The final 20,000 of 96 million black ‘shade balls’ are released into a reservoir to help conserve water in Los Angeles.
City officials hope millions of “shade balls” released into the Los Angeles Reservoir will save water in the midst of the worst drought in California history.
On Monday Los Angeles Mayor Eric Garcetti supervised the latest onslaught of 4-inch black plastic balls, bringing the total count to 96 million in the 175-acre reservoir. Located in Sylmar, the reservoir holds up to 3.3 billion gallons, enough to supply the city with drinking water for up to three weeks.
The city says the balls will shade and cool the water, reducing evaporation from the reservoir and making it less susceptible to algae, bacterial growth, and chemical reactions that can produce harmful substances..
