State officials say regular maintenance will be a priority at Waltham's Moody Street Dam, which came online last week after seeing much of its water diverted to Mother Brook and the Neponset River so that its flashboard system could be repaired.

"We're absolutely back to normal now," said DCR commissioner Rick Sullivan. "The work we have completed should have all the ongoing leak concerns taken care of."

Sullivan stressed that the structural integrity of the dam itself was not in question. The parts replaced included the needle beams and swing arms that hold and control the dam's flashboards, which were removed to alleviate flooding during the March storms. The flashboards themselves were also replaced.

"Some of the flashboards we removed dated to 1959, when the dam was constructed," said Bill Gode-von Aesch, DCR director of flood control management. "We were surprised at a lot of the original components we found. It's not common."

Gode-von Aesch said that the maintenance schedule and records for the dam had been incomplete because of departmental restructuring during the dam's history, but that regular dam maintenance would remain a priority for the DCR.

The DCR estimated that the repairs to the dam already completed cost around $25,000. Sullivan said that the DCR was waiting on a structural engineering report to determine if any further work was necessary, such as repairs to the catwalk over the dam.

"We don't anticipate any structural work will be necessary, but we want to stay on top of things," Sullivan said. He said the DCR had no estimate on the cost for repairs to the catwalk.
