We have a stream running across a couple of fairways that has flooded over it's normal limits. The PA is marked with yellow lines
How should the club identify the difference between the PA margin and the Temporary Water?
Voyager's suggestion seems best to me, especially as there is a steep drop into deeper water. But is the edge of the overflow itself adequate definition of the margin of the NPZ? Perhaps stakes around the edge.
Is this a one-off occurrence Or does it happen with any degree of frequency? If the latter, perhaps one should consider permanently marking the edge of the PA with stakes tall enough to show above the floodwater?
Making the whole area of water a No Play Zone would not in itself solve the problem, There would still would still have to KVC of his ball being in the temporary water for a player to get free relief; without KVC his ball is taken to be in the PA and relief though mandatory still comes with a penalty. Easily sorted, however, by defining it all as a No Play Zone in GUR.[Edit: I wrote that last sentence off the cuff but now have great misgivings about it. The stream is a Penalty Area by Definition and incorporating it in GUR does not change its status does it? You do not get relief from an abnormal course condition in a penalty area and so you will still cop a penalty stroke for the mandatory relief from the NPZ. I hear my father's voice in my head, "Think again laddie, think again".]
Note too that a NPZ would it necessarily ensure safety as it only prohibits play from the NPZ, not entry into it.
