Description
This is the first big drop. Get out and scout on what remains of the dam. The dam is made out of large rock slabs and concrete. There is a break on the left side of the dam. The water drops approximately 3' vertically then another 3' over a 30' distance as it curves from left to right. This channel is very narrow even in high water. What makes it more difficult are a pair of boulders in the middle of the channel halfway through. These force the paddler to the outside wall. Always scout this drop since debris occasionally lodges in the channel. Boat scouting is difficult because it drops steeply around the corner of the dam. Immediately below the dam there is a small 2' ledge under the railroad bridge.
