This photo is below the powerhouse at the Coleridge Dam. The metal tube with water dripping off it, it the dam's draft tube. It normally should extend down to below the water level. Draft tubes connect the turbine to the tail race, which is the lowest point in a dam, where the water ends up before flowing out and downriver. My friend, Bill, who owns this powerhouse, had to cut the tube since it had corroded. rather than replace the tube, he is going to cover the openings, seen below, with metal, in effect, creating a draft tube.
Here we are paddling away from the powerhouse. The two openings Bill is going to cover are the two which form the corner of the building right behind the canoe.
The purpose of out outing was to look at a rock garden, about 2/10s of a mile downriver. Bill thought he could remove some of the rocks in the rock garden, creating more declivity and a quicker current away from the powerhouse. It looked like bedrock to me so I don't think this can be accomplished.
Here is a bonus. We saw lots of Cardinal flower on this short paddle.
