The Maine Office boat, "Miss Q", is parked next to the boat launch on Verona Island, ready to begin data collection on the Penobscot River. The crew was preparing to collect ADCP data (depth and velocity) as well as conductivity, temperature and depth profiles at various locations. In the background is the Penobscot Narrows Bridge and Fort Knox.

Hydrologist Charlie Culbertson holds an acoustic velocity meter under the ice covered river while standing under the covered bridge over the Ellis River at South Andover, Maine. This meter is used to collect streamflow information through the ice during the winter period.

On January 14, 2015, hydrologic technicians Jeff Kinsey (shown) and Nick Stasulis visited USGS gaging station 01030500 on the Mattawamkeag River.

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.

USGS streamflow station 01048000 (Sandy River near Mercer, Maine) is shown during an early morning site visit in October 2013.

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.

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.

This is the view upstream of the cross section.

This is the view downstream of the cross section.

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.

On October 6, 2011 USGS staff were visiting their streamflow station at the outlet of Bass Harbor Marsh and snapped this photo of a rainbow over the gage house.

The USGS has been monitoring the Kennebunk River near Kennebunk, Maine since June 2008 and the peak discharge for the period of record occurred in February 2010.

As the Little Androscoggin River flows through western Maine it eventually reaches Snow Falls, a 25 ft cascading waterfall in the town of West Paris.
