The Dow Brook Reservoir and Dam are located along High Street/Route 1A adjacent to the Ipswich Utilities Complex. They were originally constructed in 1894. Seepage on Dow Brook Dam was observed by Water Department staff on the downstream slope of the dam in early April 2018. The current status of the dam is stable, but unsafe. The Water Department is working closely with its engineering consultant and the Massachusetts Office of Dam Safety to complete investigations and repairs, and bring the dam back in to compliance with Massachusetts Dam Safety Regulations.
The Water Department has closed Dow Brook Dam until further notice. Area trails will remain open and fishing is allowed along the banks of the reservoir, but not from the dam.
