Ray Roberts Lake has zebra mussels, so clean, drain, and dry
Ray Roberts Lake is infested with zebra mussels. The mussels and their tiny larvae can ride on boats, trailers, gear, or trapped water. They damage motors and water intakes and harm native species.
Before leaving or approaching public fresh water, drain livewells, bilges, motors, bait buckets, and other onboard containers. Remove attached harmful plants. Clean off mud and debris, then let everything dry for at least a week when possible. If a boat has been stored in Ray Roberts Lake, call TPWD at 512-389-4848 before moving it; the boat may need decontamination.
