The Sweetwater County Sheriff's Department is warning boaters and water skiers to be on the lookout for unusual debris over the next few days.

Spokesman Dick Blust says deputies patrolling the gorge last weekend discovered and towed what is believed to be en old bridge or dock piling. He says the structure was 20 feet long and about two feet thick. Even though that structure was removed, Blust says authorities are concerned other floating debris may have found it's way into the lake. and could pose a safety hazard.

He says a boat hitting such debris at a high rate of speed could be disastrous. The warning is in effect through the upcoming 4th of July weekend.
