Are you looking to do day trips, or an overnight trip or either?
The odds are good that there will be folks arriving prior to Wednesday, and it is quite possible that an overnight trip will materialize the week prior to the Rendezvous, but it is a bit early to predict that.
In addition to the North Fork of the White River, the Jack's Fork River, Current River, and the Eleven Point River (all in Missouri) are relatively close by. The Spring River (flowing out of Mammoth Spring) in Arkansas is also close, and the Buffalo (also in Arkansas) is not too far away. The Spring River has some vertical ledge drops (up to 5 or 6 feet) that you might not be inclined to take a nice composite boat over.
The Current, Jack's Fork, Eleven Point and Spring are all spring fed and nearly always have enough water to paddle some portion. The Buffalo is dependent on natural flow. Last spring it was really too low around the time of the Rendezvous but this year might be better. Time will tell.
The Current, Buffalo, and Eleven Point are all good for multi-day trips. Multi-day trips can also be started on the Jack's Fork, but the water quality on the Jack's between Eminence and Two Rivers is not very good and the water level above Alley Spring might not be sufficient in early May. The North Fork of the White and the Spring River are better suited for day trips.
