This story seems to almost be out of science fiction (or The Prisoner) but the pictures don't lie. The water people in Los Angeles are so desperate to save what water is left in some reservoirs that they are essentially putting a roof on it by filling the lakes with black plastic balls:

Facing a long-term water crisis, officials concerned with preserving a reservoir in Los Angeles hatched a plan: They would combat four years of drought with 96 million plastic balls.

On Monday, Mayor Eric Garcetti of Los Angeles arrived at the 175-acre Los Angeles Reservoir to release the final installment of the project: 20,000 small black orbs that would float atop the water. [...]

Mr. Garcetti said that the dark balls would help block sunlight and UV rays that promote algae growth, which would help keep the city's drinking water safe. Officials also said the balls would help slow the rate of evaporation, which drains the water supply of about 300 million gallons a year. The balls cost $0.36 each and are part of a $34.5 million initiative to protect the water supply.

This is an ingenious way of reducing evaporation. Perhaps the state's aqueduct system can also be filled with these balls to stop evaporation there.

    Water surface is never in shadow (except at the edge). Sun's UV are lethal to most microbial life, and only specialized organisms can live on water surface. So generating shadow can lead to complete change of what organisms will live there. Probably all sun-liking microbes will die and be replaced by shadow-liking ones. Let's see what effect this will have on our health and entire ecosystem.

    Well obviously the dark-side midichlorians will win from the light-side midichlorians, but they were wussies anyway. I can't wait to try my new Californian Force Lightning™ after drinking Dark Water™.

    They discussed that on CBS news. The balls prevent algae from growing, and algae releases toxins.
