Has Lake Mead dried up yet?

Not yet :-)

A "third straw" has been added (deeper)

"The new intake taps the lake at 860 feet above sea level. That's 190
feet below the tallest existing intake and 218 feet below the lake's
surface level Wednesday.

The reservoir is down 147 feet from when it was at full capacity in
1983. It's currently 38 percent full."
