If the stakes are short (if they are not intended to go to the bottom) then the only thing holding the "log" in that position is the man's arm. Otherwise the "stakes" would flip the log around via gravity and be sitting horizontally rather than vertically (assuming this is a physical structure).
If it were a pipe, rather than a log, it would sink lower in the water. Assuming the "pipe" ends where we see the cutoff point.
Actually, even if it were a log, it wouldn't be above the water like that unless the stakes were holding it up, so it doesn't match physics very well.
Is the man sitting (like on the steps of a spa)? If so, the "stakes" don't have to go down as far.
