A new report out this week shows that Californians are finally getting the message about water conservation. Sort of. 

Three years into a severe drought, we're finally tapering back on water use.

Compared with last summer, residents slashed how much they used by 7.5 percent.

That's good, but nowhere near the 20 percent Governor Brown called for earlier this year to cope with the drought. 

Lester Snow, executive director of the California Water Foundation, explains what more Southern California residents can do when, historically, they already have some of the lowest per capita use of water in the state.
