COLUMBUS, GA (WTVM) - A portion of the Riverwalk in Columbus is closed as crews gear up to build a new dam.
It's the first step towards seeing the whitewater rafting course come alive along the Chattahoochee River.
News Leader 9's Roslyn Giles was at North Highlands Dam on Monday where construction will soon start.
We're told this new dam is necessary to keep the same water elevation upstream at the North Highlands Dam operated by Georgia Power.
Their crews will put in the new dam, called a weir, which smaller than the City Mills Dam located downstream.
That's why you see orange signs indicating the Riverwalk is closed at North Highlands Dam near 35th Street in Bibb City.
Pedestrians can take a detour along the Riverwalk from South Gordon Boulevard on to 1st Avenue towards Bibb City just north of the dam.
"Once the city mill's dam is removed, the water levels will drop and we have to put this weir in to maintain the elevation so the units will continue to flow without damage," said Arnold Lindsay, project manager with Georgia Power.
Lindsay says work will begin in January on the weir after the City Mills Dam is breached. Whitewater rafting is expected to be in place by the end of next year.
The 2.5-mile long whitewater course has a price tag of $23 million.
