Wareham police and fire were unsuccessful in their attempts to locate the man, so additional assistance was requested including the Wareham Department of Natural Resources and Environmental Police. The Plymouth County Technical Rescue Team (PCTRT) was also activated and multiple departments and members of PCTRT responded to the scene, including the regional dive team. Emergency personnel performed search operations in difficult conditions until 11:45 p.m. Sunday when the search was postponed due to time and weather conditions. "The water is murky. Stumps, trees and other objects are in there, so there's a lot of hazards they're trying to get around," Wareham Assistant Fire Chief Patrick Haskell said. "Plus there's ice -- trying to get ice moved around under the ice using divers, sonar."
