My situation was a little different in the hazard was red staked, however, there was no water. It was where a creek once ran through, and occasionally is used as run off when it rains here, but 99% of the time it is dry. When not filled with water all that remains is tall grass. When I made my back swing I hit the grass on the edge of the dry creek bed and incurred a penalty. Maybe after reading this I shouldn't have received the penalty? At the time it didn't matter as I was only in contention for last place, but for future reference I better clarify it, as it is my home course and I play tournaments 2 times a month or more here.
