COMPANY INFORMATION

Company History

The Las Flores Water Company is a utility service which specializes in the treatment, maintenance and distribution of drinking water supplies and irrigation systems in central and northern Altadena, located just east of the Mountain View Cemetery. The company maintains two reservoirs and a well near the business office.

Las Flores Water Company, Inc. was organized in 1885 by charter members, Peter Gano and Dr. L. A. Wright. The original water source was located in Las Flores Canyon, an area at the top of Lake Avenue, just east of the Cobb Estate.

In 1881, prospectors mining for gold started tunneling in Las Flores Canyon. The tunnels extended into the mountain from about 400 to 600 feet, looking for gold. There was extensive gold prospecting between the years of 1886 to 1894. Instead of finding gold through the tunnels, they found water in underground springs. At times the water would flood the tunnels. The tunnels are still there today, but are sealed off so that no one has access to them. At times, the tunnel entries are covered and surrounded by large patches of poison oak. *

The shareholders are an integral part of the Las Flores Water Company. They number over 1,400 and are key to our success.
