Just launch and find the first camp after the day section and layover till it comes down. I’ve launched at 9k (14k at take out) made it to camp right above ledges and layed over for a day till it dropped to around 6k.It’s honestly pretty straight forward for the first day at high flows, yeah big holes but just raft heads up and run tight. Totally worth it. Also I have had my truck loaded up 3 time and do to some kind of bullshit (roads,snow,low flows) never left the drive way. I would never question launching at high flows if I was with a good group. I’ve been told 15 at take out is when you should be concerned. Use that gauge not the put in gauge to decide if your making a bad decision.What you want a picture of my fully rigged truck parked in my driveway in Colorado pointed south and not moving.
