From Appalachian Power: Crews have completed repairs to a floating boat barrier that flipped underwater near the Smith Mountain Lake Dam last month. The barrier’s top section was knocked over by a combination of ice buildup, snow and wind and was discovered Feb. 22.Because vertical sections of the barrier were underwater, the structure was harder to see by boaters on the lake surface. However, three companion lighted buoys remained operational and were visible at night.A contractor for Appalachian repaired and righted the 1,000-ft. barrier earlier this week. The structure runs between the Bedford and Pittsylvania County slopes of the Smith Mountain gap where the dam is located. It is between navigational marker R1 and the dam and was designed to keep boats away from dangerous power generation areas. Appalachian had ordered a new boat barrier and warning system for the location before the winter damage occurred. The new structure is expected to be in place by fall 2015.
