Yes that's correct... It was extremely low...
But it's the highest it's been in many many years... (not sure the exact year, but I think, don't quote me) since the early 80s.
They were saying last year it'd take 11 good winters to get it back up to capacity... I think they've adjusted that to something like 7 after this last winter.
Lake Mead is another lake that California and the South West depends on... and It's up this year as well.
