Rule 16.1

Casual water relief — when that puddle is actually free

Casual water is free relief under Rule 16.1 — the modern name is temporary water. If you can see standing water at your ball or under your stance, you drop within one club-length of the nearest point of complete relief, no nearer the hole, at no penalty.

The short answer

What counts as casual water?

Temporary water is any temporary accumulation of water on the surface of the ground — puddles from rain, an overflowing irrigation head, or water that has spilled out of a pond — that is not in a penalty area and can be seen before or after you take your stance.

The definition has a caveat most golfers miss: it is not enough for the ground to be merely wet, muddy or soft, and it is not enough for water to be momentarily visible as you step down. The accumulation has to still be there either before or after the stance is taken, without you pressing down excessively with your feet.

So if you press your foot down and water squelches up between the grass blades, that is not casual water. If there is a visible film or pool of water next to your ball when you walk up, it is.

The drop procedure, step by step

  1. Confirm the interference. Your ball must touch or be in the water, or the water must interfere with your stance or your swing.
  2. Find the nearest point of complete relief. Nearest spot — no nearer the hole — where the water interferes with nothing: not the lie, not the stance, not the swing.
  3. Measure one club-length from that point. That is your relief area. It must be the same part of the course (general area stays in the general area).
  4. Drop from knee height and let the ball come to rest inside the relief area. Roll out? Re-drop. Roll out again? Place it where it first touched the ground on the second drop.

The measurement starts from the nearest point of complete relief, not from where your ball sat in the puddle. Getting this wrong is the most common relief error in club golf.

Casual water in a bunker

If your ball is in a bunker and there is temporary water around it, you have two options:

You cannot take free relief out of a bunker. "I don't want to hit off wet sand" is not a free drop.

On the putting green

On the green you get free relief by placing — not dropping — at the nearest point of complete relief. And uniquely, if casual water on the green sits on your line of play, you get relief for that too. Line-of-play relief only exists on the putting green; everywhere else, an obstruction between your ball and the hole is not interference by itself.

The spillover rule

When a pond rises after heavy rain and creeps past the stake line into the general area, that overflow is not part of the penalty area. It is temporary water, and you get free relief from it. Check where the margin is actually defined before you assume you're stuck.

Frequently asked questions

Is casual water a free drop?
Yes. Casual water — now called temporary water — is an abnormal course condition under Rule 16.1, so relief is free. You find the nearest point of complete relief no nearer the hole and drop within one club-length of it.
What is the difference between casual water and temporary water?
Nothing — they're the same thing. 'Casual water' was the old term; the 2019 Rules of Golf renamed it 'temporary water'. Both mean a temporary visible accumulation of water on the surface outside a penalty area.
Do you get relief from casual water in a bunker?
Yes, but only free relief inside the bunker (using the point of maximum available relief if there is no nearest point of complete relief in the sand). To get out of the bunker entirely you must take back-on-the-line penalty relief for one stroke.
Does wet ground count as casual water?
No. The Rules are explicit that it is not enough for the ground to be merely wet, muddy or soft. There must be a visible accumulation of water at the ball or under the stance, before or after taking the stance without excessive pressing.
Is dew or frost casual water?
No. Dew and frost are excluded from the definition of temporary water and you get no relief. Snow and natural ice are different — you may treat those as either a loose impediment or temporary water, your choice.
