But it's not a lake, it's two ornamental ponds connected by a monstrosity of a mock waterfall, absolutely awful. (IMHO of course )
Off the whites, the first should not have much impact - but from the black it will have a bit more impact although still unlikely to catch people out unless you mishit - although it will be a more substantial carry - not sure exactly but probably 160ish.
18 will certainly come into play in 2 ways. 1. for the longer hitters - probably about 300-315 depending on angle off the whites - add 40 for blacks. It will be quite imposing for second shots, especially if you are left off the tee and/or in the rough as it could be a full carry. They are pushing the fairway wider on the right to give more of a bail out to use for a 3 shotter
