Where Does LV Receive Water? The state of Nevada is allocated 300,000 acre-feet of water from the Colorado River annually, which is only 2% of the river’s output This measurement was designated by President Hoover in 1922 when the population was 4 thousand, and Las Vegas’ current population is 2 million people The Las Vegas area receives 90% of their water from the CO River reservoir in Lake Mead

Water Issues Las Vegas is the fastest growing metropolitan area In the US with a population of 2 million people with 36 million annual visitors In 2005, the water supply ran out for the first time Las Vegas uses between 2 and 3 times the amount of water per person per day compared to other cities of its size. 92% of Las Vegas’ water is used by residential homes Scientists predict devastating effects from global warming on the water supply. “They really all see, as do most scientists, the fact that we’re not really in a period of drought. It’s climate change.” – Dr. Stephen Parker, UNLV Thus, these water issues may not be strictly conservation issues

Pipelines to Hydration Las Vegas needs 200,000 acre-feet more water than allotted from the CO River. A proposed solution is an underground pipeline 300 miles away to basins in Baker, Ca. that flow into Lake Mead Currently, the Southern Nevada Water Association is trying to secure access to these basins and purchase the farms that are dependent on the basins. Residents and farm owners in Baker are opposed to these purchases for reasons ranging from the effects the pipeline will have on wildlife, residential life, fishing conditions, to tourism and aesthetic value Pat Mulroy, the SNWA General Manager states, “This pipeline is critical to the survival of Las Vegas.” Las Vegas will not cease its population growth and the extra water is not longer a luxury, but a necessity.

Las Vegas Strip Many people question the large amounts of water occupying various hotels and attractions on the Las Vegas Strip. Las Vegas is an entertainment capital that has gone to great lengths to become more efficient hydraulically. The attractions on the Strip use recycled water. The total water used, including water evaporation only uses 8% of the entire counties water supply The water is used in pools and various water shows that attract over 38 million tourists each year. The strip accounts for 70% of the entire state of Nevada’s gross product The Strip has also removed hundreds of acres of turn requiring water with faux turf or desert landscaping, cutting down on their already low water consumption Without the visitation the strip gets, the state of Nevada would not survive according to Richard Bunker, CO River Commissioner The water used on the strip would not bring in the revenue it does if it were focused on crops such as alfalfa and other crops. In conclusion, Nevada cannot afford to NOT water the strip

Conservation Efforts While the water issues Las Vegas faces may not be 100% manageable by conservation, they certainly will not hurt. Doug Bennet, a conservation manager for the SNWA has implemented an incentive program for those who practice residential water conservation Las Vegas residents must follow a lawn watering schedule and are encouraged to eliminate grass and other plants and replace their lawns with desert landscaping. The county has hired patrol agents to check for water waste in residential neighborhoods Las Vegas has started a water treatment program that drips water back into Lake Mead for return flow credit. “There is more that can be done in conservation if they want to do it. But it’s not the gold or silver bullet that will solve our problems.” – Richard Bunker
