Amid controversy over steep utility rate hikes for Los Angeles Department of Water and Power customers — some in the thousands of dollars—CBS California Investigates took a closer look at how rates compare to other utilities in the region, and at the high salaries of dozens at LADWP. CBS California Investigates found that eight supervisors and one executive at LADWP make more than $700,000 a year, and more than two dozen supervisors make more than $600,000 a year. LADWP says many of those supervisors are people who supervise crews in the field.
