-Balance model for 1991 through 2015. The files include a grid representing the uncertainty in the potential recharge and a grid showing the annual average precipitation from the climate dataset that the simulation is based on. A 25-year simulation of potential rechar

Snow Depth and Snow Water Equivalents at Sleepers River Research Watershed, Danville, Vermont

Snow depth and snow water equivalent (SWE) measurements have been made at Sleepers River Research Watershed starting in 1960. Initial snowpack measurements were made by the Agricultural Research Service joined by the National Weather Service in 1966. Cold Regions Research and Engineering Laboratory started measuring the snowpack in 1979, followed by the U.S. Geological Survey from 1993 to the pres

Lithostratigrapic, Geophysical, and Hydrogeologic Observations from a Deep Boring in Glacial Sediments on Davis Neck near Nantucket Sound, East Falmouth, Western Cape Cod, Massachusetts

Lithostratigraphic and hydrogeologic observations for the unconfined aquifer of western Cape Cod are limited near coastal groundwater-discharge areas. In spring 2015, a 310-foot-deep boring was drilled and a well was installed to 100 feet below land surface to facilitate detailed study of aquifer characteristics along the southern coast of Cape Cod. Characteristics of interest included the depth a

Data Release for Lake Shadow Seepage Calculations from Ashumet Pond, Cape Cod, MA, 2016 - 2018

Hydrologic data were collected in the nearshore lake-bottom sediments of five lakes on western Cape Cod, Massachusetts: Ashumet (Falmouth), Long (Centerville), Santuit (Mashpee), Shubael (Barnstable), and Snake (Sandwich) Ponds. Water budgets of flow-through glacial kettle lakes are commonly dominated by groundwater flow into and surface-water seepage out of the lake, and inputs and losses from pr

Drought Streamflow Probabilities in Northeast Region

Maximum likelihood logistic regression (MLLR) is used to estimate drought probabilities for selected Northeast rivers and streams. Winter streamflows are used to estimate the chance of hydrologic drought during summer months. This application allows the display and query of these drought streamflow probabilities for Northeastern streams.

Trends in 7-day-low streamflows at 174 USGS streamflow gages in the Chesapeake Bay watershed, Mid-Atlantic U.S.

This data set contains U.S. Geological Survey (USGS) streamgage identification numbers, begin and end years of the periods of streamflow record tested, Sen slope trends in the annual minimum 7-day streamflow for the period of record tested, the p-values (significance) of the trends, and the trend Sen slopes standardized by the standard deviations of the residual errors defined as the difference be
