Sudbury Dam located in Southborough Massachusetts was built in 1894. A storehouse was built in 1900.

A buoy instrumented to collect meteorological observations is recovered off Fire Island, NY in 2014.  The data collected is part of a study of the coastal processes that mobilize and transport sediment in the region

On April 10, 2014 hydrologic technicians Nick Stasulis and Anthony Underwood visited the USGS gaging station on Grand Lake Stream at Grand Lake Stream, Maine. The cableway was used to make a discharge measurement with an acoustic Doppler current profiler (ADCP).

Spring in Maine introduces significant challenges for hydrographers when it comes to accessing remote stations. In this photo, hydrologic technician Anthony Underwood is prepared to visit the USGS gaging station on Libby Brook near Northfield, Maine.

On April 9, 2014 a visit to the USGS gaging station on Libby Brook near Northfield, Maine showed that while runoff had caused a large rise in the small brook, there still remained a significant snowpack in the area.
