Permit Cancellation Alerts
Selway permit just opened.
You have minutes.
Recreation.gov releases Selway River launch permits for the May 15–July 31 control season via a permit draw — and cancellations appear without warning. RiverTrip checks for openings every 3 minutes and sends an alert the moment one appears.
Most cancellations are claimed in under 10 minutes. Your crew can't afford to find out hours later.
