When you consider that at least 3 large metropolitan areas - Las Vegas, Salt Lake and the Los Angeles megalopolis depend in part on this area for their water supply makes you scratch your head.
I'm sure scratchin mine. I was pretty sure that LA water comes from the Eastern Sierra, and Vegas with a population about 1/20th of LA, from the Colorado River i.e. central Rockies. Salt Lake, which is about 1/50th the population of LA County, gets its water largely from the Wasatch. None of these sources are in the Great Basin.
