There's only water in play on 11, 12, 13, and sort of on 14. That's it. There are certainly some canyons and ravines as penalty areas on other holes, but not water. Three of those water holes are adjacent to the river, so they aren't exactly artificial; only one hole, 11, is highly artificial with its use of water. You see the river and the bridge from 6 holes, and only ~4 holes are down in the flat by the river. Most of the course plays through hills, canyons, and trees, but they don't show those holes on TV as much.
