Bill,
There was no water running down the wash at all this morning, even though the road in was still wet from the rain. It looked as if there may have been a trickle no more than a foot or two wide through the barranca yesterday or sometime recently, but no standing or running water in the barranca at all.
I think that this is pretty normal. When Rustic first opened there was a deep channel within the barranca, but in some places it was only a few feet wide. My guess is that it was cut from decades (centuries?) of run-off from storms like this last one, or worse.
There was definitely a lot more rain in the storm before that photo was taken, at least three times as much, and it fell over a shorter period of time.
But the real difference is that there had been a major fire that burnt the watershed for miles above the course, leaving little mature vegetation to stop the water. Here is a photo of the 11th green with the 13th fairway in the background. The fire damage around the course wasn't the major problem, it was the fire damage for miles above the course.
Fortunately, things have grown back since then.
