Water skiing is prohibited between sunset and sunrise. No person may operate water skis or similar contrivances in a careless or reckless manner so as to endanger life or property, or in a manner contrary to that designated by regulatory markers. Any person being towed behind a watercraft must wear a personal flotation device or buoyant belt. They are the Arizona Uniform State Waterway Marking System, and they alert you to danger and give directions and restrictions. It is unlawful to moor or fasten a watercraft to any regulatory marker or remove, obstruct or interfere with any regulatory marker.
Regulatory markers are can-shaped buoys colored orange and white.
The nature of the danger may be indicated, e.g. rocks, reefs, dams, construction, or snags. A diamond with a cross inside means no boats are allowed. Circles mean caution or controlled area. The nature of the restriction is indicated, e.g. speed limit, no wake, no ski, ski only. A square or rectangular shape indicates information, directions, distances, names of places, or other general information.
