Now You See it… Now You Don’t Olmstead Spillway
If you looked at the cliffs above you in 1904, this is the spillway for the Olmsted Flume you would have seen. Notice the size of the timbers used for construction and the water spilling from the overflow.
In 1949, the wooden flume was replaced with a steel pipeline and a siphon spillway instead of an overflow spillway. The pipeline shown in this photo is encased in the concrete you now see on the cliff face.
