I started hiking from the Folsom Lake Peninsula campground down to the tip of this stretch of land. Usually underwater, the drought of 2015 had drained the lake down to 15% of capacity. This exposed lake bed that is rarely visited during normal lake levels. Like many people I tripped across sunken boats, abandon gold mines and a surprising number of dams.
For history buffs there is nothing closer to heaven than examining an old map. I share that fascination and also enjoy sharing old maps that I’ve found. 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 had always noticed Rose Springs and Rock Springs marked on maps that encompassed the south Placer county region we know today as Granite Bay. It wasn’t until Folsom Lake hit historically low water levels that what I think are Rose and Rock springs became apparent to me.
With the North Fork of the American River actually flowing around Rattlesnake Bar since the stationary waters of Folsom Lake didn’t occur until around the bend at Horseshoe Bar, I figured I might be able walk across the river to explore Goose Flats and the old mining operations. I thought if the miners of the 1850’s could ford the river so could I. Much of the bottom and banks of the river are choked with mud, muck and sediment as the lake elevation can be eighty feet above the river bed at Rattlesnake Bar.
A 2015 drought depleted Folsom Lake has allowed a rare opportunity to hike from the current Salmon Falls bridge over the South Fork of the American River all the way down to the old bridge which is usually covered by Folsom Lake. What makes this hike so special is that the South Fork of the American is flowing free like a river should.
In 1849 U. S. Army Lieutenant George H. Derby performed topographical survey of the Sacramento Valley. The “Topographical Memoir Accompanying Maps of the Sacramento Valley, &c.” was found in Quarterly of the California Historical Society Vol. XI No. 2 publication dated June 1932. I found the small quarterly report in a book store in San Francisco and was attracted to it because of the inset map of the Sacramento Valley. The map is a reproduction of Lieutenant Derby’s topographical map he made for his report.
These photos along with a short review of the project and photographer originally appeared in the 1964 issue of Diggin’s from the Butte County Historical Society, Voume 8, No. 1, Spring Edition.

So much good history is underwater. Our 20th century dam building covered in water many interesting historic artifacts such as the remnants of a 19th century dam and diversion canal on the Feather River. A small paperback titled “Lost Beneath The Feather River” and a brief story published in Harper’s Weekly clued me into this […]
The North Fork of The Middle Fork trail is a short little hike right off Mosquito Ridge Road. It is so named because it parallels the North Fork of the Middle Fork of the American River. Because the Placer County Water Agency maintains a dam up-stream this part of the river should have flowing water virtually […]
Tunnel Engineering – A Museum Treatment by Robert M. Vogel is a brief history of engineered transportation tunnels published in 1964. The booklet was part of series that accompanied scaled model displays illustrating the advances in tunneling primarily in the 19th century. The short thirty-six page bulletin focuses on how modern engineering design evolved as […]
