I’m sure you don’t think of Tennessee as a coastal state, so why use Reef Balls.
The answer is simple EFH, Reef Balls have been proven to provide habitat for fish that are looking for structure. Reef Balls form a complex reef. The man made lakes behind dams are in need of structure “fish habitat” so what better way?
Reef Balls were placed in Lake Okeechobee in the 1990 since that time they have been used with success in about any ecosystem you can think of, at locations around the world.
