Kelly Middle School was made available as an Emergency Shelter for people for most of the day.
By Wednesday evening, the evacuation order was lifted after the state determined the dam was not in imminent danger of failing.
People were allowed to return to their homes Wednesday evening.
The Norwich Fire Department and officials from Bozrah will monitor the dam overnight. They urged residents to remain vigilant and said the evacuation order could be reinstated if the condition of the dam deteriorates.
Gov. Ned Lamont said the Fitchville Pond Dam, which is privately owned, was built in the 1840s, and it was rebuilt in the 1980s.

Norwich Public Utilities also took a substation offline because of the threat, disrupting power to thousands.
