Check the gauge first
A lot of these rivers are flow-dependent, especially the Owyhee, Dolores, and Bruneau. No water, no trip. The CFS on this page is a snapshot - always check USGS gauges the week before you go.
Self-issue is still free
"Self-issue" just means fill out a form at the put-in or email the local BLM office. Takes 2 minutes, costs nothing. Some rivers have a register box at the launch. Some you email ahead. Details are in each river's info link above.
Bring a groover
Every multi-day river trip requires you to pack out human waste. If you're new to this, rent one from your local raft shop and have them show you the setup. A fire pan and ash carry-out are standard too. Your local shop will sort you out.
