Hydrologists Hayley Lind and Patrick Scordato collect groundwater samples from the Maravista neighborhood in Falmouth, Massachusetts. 

The USGS is conducting a study to characterize groundwater and surface-water quality to better understand nutrient inputs to the coast. The initial focus of the study is on local-scale hydrologic monitoring adjacent to Academy Cove.

This streamgage is located in North Danville, Vermont, a part of the Sleepers River watershed. It is located on Pope Brook, a tributary of Sleepers River. Check out the water data for this streamgage station here.

A USGS physical scientist weighs a fiberglass tube containing a snow core on a hanging spring scale. Snow water equivalent (SWE) is calculated from the weight and volume of the snow in the tube. This measurement is being taken in Sleepers River Research Watershed in Danville, Vermont.

USGS and University of Colorado Scientist Alan Vajda, Ph.D., examines the effects of PFAS-contaminated groundwater on fish in aquaria in a mobile fish lab.

A collage of relevant keywords and photographs about stream crossing projects. Important components of stream crossing projects include flood flows, aquatic organism passage, stream crossing standards, and the hydraulic modeling tool. The photograph on the left shows a drop at the outflow of a culvert that would impede aquatic organism passage.

U.S. Geological Survey Mill River at Northampton, Massachusetts streamgage (01171500) on October 11, 2022 looking downstream. The low-flow was about 12 cubic feet per second (cfs) for a 56.2-square-mile drainage area.

A downstream view of the Green River near Colrain, Massachusetts close to the USGS streamgage (01170100). The low-flow was about 7.7 cubic feet per second (cfs) for a 41.4-square-mile drainage area.

Pearl Hill Brook at Mill Creek Drive in Ashby, Massachusetts on October 1, 2021. The drop at the outflow of the culvert would impede aquatic organism passage.

Unnamed tributary to Trapfall Brook at Harris Road in Ashby, Massachusetts, on October 1, 2021. The shallowness of water in the culvert could impede aquatic organism passage.

USGS monitors groundwater levels at sites around the Nation. The location and frequency of water-level measurements depends on the objectives of the project or program for which the data are being collected.
