Knight Foundry, also known as Knight's Foundry and Shops, is a cast iron foundry and machine shop in Sutter Creek, California. It was established in 1873 to supply heavy equipment and repair facilities to the gold mines and timber industry of the Mother Lode. Samuel N. Knight developed a high speed, cast iron impulse water turbine which was a forerunner of the Pelton wheel design. Knight Wheels were used in some of the first hydroelectric plants in California, Utah, and Oregon. This site is the last water-powered foundry and machine shop in the United States. A 42-inch (107 cm) Knight Wheel drives the main line shaft, with smaller water motors powering other machines.
