Send someone out to rake the bunker after it rains. If you don't have someone, get rid of the bunkers. There is no magic in golf course management
Don is correct, there is no magic in golf course management but also there are a lot of practical, economical and common sence solutions out there, that are often overlooked by the industry!
Randy,
I understand what your saying here and I liked your drainage ideas, but read this thread. You've got all kinds of ideas including the "call me if you want the best" approach. All I'm saying is you can do whatever you want, add drainage, klingstone, sportcrete, bunkerwall, sand mat, sand trapper, astro turf, sod, billy bunker, yada yada yada, and your still going to go out and rake the face of that bunker after a substantial rain. The first thread says the bunker face is a problem, bunker faces are always a problem. The #1 issue here is a poorly constructed bunker. As Ron White says, you can't fix stupid, and in this case you either fix the bunker using someone who knows what he's doing, or just rake the sand. Raking the sand probably makes the most sense. Its not a sexy alternative, but what would everyone do if it were your money? Adding some perf above, or just below the lip, of the bunker will help, some, but it will not prevent washouts.
