Nicholas Stasulis
Nicholas Stasulis is a Supervisory Physical Scientist 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). Starting in 2016, Nick supervised staff in the Maine Office of the New England Water Science Center, with a focus on streamflow and groundwater monitoring. Beginning in 2024, Nick oversees the Monitoring Operations Section for the New England Water Science Center. 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.

Federal Priority Streamgages (FPS)
Federal Priority Streamgages (FPS) are automated stations that monitor water conditions in streams and rivers throughout the country. Originally established in 1999, these are important for meeting specific long-term needs of the Nation. The FPS Network was recently re-prioritized which resulted in size of the network increasing to nearly 12,400 locations.
Water Resources Inventory and Assessment at Katahdin Woods and Waters National Monument
The U.S. Geological Survey (USGS) New England Water Science Center, in cooperation with the National Park Service, is compiling and evaluating all known water resources, and documented infrastructure associated with these resources, within the Katahdin Woods and Waters National Monument and contributing associated watersheds.
Remembering Tropical Storm Irene in New England
On August 28, 2011 Tropical Storm Irene made landfall in New England, leading to coastal storm surge, significant riverine flooding, sediment transport to Long Island Sound, and major infrastructure damage and destruction. Ten years later, the USGS New England Water Science Center looks back at Irene, the data collected by our Center during the event, the response by our employees before, during...
