The red stakes on a golf course indicate a lateral water hazard. A lateral water hazard is different from a normal water hazard for it is lateral or it runs alongside the line of play. Simply put, a normal water hazard runs across the line of play while the lateral water hazard runs adjacent to the line of play
The red lines on a golf course also indicate a lateral water hazard.
It is worth noting that a single body of water hazard could have its side marked differently depending on whether its parts run adjacent or across the line of play. That is to say a water hazard could have a yellow stake or line from one side and a red stake or line from the other side depending on its position and coverage on a golf course.
*You either play your ball (if possible) or apply the one-stroke penalty and take a drop for having your ball in a lateral water hazard.
*There are two options to drop a ball in this scenario. One is by dropping your ball within two club lengths of the point where the ball crosses or touches the hazard, no nearer the hole. The other is to go to the opposite side of the lateral water hazard and drop your golf ball at a spot on the hazard’s margin that is equidistant from the hole. All of these are explained in detail in Rule 26.
