The Barry Burn and other ditches at Carnoustie come into play a few times, although not all cross the fairway at the usual driving zone distance - 1, 2, 3, 5, 6, 10, 12, 16, 17, 18 etc.
And the crossing burn at the 10th received some unexpected tee-shot business at last years Open although that probably says more about the current ball/equipment situation than the burn itself.
One of the great skills in golf used to be judging the distance with the naked eye how far away is a hazard like a crossing ditch and then laying-up or going-for-it accordingly, especially in the wind or on variable firmness fairways. Less of a skill nowadays what with yardage books, rangefinders, sat-nav data etc.
