Older Lotteries - Demand, Statistics and Calendars 

Individuals can only have one reservation at a time during the lottery season for each river. For the Selway, the Salmon, and the Middle Fork of the Salmon, there is a limit of one permit per lottery control season per person.


Pre/Post Season Reservations: Each river has different reservation/permitting requirements for pre/post season trips. For details, click on the river name at the bottom of this page. For a summary about each river, see Whitewater Rafting on the Four Rivers page.

Reservations for 2019 pre/post season launch dates on the Middle Fork Salmon and Wild Main Salmon rivers was delayed from the typical October 1st opening. The start time will remain as 8 am Mountain time, but the date was pushed back to October 15 for just this year. The Wild Main Salmon River has unlimited launches for pre/post season dates. The Middle Fork only allows 7 launches per day throughout the year.

To reserve pre or post season launch dates, go to and search for the Salmon River or the Middle Fork of the Salmon River, or call 1-877-444-6777. Reserving a pre or post season launch date does not exclude the person from applying to the lottery.

The website is also the method boaters will use to update their reservation details, or to cancel their reservation if necessary. This is also the place to submit payment of recreation fees for the Middle Fork and the Main Salmon Rivers. Complete and final payment of recreation fees must be entered in your reservation prior to your launch date; payments will not be accepted at the launch sites.
