What Does a Lateral Water Hazard Mean in Golf?

Seeing red stakes lining a fairway or green can cause a spike of anxiety for any golfer, but understanding what they mean is the first step to confidently handling the situation. This guide will walk you through exactly what a lateral water hazard is, the options you have when your ball finds one, and how to use the rules to your advantage, saving you confusion and penalties on the course.

Red Stakes vs. Yellow Stakes: What’s the Difference?

Before we break down the rules for lateral water hazards, it’s a good idea to understand their official name in the Rules of Golf: Penalty Areas. The old terminology of "hazards" was updated in 2019, but you’ll still hear players (and even an article like this one) use the term because it’s so familiar.

There are two types of penalty areas, and they are marked by different colored stakes or lines:

• Yellow Penalty Areas (Yellow Stakes/Lines): These typically cross the direct line of play. Think of a creek that cuts directly across the fairway. The options for relief here are slightly more limited.
• Lateral Penalty Areas (Red Stakes/Lines): This is what this article is all about. These penalty areas run alongside or adjacent to the line of play. Imagine a river, lake, or thick wooded area that runs parallel to the fairway from tee to green. Because of this parallel nature, the rules give you an extra relief option that isn't available from a yellow penalty area.

The essential difference to remember is that the red stakes give you more flexibility. The rules recognize that because the penalty area runs alongside the hole, simply dropping "back-on-the-line" (a yellow stake option) might be impossible or would unfairly force you to play from an unplayable spot hundreds of yards away. The lateral relief option exists to provide a fair and logical way to get back in play.

Your Options from a Lateral Water Hazard (Red Stakes)

So, your ball has found its way into a lateral penalty area. Your heart sinks a little, but don't panic. Take a breath, assess the situation, and remember that you have several great options. Assuming a one-stroke penalty, let's go over your choices, from most common to least used.

First, one an important "no-penalty" option to consider...

Option 1: Play the Ball as It Lies (No Penalty)

Before you even think about taking a penalty, always check if you can play the ball from where it is. Thanks to the 2019 Rules update, playing from a penalty area is much more a_c_commodating than it used to be. You are now permitted to:

• Take practice swings that touch the ground or water.
• Ground your club right behind the ball at address.
• Remove loose impediments like leaves, twigs, and stones.

This is a game-changer. If your ball is sitting up nicely on the bank of a creek bed or just inside the red line on some pine straw, you might be able to save yourself a penalty stroke. Always weigh the risk and reward. If it’s half-submerged in mud or tangled in gnarly an‍k‍le-high weeds, attempting the "hero shot" is probably not your best bet.

Option 2: Take Lateral Relief (The Most Common Choice for a One-Stroke Penalty)

This is the special option you get with red stakes. It’s what makes a "lateral" hazard lateral. It’s almost always the most practical choice. Here's how it works:

Step 1: Find Your Reference Point

Your first job is to determine the point where your ball last crossed the edge of the red penalty area. This is a point of frequent confusion. It's not where your ball finished! If you hit a big slice that crossed into the penalty area 200 yards from the tee but then bounced forward and came to rest at 220 yards, your reference point is at 200 yards.

Step 2: Measure Your Relief Area

From that reference point, you can measure two club-lengths (using the longest club in your bag, which isn’t your putter) to create a relief area. This relief area cannot be any closer to the hole than your reference point.

Step 3: Drop and Play

Drop a ball from knee height within this two-club-length relief area. Once your ball comes to rest in the relief area, you are back in play. You are adding one penalty stroke to your score for this relief.

For example, if you sliced your second shot into a lateral penalty area, this would be your third shot playing from the drop area.

Option 3: Back-on-the-Line Relief (Also a One-Stroke Penalty)

Just like with a yellow penalty area, you have the back-on-the-line relief option available for a red penalty area. While less common, it can sometimes be the best strategic choice.

• Find the spot where the ball last crossed the edge of the red line.
• Imagine a straight line from the hole, through that spot, and extending as far back as you want.
• You can drop your ball anywhere on that line.

When is this useful? Imagine the lateral relief would drop you right behind a tree, but going back-on-the-line just 10 yards gives you a perfectly clear shot to the green. In that case, this option would be a lifesaver.

Option 4: Stroke-and-Distance Relief (Also a One-Stroke Penalty)

This is your final choice, and it's almost always the least appealing. You can always go back to the spot from where you hit your previous shot and play again. This is known as "stroke and distance" because you add a penalty stroke and lose the distance of your previous shot.

If you hit your drive into a lateral penalty area, this would mean re-teeing and hitting your third shot. For most tee shots or fairway shots, choosing Option 2 (Lateral Relief) is strategically better because it lets you advance the ball up the hole.

An Often-Forgotten Rule: Opposite Side Relief

Here’s a rule many seasoned golfers forget exists, but it could save you. For a red lateral penalty area only, you also have the option to take relief on the opposite side of the hazard.

You find a point on the opposite margin of the penalty area that is the same distance from the hole as your original reference point. From there, you can measure your two club-lengths no closer to the hole and drop. This is still just a one-stroke penalty.

Think about a hole where the right side of the lateral creek is all thick trees and unplayable lies, but the left side is perfectly manicured fairway. If your ball crosses into the penalty area on that tricky right side, being able to drop on the clear left side is a fantastic advantage. Not all courses are designed where this is possible, but always keep it in the back of your mind.

A Practical On-Course Walkthrough

Let's paint a picture. You’re playing a 400-yard par 4. A creek, marked with red stakes, runs all the way down the right side of the hole. You push your drive off the tee, and you see it bounce once before disappearing over the red line.

1. Walk toward the area. As you walk, you and your playing partners try to pinpoint exactly where the ball last crossed the invisible line between the red stakes. You determine it crossed about 230 yards from the tee.
2. Assess your options. You look into the hazard. The ball is sitting down in the mud. Playing it is not a wise move (Option 1). Going back to the tee box (Option 4) means you’d be hitting 3 from the tee, a loss of 230 yards. That's a bad choice. Back-on-the-line relief (Option 3) would put you in the right rough, which is playable but not ideal.
3. Take lateral relief. You decide on the best choice: Lateral Relief (Option 2). You take the reference point where the ball crossed at 230 yards. You pull out your driver, measure two club-lengths away from the penalty area deeper into the fairway (but no closer to the hole), and define your relief area.
4. Drop and play. You pull a ball out of your pocket, drop it from knee height, and it lands safely in play in your relief area in the fairway. You are now lying 2, ready to hit your 3rd shot, with a clear look at the green. That's how you turn a potential disaster into a manageable situation.

By calmly applying the rules, you gave yourself the best possible chance to recover and still make a par or bogey.

Final Thoughts

Understanding the rules for a lateral water hazard (or red penalty area) transforms a dreaded shot into a simple procedure. Just remember to find where your ball last crossed the line, evaluate your options, and choose the one that gives you a clear path for your next shot while correctly applying the one-stroke penalty.
