- Description:
Effective 21 October, 2019, a BioAcoustic Fish Fence (BAFF) has been installed by the USFWS at Barkley Lock to determine its suitability in deterring further invasion of Asian Carp into the Cumberland River system via Barkley Lock. This operational test is anticipated to last for approximately 3 years.
Upon approaching the lock, the following may be observed:
Flashing lights at night (particularly when water levels are low). These rate of
flash is slow and is below the threshold for anyone with photosensitive epilepsy
A line of bubbles will run the width of the channel from the main guide wall to the
opposing bullnose. Small craft may feel a vibration from the bubble curtain.
The sound barrier itself may be heard through the hull of the vessel as well as on
deck. This noise level does not pose a hazard. - Lat / Lon: N 37° 01.414' / W 088° 13.589'
