The Mokelumne River Development of the Pacific Gas and Electric Company

Studies of topography and run-off have made possible a comprehensive development of the power resources on the Mokelumne River in California. Originally developed in 1902 to yield 100 million kw-hr. annually, additional storage and increased generating facilities will produce a ten-fold increase in annual output. Two major storage reservoirs and four power houses, one of which replaces the original plant completed in 1902, are included in the program. The entire project is expected to be completed by the summer of 1935 at which time the total fall of more than 5,000 feet available in the Mokelumne River drainage area will have been put to the most economical usage.
