All the short-term repairs at Waltham’s Moody Street dam are complete, but long-term repairs are still being examined, said the Massachusetts Department of Conservation and Recreation
All 112 flashboards and 114 needle beams were replaced at the dam, and water levels have risen back to normal, said Wendy Fox, spokeswoman for the DCR.
"None of the problems we found were structurally part of the dam. That's fine," said Wendy Fox, DCR spokeswoman. "The deterioration was in the needle beams and the release arm system, which hold the flashboards in place and control their movement."
Repairs began Wednesday To gain access to the dam, workers diverted part of the river flow into Mother Brook and the Neponset River, lowering the level of the Charles at the dam by 3 feet.
The deterioration was discovered after the dam was opened during last month's record rainstorms to control flooding along the Lake District of the Charles River.
