Boaters should try to anticipate high and low water levels before submitting an application or reserving a launch date.

Reservations for pre- and post-season launch dates on the Middle Fork Salmon and Wild Salmon rivers are released annually at 8 AM Mountain time on October 1. The Wild Salmon River has unlimited launches for pre/post season dates, but the calendar will display 99 so boaters can see how many reservations have already been made. The Middle Fork of the Salmon River limits the number of launches per day to seven (7) throughout the year.

To reserve pre or post season launch dates, go to and search for the Middle Fork of the Salmon River or the Salmon River (4 Rivers). Reserving a pre or post season launch date does not exclude the person from applying to the lottery.
