Long term, it was actually meant to bring them in to compliance with EPA regs. They started doing it back in '08, and all the news coverage was of the final dump. "the $250M in "savings" that the politicians are claiming" is the cost of buying an actual cover for the entire reservoir..

The EPA requires LADWP to cover, replace or take offline all of its open-air reservoirs and with the expansive surface of the LA reservoir, it was not practical or possible to use a single floating cover to meet the water quality standards.

Instead of splitting the reservoir in two with a bisecting dam and installing two floating covers that would have cost more than $300 million, LADWP used the 4-inch black plastic balls that cost 36 cents each to meets its regulation standards.

"The shade balls require no construction, parts, labor or maintenance aside from the occasional rotation," the LADWP press release said.
