Stone mason aqueduct
A few days ago I posted a photo I shot at Folsom Lake showing a high curved rock wall. I took my initial pictures from a distance and didn’t have a chance to explore the wall more closely — but when I got home and started looking at the area on Google maps, something odd caught my attention.
The screenshot shows the lake at a higher water level, but the curved structure can be seen, cutting across a small inlet. I was determined to examine that spot when I returned to the lake last Thursday and to hopefully learn more about this stone wall.
I was hiking from south to north, following the path of the former North Fork Ditch which is now mainly used — when it is out of the water — by hikers, mountain bikers, and equestrians. Although it’s easy enough to walk across the top of the wall structure, the main trail actually loops around behind it; you can easily see this on the screenshot above.
I’ve consulted to Kevin Knauss’ book Hidden History: Beneath Folsom Lake as well as his blog (specifically this post, which includes a short video) for more information about this unusual feature of the Folsom Lake landscape. On his blog he refers to the structure as a “viaduct,” although in the book he more properly calls it an aqueduct, since its use was more likely related to water rather than transportation.

Wow!!! Who Knew??? Thanks for the great investigation!
Great pictures and explanation! I hike this area several times a year and like it when I find articles like this!
Thanks! It’s always cool finding unexpected stuff like this structure, especially when they’re related to history. 🙂
I feel the same way! I love taking pictures of the foundations and old pipes and ditches and bridge abutments that are usually covered with water. I was at the Rattlesnake Bar State Park area this weekend to see the abutments of the old bridge there. I have been to that park many times but this was the first time the water was low enough to see the place where the bridge used to be!
