Several homes were evacuated and power shut off as the high waters threatened residences there.
The US Army Corps of Engineers and the National Oceanic and Atmospheric Administration (NOAA) confirmed a sieche effect had caused a sudden surge in water levels which at one point changed levels in the area to from a drop of – 14 inches to an increase of +51 inches.
A seiche is a naturally occurring phenomenon that when combined with dramatic changes in atmospheric pressure or a sudden drop in the wind speed produces a water surge.
Residents were returned to their homes at approximately 7:15 p.m.
No injuries were reported.
