When going upstream, a buoy with a number 5 and flashing green light indicates the presence of a dam ahead. The dam may be used to generate hydroelectric power or to provide water for irrigation, and can pose a danger to boats and other vessels.
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.
Since this is a Green Lighted Buoy sighted while approaching a harbour,this is a Lateral port hand side mark, IALA region B. To keep this buoy on your port side while travelling upstream.

because flashing green lights mean go and the green lights that are not flashing mean stop

Yes, when going upstream, red buoys should be passed on your starboard side. This follows the IALA (International Association of Lighthouse Authorities) buoyage system, which indicates that red marks are to be kept on your right when navigating upstream. Consequently, green buoys, which are passed on the port side, will be on your left. This system helps ensure safe navigation and consistency on waterways.
