Wayne,
I'm a huge believer in surface drainage. On many of our courses there are no inlets at all. On average, I'd guess there are about two places where we should have put one, to stop so much sheet drainage from going across a particular point in the fairway.
(An example ... Stonewall Two, which has no drains at all ... too much water comes back down the middle of the seventh fairway from the front of the green. We should have put a drain just past the landing area there.)
Pete Dye always said 95% of golf design is making drainage look good. He's fallen into the catch basin trap himself now, but I'm sticking with the old way for as long as I can.
BTW, the project manager at Cape Kidnappers wanted to put in a bunch of catch basins in the fairways on that site. It would have looked awful. I told him we ought to be able to figure out how to get it to surface drain, considering that we had 500 feet of fall to work with!
