What It’s Called: Understanding "Penalty Areas"
While most of us call it "hitting it in the water" or finding a "water hazard," the official term in the Rules of Golf is a Penalty Area. This change was made in 2019 to better describe all sorts of tricky spots you don't want to hit your ball into, which might include lakes, ponds, rivers, and streams, but also ditches, jungles, or rocky deserts that the golf course has decided to mark as a penalty area.
The important thing to know is that these penalty areas are marked in one of two ways:
With yellow lines or stakes.
With red lines or stakes.
The color is not just for decoration, it is the most significant factor in determining what your options are. Red penalty areas give you more relief options than yellow ones. Identifying the color of the stakes or line around the water is the first step to figuring out your next move.

The Two Colors of Trouble: Yellow vs. Red Penalty Areas
When your ball ends up in a penalty area, the fundamental principle is that you get one penalty stroke, and then you must take relief. The color of the line dictates how you can take that relief.
Yellow Penalty Areas (The Traditional "Water Hazard")
A yellow penalty area is a body of water or other area that is typically positioned between you and the putting green. Think of a pond directly in front of a par-3 green. Because of this positioning, the rules for a yellow area are a bit stricter to prevent you from gaining an unfair advantage.
When your ball finds a yellow penalty area, you have three options after taking your one-stroke penalty:
Play It As It Lies: You always have the option to play your ball from inside the penalty area without a penalty. However, this is rarely a good idea. If your ball is submerged, it's virtually impossible. If it’s sitting on the muddy bank just inside a yellow line, it might be tempting, but it’s a very high-risk shot. Most of the time, it's better to accept the penalty and take your drop.
Stroke-and-Distance Relief: This option is always available for any penalty area, red or yellow. You can go back to the spot where you hit your previous shot and hit again, adding a one-stroke penalty. So if you were on the tee, you’d be re-teeing, now hitting your third shot. If you were in the fairway, you'd drop a ball at that spot and hit your next shot.
Back-on-the-Line Relief: This is the key relief option specific to yellow areas. You must figure out the estimated point where your ball last crossed the edge of the yellow penalty area. Now, imagine a straight line from the hole through that point where your ball crossed, and extending backward as far as you want. You must drop a ball on this line. You can go back 5 yards, or 50 yards - as long as you stay on that line. You then get a one-club-length relief area from where you drop your ball. This is often an excellent option if it gives you a comfortable distance and angle for your next shot.
Red Penalty Areas (More Options, More Flexibility)
A red penalty area, formerly known as a "lateral water hazard," is an area that usually runs alongside the hole. Think of a river running parallel to a fairway or a pond on the side of a dogleg green. Because you aren’t required to hit over it to continue, the rules give you more flexible relief options.
When your ball finds a red penalty area, you have four options. You get all three of the yellow penalty area options, plus a fourth, very helpful one:
Play It As It Lies (same as with yellow).
Stroke-and-Distance Relief (same as with yellow).
Back-on-the-Line Relief (same as with yellow).
Lateral Relief (The Game Changer): This is the additional - and often best - option for a red penalty area. First, identify the point where your ball last crossed into the red penalty area. From that spot, you can measure two club-lengths (using the longest club in your bag, other than your putter) to create your relief area. You can drop a ball anywhere inside this two-club-length area, as long as it’s no closer to the hole. This is fantastic because it lets you drop right beside the hazard without losing significant ground, unlike the back-on-the-line option which might force you to drop much farther away or in a terrible spot.
A Step-by-Step Guide to Taking Your Drop
Alright, your ball is wet. Let’s not make a bad situation worse with a rules mistake. Just follow these steps calmly and you’ll be playing again in no time.
Step 1: Identify the Color of the Penalty Area
Walk up to the hazard and immediately look for the stakes or lines. Is it red or yellow? This determines the full set of choices you have.
Step 2: Determine Where Your Ball Crossed the Line
This is all about your "best reasonable judgment." Follow the path your ball took in the air and identify where it crossed into the yellow or red area. Point to a spot on the ground - maybe a specific weed, a piece of bare dirt, or the edge of a bunker. This point is the reference for either your back-on-the-line relief or lateral relief.
Step 3: Review Your Options and Pick the Best One
Quickly think through your choices based on the color.
If it's YELLOW: Do I want to go all the way back and re-hit (stroke-and-distance)? Or is there a good spot on the back-on-the-line relief?
If it's RED: All the yellow options apply, but is the lateral relief option (two club-lengths, no closer) my best chance? In most cases with red penalty areas, it is. It lets you get back in play quickly without losing too much distance.
Step 4: Execute the Drop Correctly
This is a big one that a lot of golfers still get wrong. Since the 2019 rules update, you must drop the ball from knee height. Let the ball go from your hand and let it fall straight down. It can't be thrown or spun. The ball must land in your designated relief area and come to rest there. If it rolls out of the relief area, you must re-drop. If it rolls out a second time, you place the ball where it first hit the ground on your second drop.
Step 5: Play On!
Once your ball is correctly dropped and at rest, it’s in play. Forget about the penalty stroke - mentally, you’re starting fresh. Commit to your next swing and focus on making a great shot.

The penalty area rules can have some nuances. Here are answers to a few common head-scratchers.
What if I'm not sure if my ball went into the penalty area?
To treat your ball as being in a penalty area, you must be "virtually certain" it’s in there. This means 95% or more sure. If you have any serious doubt - maybe it could have bounced out or plugged in the deep rough right beside the water - you must treat it as a lost ball. This means you have to take stroke-and-distance relief, which can sometimes be much more punishing.
Can I ground my club in a penalty area?
Yes! This is a massive change from the old rules that many golfers haven’t caught up with. You are now allowed to ground your club lightly behind the ball and take practice swings that touch the ground or water inside a penalty area. This makes playing a ball "as it lies" from a penalty area much more manageable if you ever decide to try it.
Does the ball have to be actually *wet* to be in the penalty area?
No. The penalty area is defined a bit like out of bounds - by the inside edge of the line or stakes. If your ball is sitting on perfectly dry grass but that grass is inside the red or yellow line, your ball is *in* the penalty area. The same rules apply.
