Getting far off topic here, but Las Vegas is one of the safest water supplies.

There is the often quoted statistic that Las Vegas gets 90% of its water from Lake Mead/Colorado River. But Las Vegas reclaims and recycles 99% of consumed water and pumps it back into the lake via the Lake Mead Wash.

Because they get 99 return-flow credits for every 100 gallons, any draw limits from the watershed will have minimal impact.

Las Vegas also has a large groundwater table that supplies 25% of its peak summer demand.

As a last resort, the Casinos will never let the city run dry. While they only consume 6-7% of the cities water, they depend on their employees being able to live in the city to keep operating.
