Under the Inland Navigation Rules, a red buoy typically indicates the location of a safe water mark or a channel marker. It is part of the IALA (International Association of Lighthouse Authorities) system, where red buoys are used to indicate the port side of a channel when entering from the sea. In inland waters, red buoys also serve to mark navigational hazards or indicate the edge of a channel. Boaters are expected to keep these buoys on their port (left) side when navigating upstream.
Do not pass between the buoy and the shore

A diamond on a buoy means danger or warning. If the diamond on the regulatory buoy is open, it's a warning. It may indicate the presence of a rock, dam, wreck or other danger. Usually, the danger present is indicated under the diamond. If the diamond on the regulatory buoy is crossed, it means you should not enter. It may be a swimming area (which would be a "do not enter" area for boats), rapids, or some other danger.

In New Hampshire, a white buoy with a black top typically signifies a restriction against swimming in that area. These buoys are often used to mark off zones for safety reasons, such as areas with hazardous conditions, underwater obstructions, or designated swimming zones. Always check local regulations and signage for specific rules regarding buoy meanings.
A yellow crossed diamond buoy indicates a designated area where activities such as swimming, fishing, or boating are prohibited. This buoy typically serves as a warning to mariners and recreational users to keep clear of the area for safety reasons. It's important to pay attention to such markers to avoid potential hazards. Always check local regulations for specific meanings and rules associated with buoys in the area.
A white buoy with orange bands and an orange diamond is a hazard buoy. Watch out for shoals, rocks, fallen trees, construction, or other hazards.
A buoy flashing a green light typically indicates a navigational aid marking the channel's right side when entering from the sea. In the United States, this is part of the lateral buoyage system, where green lights are used on buoys and markers to signify safe passage on the right side. Mariners should keep these green buoys on their starboard (right) side when navigating inland.
