Western Trips visited Nevada City California, one of the more famous of old California gold mining towns, to learn more about hydraulic mining for gold. Located in the beautiful Sierra Nevada mountains, Nevada City is home to many historic sites and one of those is the Miners Foundry built way back in 1856.
Nevada City California is one of the best towns in the Sierra's to experience the California gold mining era. The town has done a superb job in keeping and restoring some of the more famous gold era historic sites such as the National Hotel, the Nevada Theater and the Miners Foundry just to name a few.

There were several ways of finding gold in old California. Placer mining, tunneling and hydraulic mining were among those. Placer mining was the first stage. This was what the first of the Forty Niner's did to find gold. Placer mining is basically surface mining. Placer gold was the easiest gold to find. The problem was that at some point the easy diggings would play out and another method would be required. This is where hydraulic mining comes in and it had it's heyday in the early 1860's. What is hydraulic mining?
The best description of the effects of hydraulic gold mining can be found in the book Anybody's Gold by author Joseph Henry Jackson. Jackson describes the effects of hydraulic mining as a wholesale change of the landscape. This type of mining actually tore down mountains and filled the rivers with red mud. It was essentially an extension of placer mining except it was on a grand scale and made permanent changes to the topography which was very visible to the naked eye.

One effect of hydraulic mining on such a large scale was that the tons of sediment put into the rivers caused them to widen and change channels. Floods occurred in the Sacramento Valley. This filling of the rivers with red mud also interfered with steamboat traffic between Sacramento and Marysville.

The Pelton Wheel
Hydraulic mining of course required water and this led to other possibilities. Generally, water was brought down from the higher elevations and channeled through a hose.

An invention that really is the father of hydro power is the Pelton Wheel. The Pelton Wheel is named after it's creator, Lester Allan Pelton in the 1870's. The Pelton Wheel shown in this article is an exhibit at the Miners Foundry in Nevada City California. The wheel is an impulse turbine. It's purpose is to generate power from flowing water. The momentum of the water flow turns the turbine. Very large Pelton Wheels, sometimes referred to as water wheels, are used today in our hydroelectric energy plants and today's operations are a direct result of the first Pelton Wheel.

Nevada City California is located 60 miles northeast of Sacramento on Hwy 49. This is about 28 miles north of Auburn California which is on Interstate 80. Traveling from Reno Nevada, take Interstate 80 to the CA Hwy 20 exit which is about 58 miles west of Reno. Nevada City is about 26 miles west on CA Hwy 20. If you want to learn about finding gold the way the miners did with hydraulic mining, Nevada City California and the Miners Foundry is a good addition to your Sierra Nevada trip planner.
