They said that there was a potential for a large loss of property and life downstream, in the towns of Leverett and Montague,[2] if the dam should fail.

Many local residents, particularly in Leverett and Montague, were frustrated with the governor's decision.

Despite the gubernatorial veto, funding was eventually obtained and construction began at the dam in the fall of 2008.
