Toluca Lake is the centerpiece of the San Fernando Valley community of the same name. Though the lake was once fed by natural springs, changes in groundwater use in the area necessitated human intervention. Today residents of Toluca Lake CA must maintain their lake by pumping in well water in order to continue to enjoy it as a backdrop for their lives. The lake is entirely private and only accessible to owners of adjacent properties or members of the Lakeside Golf Club. Are you looking for ways to add value to your property in Toluca Lake CA?
