We need to improve quality standards in Lake Mead. Most of the lake’s water originates as snowmelt in the Rocky Mountains that flows down the Colorado River. Climate change reduces the amounts of snowpack limiting water supplies. Naturally, this affects the water available. Increased evaporation and ongoing drought conditions worsen the problem. Drought conditions lowered lake levels by more than 150 feet in the region. Consequently, the concentration of contaminants increases.
Nearly 90 percent of the water Las Vegas uses comes from Lake Mead. These factors outlined above result in poor water quality. We need to improve our water quality in the Las Vegas Valley.
