Thursday night's torrential rain saw the dam at College Lake in danger of breaking which would have caused massive flooding in Lynchburg.
Measures were taken by the City of Lynchburg to relieve pressure on the dam.
"For the first time in probably 50 years or more, the emergency sluiceway at the bottom of College Lake dam has been opened and the lake is slowly starting to empty. This is being done to relieve pressure on the dam which was damaged during Thursday night's torrential rains and to make it easier to repair the structure."
The estimate right now is 6-8 weeks but that may change as they get further into the project.
