Scott Bendtson, a hydrologic technician with the Maine Office of the New England Water Science Center, is seen here making a discharge measurement through the ice on the St. John River at Ninemile Bridge, USGS station number 01010000.

Nick Stasulis, a hydrologic technician with the Maine Office of the New England Water Science Center, is seen here making a wading discharge measurement on the East Branch Wesserunsett Stream near Athens, USGS station number 01048220.

An ice jam on the East Branch Wesserunsett Stream in Athens, Maine in January 2014 left 3-5 ft ice walls on the riverbanks. On a January 21, 2014 site visit Nick Stasulis and Charlie Culbertson chisled away some of the ice wall so a discharge measurement could be made.
