Upper limit for best boatability uncertain. Please help your fellow boaters with a comment or report.
Funnel is the main event of the Lower Millers. The river constricts and picks up some gradient forming a class III rapid. It starts off with rocks forming holes as the gradient leeds to a ledgy part of the constriction which forms some good standing waves and holes. These waves are great for surfing with some decent eddy service. The water here is moving fast and and swim here can take a bit to collect as there isn't a big pool below, so boaters or gear can quiclky end up downstream.
