Nicholas Stasulis
Nicholas Stasulis is a Supervisory Hydrologic Technician in the New England Water Science Center.
Nick is experienced in collection and publication of hydrologic data; the use of acoustics for measurement of streamflow in open-water and ice conditions; collaborating with partners and cooperators to develop proposals to meet their science needs; and training staff on USGS policies/methodologies for collection of hydrologic data.
Nick began his USGS career as a student with the Maine Water Science Center while attending the University of Maine. After graduation, Nick worked in the Maine Data Program, building an expertise in the collection and publication of streamflow and groundwater data. In addition, Nick took a particular interest in the use of hydroacoustics for measurement of velocity and streamflow. This interest led to opportunities to test new acoustic Doppler current profilers (ADCPs) for the USGS, teach national training courses on the subject, and serve as a member of the USGS Hydroacoustics Work Group (HaWG). Since 2016, Nick has supervised staff in the Maine Office of the New England Water Science Center, with a focus on streamflow and groundwater monitoring. Nick also serves on the IJC International St. Croix River Watershed Board, and as co-chair of Maine's Drought Task Force and River Flow Advisory Commission.

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.

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.

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.

Hadlock Brook, in Acadia National Park, is a small watershed that was monitored by the USGS from 1999 to 2006. The Hadlock Falls is a popular spot for a break on one of the many scenic trails through the park. The USGS gaging station was approximately 100 ft above the falls.

In February 2005 a visit to a USGS station on Libby Brook near Northfield, Maine revealed a gap between the water level and a layer of ice above. Cold temperatures after a rain event caused the ice layer to form and as water levels dropped the ice layer remained.
