Los Angeles protects open


Los Angeles Mayor Eric Garcetti, in suit at center rear, and LADWP workers deposit the final batch of over 90 million "shade balls" into the Los Angeles Reservoir in the Sylmar area of Los Angeles. The plastic balls were placed to protect water quality and to save 300 million gallons of water a year from evaporation. (Art Mochizuki/Los Angeles Department of Water and Power via AP)
