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

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).

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.

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.

This photograph shows Lowe's Bridge off ME-15 in Guilford, Maine, spanning the Piscataquis River. USGS gaging station 01031500 is located on the downstream side of the bridge.

This ADCP sends an acoustic pulse into the water to measure the speed of the water, the depth of the river and to measure how far it's moved across the river. With this information, it can compute discharge.

A manned boat is used to ferry the ADCP back and forth across the river. The velocities at this section were quite slow, and the line across the river allowed better control than driving the small boat.

This is the view upstream of the cross section.

This is the view downstream of the cross section.

This is the cross section where the measurement was made and the line we strung across the river, marked with flagging for visibility. In slow velocities, the line helps control the speed of the boat as it is moved across the channel.
