False The Definition of “Casual Water” states, in part, “”Casual water” is any temporary accumulation of water on the course that is notin a water hazard…” [Emphasis added]. Thus, any water within the margin of a water hazard is part of the water hazard, relief for which is available only by incurring a one-stroke penalty pursuant to Rule 26 [Water Hazards].
True See the Definition of “Casual Water” and Decision 25/2 [Overflow from Water Hazard].
False The Definition of “Casual Water” states, in part, “”Casual water” is any temporary accumulation of water on the course….” [Emphasis added]. As the puddle of water is out of bounds, it is not casual water. Therefore, you must either play the ball with your stance in the water, or deem your ball unplayable and incur a one-stroke penalty under Rule 28 [Ball Unplayable].
False Rule 25 [Abnormal Ground Conditions …] is the applicable Rule given that the Definition of “Abnormal Ground Conditions” indicates that casual water is an abnormal ground condition. Rule 25-1c [Ball in Abnormal Ground Condition Not Found] allows you to take relief without penalty by deeming the ball to be lying at the spot where the ball last crossed the outermost limits of the casual water. See also Decision 25-1c/1.5 [Clarification of Point Where Ball “Last Crossed Outermost Limits of” Abnormal Ground Condition].
False Rule 25-1a [Abnormal Ground Conditions: Interference] states, in part, “If the player’s ball lies on the putting green, interference also occurs if an abnormal ground condition on the putting green intervenes on his line of putt. Otherwise, intervention on the line of play is not, of itself, interference under this Rule.”
True See Decision 13-4/7 [Touching Casual Water in Bunker with Club] which states, “The player incurs no penalty as he did not touch the ground in the bunker with his club prior to making his stroke ….” See also Rule 13-4 [Ball in Hazard; Prohibited Actions].
True According to the Definition of “Casual Water,” snow is either casual water or loose impediments at the option of the player.
True The Definition of “Casual Water” states, in part, “”Casual water” is any temporary accumulation of water on the course that is not in a water hazard and is visible before or after the player takes his stance.” [Emphasis added]. See also Decision 25-1 [Soft, Mushy Earth].
