Keep a sharp lookout for debris. Lake levels vary. Heavy rainfall upstream may move debris into the lake, even if it hasn't rained in the immediate area. Some lake maps are available from the LCRA, and others are commercially available. Always stop the motor when near someone in the water.
Water is usually deeper on the cliff side.
The shallow side usually gradually slopes down to the water. When maneuvering around a point of land, allow extra clearance between the boat and shoreline. Points of land can extend a considerable distance below the water's surface. Operational rules and required safety equipment for PWC are the same as those for any other powerboat. A PWC may not be operated within 50 feet of anything, including another PWC, except at a no-wake speed.
