Just got off of an 18-day trip through the Grand Canyon on 11/1 and I was amazed at the beach erosion that had taken place in the 8 years since I'd been there. All that sediment is piling up at Lake Mead and now the old take-out, Pierce Ferry, is full of sediment and one now has to go 30 more miles to the next take out. The place is getting messed up from that damn dam. Rapids like Crystal will be unrunnable soon unless there is a big flush to clean some of that shit out like pre-dam days. And we're talking 70,000+ cfs not the 40k cfs joke of an experiment they did in the late 90's.
