This interactive geonarrative presents information on how feasible it is to develop a GIS-based hydraulic modeling tool for preliminary culvert designs for stream crossings in Massachusetts.

A method (commonly referred to as the Frimpter method) was developed in early 1980’s to estimate probable high groundwater levels across Massachusetts. The map and table on the web page linked above provide information on wells in the Massachusetts Observation-Well Network which have been used as index wells.

This interactive map displays the location of water-quality data-collection sites, the drainage area for the Merrimack River, and selected streams in the Merrimack River Basin.

View recent and historical chloride and specific conductance data for active water-quality monitoring stations on streams in Connecticut, Massachusetts, and Rhode Island.

Dashboard presenting nor’easter storm events in coastal New England in January and March 2018.

Geonarrative about flood documentation and mapping of two large storm events in coastal Massachusetts.

Locations of active wells (at least one measurement during the previous year) in the New England groundwater level network at the end of 2017. The dataset contains 104 wells with continuous water-level measurements (15-minute to hourly measurements), 182 wells with discrete water-level measurements (monthly measurements at most locations), and 95 wells with intermittent water-level measurements.

USGS installed 18 monitoring wells and 14 multilevel samplers (MLSs) at 14 locations to monitor water levels and groundwater quality beneath the Maravista neighborhood in Falmouth, Massachusetts.

The National Water Information System (NWIS) Mapper provides access to over 1.5 million sites contained in USGS Water Data for the Nation, including sites where current and historical surface-water, groundwater, springs, and atmospheric data has been collected. Users can search by site type, data type, site number, or place.
