CRT2018: Wooden Pipeline

While parking to try a hike to nearby waterfall, we saw this water pipeline cutting through the parking area. The most amazing thing about it? It's made of wood. The whole thing is made of wooden staves, with metal rings cinching everything tight. It was leaking in a few places, but the idea that this huge wooden pipeline was carry all that water under so much pressure was amazing. I read that it is part of a hydroelectric project.
