Water cutbacks in 2016 are expected to occur for two U.S. western states, Arizona and Nevada. Lake Mead supplies water to roughly 40 million people and agricultural customers in Nevada, Arizona, Southern California and northern Mexico. About 96 percent of the water in Lake Mead is from melted snow that falls in Colorado, Utah, New Mexico and Wyoming. Water managers are concerned about the prolonged severe drought. Their efforts are pointed to conservation solutions. Lake Mead provides also many types of recreation to locals and visitors. Boating, fishing, water skiing, swimming and sunbathing are common activities in the area. As a result of the decreasing water level, marinas and boat launch ramps have either had to be relocated to another area of the lake or have closed down permanently.
