smith mountain lakeA special type of fish is taking a bite out of an aquatic plant problem in Smith Mountain Lake. Hydrilla became a concern after being discovered at the lake in 2007. The invasive vegetation has a history of growing out of control; and left unchecked, it’s been known to completely take over coves to a point that they can make any type of water recreation impossible, but now the pesky weed is virtually non-existent thanks to sterile grass carp that were stocked this year. According to the Smith Mountain Eagle, the carp have been devouring every sign of the dreaded vegetation since being placed there in April.
