Tips for safe boating:


Watch the weather. Be aware of changing water levels and conditions that would expose logs, snags or cause floating debris. Be cautious when boating in the vicinity of the dam. Do not proceed past the warning signs and buoys. Tell someone where you are going, who is with you, and how long you will be away. Avoid standing, and when changing seats, stay low and near the centerline of your boat. Be ready for trouble when a powerboat passes you in a narrow channel. Maintain a safe operating speed. Always wear approved personal flotation devices (PFD).
