The city, which saw up to 6 inches of rainfall in 24 hours, activated its Emergency Operations Center on Thursday night to monitor the situation at the Robin Hood Park Dam. The fire department pumped water from that area into storm drains. Nearby residents were told they might be affected if the storm waters exceeded the dam's capacity.
By 11:30 p.m., the water levels subsided and the dam was deemed safe.
The man-made dam was built in the late 1800s. In 2008, the state said part of it needed to be redesigned and construction work to strengthen it was started this year.
