Description

The main flow of this channel (downstream of 'The Trolls') slides down shallow bedrock, then drops over a short ledge which forms a Uniform Gnarly Hydraulic (UGH!) which should be avoided by most boaters at almost all levels.

The right-most side (furthest-right-side of photo above, midground/center up/down frame) may be runnable (even minor playable) at some flows, but always scout from the new public access along here before putting on, to know whether this is reasonable or not! The lower dam (mentioned by the warning signs above the railroad bridge) is not far downstream. (The 'superstructure' on the dam, mentioned elsewhere in the description, is visible in the distance center-frame.) Anyone who ends up swimming here will be swept toward that lower dam, and will be largely at the mercy of where the currents take them to spill over the dam.

The other option (below The Trolls, at two-gates or higher) is to avoid UGH altogether using a route far left (center-foreground toward frame-left), down a series of waves over shallow rocky debris then spilling over a short ledge. With enough water, a few diagonal waves and holes may allow surfs before you spill into the slackwater below.

As previously mentioned, there is a landing below on the right shore of this channel, just before meeting the currents sweeping from right-to-left across river by the lower dam. You can use this landing to make multiple runs of The Trolls, or (when ready) continue with PART III of the run.
