never went to Corbett when I was down there but from the pics I saw it was always DEEP water...they are in a drought but it's also the dry season, go back out there in July/Aug/Sept and I'm sure it would be wet. I'm sure you're finding out where the spots are but for reference keep an eye/ear out for the Holy Lands, The Hump, Lost Lake, and 8th Street/Bird Road. The wheeling is definitely different there, lots of black muck but even a lot of that has rock at the bottom so you get traction.
