Having been running Brown's both private and commercially for over 30 years now, it is pretty predictable when it will be busy and when I can go and have it all to myself. If you want to run it during the late morning/mid-day, expect it to be busy. Earlier and later you can find plenty of solitude. There is even a sweet spot between the primary morning and afternoon commercial launches where traffic can be sparse if you time it right.
I've also never had difficulty getting ramp space at the take out regardless of time of day, but Ruby Mtn. sometimes gets a little congested being so small. For the traffic Brown's sees, things generally go pretty smoothly with only an occasional shit show.
I just hope that the powers that be will consider the concentration of boats in time windows when developing a permit system. There is no reason for permits if you are launching before 8 or after 4.
I can't speak to Tom Waters, who is now the park manager with the retirement of Mr. Revenue, Rob White, but the thinking back in 2003ish when this was being considered the first time the privates hit their allocation, was 24/7 365 permits, as the carrying capacities were designed for a 24 hour period. One point I brought up was the lack of people counting outside of "business hours", how would they track use? The reply I got was they would track the permits. Personally, the ONLY areas a permit system would work is in the gorge and browns, as all the other areas have way too many access points to be able to control. I hate to say it, but it's likely imminent, the commercial SUA people won't not let it happen. They have a huge wad of panties for the privates, feeling they hinder their operations, and impact their customers enjoyment..
The Ark has long since lost all the "mom and pop" operators, the last to go was WAO downstream, now it's all business people, and it's a big business indeed. Talking with a guide for Echo last night, he said visitation is off at least 1/3 this year, despite decent water. The thinking amongst the guides is gas prices and rampant inflation is stopping people from traveling, so it may well be a good year to boat and miss some of the crowding.. Just not in Browns..
