LA gets blackballed (actually, it's just water)
Lexile

Los Angeles has been blackballed.
 
The city has completed a program of covering open-air reservoirs with floating "shade balls" to protect water quality.
 
City officials have dumped the last 20,000 of 96 million black balls into the Los Angeles Reservoir. It's located in Sylmar, 25 miles northwest of downtown.
 
The 4-inch-diameter plastic balls block sunlight from penetrating the 175-acre surface of the reservoir.
 
That prevents chemical reactions that can cause algae blooms and other problems. And it allows the Department of Water and Power to meet U.S. Environmental Protection Agency water-quality requirements.
 
The balls have the added perk of aiding with the ravages of the drought. They are expected to keep about 300 million gallons annually from evaporating.
 
"In the midst of California's historic drought, it takes bold ingenuity to maximize my goals for water conservation," Mayor Eric Garcetti said in a statement. He noted that the effort is "emblematic of the kind of the creative thinking we need to meet those challenges."
 
The 36-cent balls also will help prevent evaporation of 300 million gallons of water annually from the 3.3 billion-gallon reservoir, the DWP said.
 
The city began using shade balls in 2008, and they now also cover the Upper Stone, Elysian and Ivanhoe reservoirs.

    The black balls conserve water by reflecting the sunlight so the reservoir doesn't evaporate and the water stays.

    They stop algae from growing and other problems happening. So the water is fresher and doesn't grow bad stuff.

    I think that the program helped the water quality a lot. People lost hundreds of millions gallons of water. They are putting the shade balls in unenclosed water reservoirs to block the sun a little and improve the water quality. I think that the loss is so bad but the system can help them even a little bit.

    The black balls conserve water by blocking the sunlight so the water doesn't evaporate, as said in the 6th paragraph. This article interested me because I thought it would cost way more money than it does to make these balls.

    I think that the LA gets blackballed Idea will work. The city’s officials dumped 96 million 4 inch black balls into the Los Angeles Reservoir. They did it to protect the water from algae blooms and other problems. It also helps to save 300 million gallons of water to evaporate. The city began to use the balls in 2008 and they now cover the Upper Stone, Elysian, and Ivanhoe Reservoirs.

    I think this is very creative to help save water. I hope the black balls help conserve water.If this all doesn't work all of this is a waste.These balls could cause many problems. Such as swimming and boating activites.

    I think the black balls idea is a perfect idea. It will Help extremely by saving water while going through this year round drought. Even though LA will still be loosing water they wont loose as much as before. They were first put in Upper Stone, Elysian, and Ivanhoe reservoirs in 2008 and helped. Also a good use of knowledge and science put in to create these balls.

    The 4’ diameter plastics balls protect the sunlight from penetrating the 175-acre surface of the reservoir. The plastics balls could help save 300 million gallons of water a year.

    The black balls conserve water because when its covering the water, it doesn't evaporate as quickly so plenty of water is saved.
