Bowling for Shade

The Los Angeles Department of Water and Power (DWP) dropped 400,000 HDPE recyclable black plastic balls into Ivanhoe Reservoir. The DWP drop was designed to stop sunlight from mixing with the bromide and chlorine in the 10-acre, 58-million-gallon Ivanhoe Reservoir. The 102-year-old facility serves about 600,000 customers downtown and in South Los Angeles.
