By the time of the Army Corp report conducted its inventory most of the North Fork Ditch had been lined with concrete. Many of the appurtenances were also concrete such as wasteways, intake structures and sluice gates. Of the 37 flumes, 32 were constructed of timber and only 5 were metal. The timber flume construction allowed them to be built with small changes or bends in the direction to navigate around boulders and hillsides. The metal flumes, by contrast, were best adapted to spanning a small ravine in a straight line.
With Folsom Lake water levels low in the autumn of 2016, I decided to hike from Rattlesnake Bar up the North Fork of the American River to see if I could catch glimpses of gold rush era history.

Recently I uploaded a map published in 1910 by the American River & Natomas Water & Mining Company illustrating their network of canals. The map is generally topographically accurate and includes some place names not found on previous or later topographical maps.

I recently found aerial photography from 1952 showing a free flowing north and south fork of the American River. Finally, I can […]
South of Horseshoe bar you will come upon what is referred to as the NFD viaduct. This is an impressive structure built to conduct the water over a small ravine. Easily 15 feet tall and 40 feet in length, large granite blocks were carefully stacked to create what looks like a dam.
It was perhaps the first publicly finance railroad in California. Unfortunately, the Sacramento, Placer and Nevada Railroad was cut short by an even larger publicly financed railroad know as the Central Pacific.

The new Rose Spring Ditch wound around the hill sides of the current Folsom Lake Estates and required two siphons.
