Casual water is always a free drop. Plugged lies (even in rough) are liftable during LCP... Plugged in a hazard is not applicable (traps, water...) However, Casual water in a hazard is a free drop (still within the hazard - if you cannot find a dry patch in the hazard, go home, becasue you shouldn't be playing in that much rain, unless you are from Scotland where they play in ANYTHING!!!)
