Keep the marker to your port (left) side. Heading down stream it'll be to starboard.
Usually there will be a red marker to the starboard headed upstream, and you should keep between the buoys , sometimes there will be midstream buoys, or even preferred channel markers, marking safe deep water channels. They will be red over green, triangular, lettered or even numbered for starboard markers, and green over red, square, lettered or odd numbered for port side markers. Center channel markers may be yellow or white, hazard markers are black over white, or black over red. Inter-coastal waterway markers are yellow.
States have their own marker systems, heading up current though in all systems will be green to port, red to starboard and black marking hazards.
Lighted markers follow the same rules, green to port, red to starboard and white for hazards heading in from the sea/ocean. If the lights are moving they're on a vessel, stopped or anchored vessel should only show a white light or lights. Yellow lights indicate a vessel under tow.
Keep a green lateral marker to your left, or port, side when proceeding in the upstream.
If you are traveling in a primary channel and you encounter a red and green marker (with the green band on top) when proceeding in an upstream direction, what must you do?

You MAY pass on either side of the marker
If you see a buoy with the number 5 and a green flashing light while traveling upstream, it indicates that you are approaching a channel marker. The green light typically signifies the right side of the channel when navigating upstream. You should keep the buoy on your right side and proceed cautiously, as it marks the safe navigable waterway. Always be aware of your surroundings and any potential obstacles in the water.

If you see a buoy with the number 5 and a flashing green light while traveling upstream on a river, you should keep the buoy on your starboard (right) side. The green light indicates that you are approaching a navigational marker, and maintaining this position will help ensure safe passage. Continue to monitor your surroundings and proceed cautiously, especially as it is dusk and visibility may be reduced.
If you see a green square day mark while going upstream, it indicates that you are approaching a navigational hazard or point of interest on your right side. You should maintain your course and ensure you are navigating safely, keeping the mark on your right as you proceed. It's essential to stay alert for any additional markers or changes in the waterway ahead. Always follow local navigation rules and guidelines.
::Keep the marker on your starboard (right) side
This is a channel marker, placed on the edge of a channel. Green markers will always have an odd number on them. If you are heading upstream it should be to your left. If you are heading downstream it should be to your right. It will be opposite a red marker or bouy with an even number on it. To aid in navigating, the term "red, right, returning" is used meaning as you return from open waters (head upstream), the red marker, bouy, sign etc, should be to your right. That means the green one, in your example with a 3 on it, should be to your left. If its on your right side, you are outside the cleared channel area.
