Excerpt from Wikipedia
The North Fork Dam is on the Clackamas River, about five miles upriver from Estacada, Oregon. It was built in 1958. The North Fork Reservoir is behind it.
Construction
It is a concrete arch dam, 206 feet high and 676 feet long, is thin-shell of variable thickness. It varies in thickness from 32 feet at the base to 8 feet wide at the top.
The fish ladder
North Fork's construction entailed the building of the 1.9-mile-long North Fork Fish Ladder, one of the longest in the world. It also required a complex system to provide for downstream fish passage around the dam.
