Army Corps warns of lower water levels on Allegheny River
Marinas and docks could be affected by lower-than-normal water levels on the Allegheny River in Armstrong County in October, the U.S. Army Corps of Engineers said Friday.
Pool fluctuations will occur above Lock and Dam 9 at Rimer because of the removal of flashboards, steel bars and timber boards from across the crest of the dam. Lower water levels are needed for the work.
The drawdown will bring the water level about 1 foot below normal, equating to a reading of 8.5 feet on the upper pool gauge, the corps said. The water level of the upper pool is expected to be a half-foot below the crest of the dam during the work.
“Navigators are cautioned to travel within the limits of the navigation channel during the drawdown and steer clear of shallow areas,” the corps said. “Areas that are normally navigable may be temporarily unnavigable.”
Work is scheduled to be done between 6 a.m. and 6 p.m. daily until it is completed.
