Lots of money for little water….

It took $817 million, two starts, more than six years and one worker’s life to drill a so-called “Third Straw” to make sure glittery casinos and sprawling suburbs of Las Vegas can keep getting drinking water from near the bottom of drought-stricken Lake Mead.

The pipeline, however, won’t drain the largest Colorado River reservoir any faster. It’s designed to ensure that Las Vegas can still get water if the lake surface drops below two existing supply intakes.
