Stony Creek Road is an approximately 9.6-mile rural highway located in the Sierra Nevada foothills of Amador County, California. Presently the highway begins at Buena Vista Road near the Pardee Reservoir and terminates in Jackson at Argonaut Lane. During the Gold Rush era Stony Creek Road connected Jackson to Westmoreland's Suspension Bridge at the Mokelumne River in the community of Lancha Plana.
Part 1; the history of Stony Creek Road
Stony Creek Road was originally developed as a stage road between Jackson and Lancha Plana at the Mokelumne River. Lancha Plana had been settled by Mexican Miners during 1848 and had continuous Post Office service from 1859-1919.
Lancha Plana was located at the crossroads of stage routes to Jenny Lind and Jackson. In 1856 Westmoreland's Suspension Bridge was constructed at the Mokelumne River to facilitate easier crossings between Amador County and Calaveras County.
Westmoreland's Suspension Bridge is referenced in the September 1950 California Highways & Public Works as being 300 feet long and being built to a standard which withstood the infamous floods of 1862. The article stub notes the structure was then in a state of abandonment with the cables rusted and timber deck lost to age.
What is now Stony Creek Road can be seen connecting Lancha Plana to Jackson on the 1882 Bancroft's map of California.
Lancha Plana and the site of Westmoreland's Suspension Bridge can be seen on the 1889 United States Geological Map of Jackson. Westmoreland's Suspension Bridge was located immediately west of modern Buena Vista Road.
Stony Creek Road at Carson Creek would be modified due to construction of the Pardee Reservoir. The East Bay Municipal Utility District began construction of Pardee Dam during July 1927. Pardee Dam as noted above is a 358-foot-high concrete structure which impounds the Mokelumne River to form the Pardee Reservoir. Pardee Dam was named in honor of George Pardee who was once governor of California, mayor of Oakland and president of the East Bay Municipal Utility District. Pardee Dam was completed by 1929 and to hydroelectric power operations on June 23. Pardee Dam included a new roadway which crossed the top of the dam structure. The completed Pardee Dam can be seen below in the Calaveras County Historical Society photo.
The 1935 Division of Highways Map of Amador County is one of the last to display Lancha Plana and the site of Westmoreland's Suspension Bridge in substantial detail. Westmoreland's Bridge can be seen spanning the Mokelumne River and connecting Buena Vista Road with Calaveras County. Stony Creek Road is shown as a major county highway shown branching west directly through Lancha Plana into Calaveras County towards Camanche. It isn't clear when Westmoreland's Suspension Bridge was abandoned.
The remaining balance of Stony Creek Road is shown on the same map as a minor county highway from Township 5 North, Range 10 East near the Pardee Reservoir northeast to Jackson.
Pardee Dam Road has a northern terminus at Stony Creek Road. The beginning of modern Stony Creek Road itself is located about a half mile to the west at Buena Vista Road.
From Pardee Dam Road the corridor of Stony Creek Road begins a northeasterly trek towards Jackson. The highway crosses over small one-lane dam enclosing the Pardee Reservoir at Carson Creek.

Stony Creek Road continues northeast from the Pardee Reservoir and terminates in Jackson at Argonaut Lane. The corridor crosses over Jackson Creek and rolls through the terrain of the Sierra Nevada foothills. The below photos were taken by Josh Schmid during the Spring of 2025.
