2. Case Study: Monitoring And Protecting Water Quality In Lake Mead, Nevada
   8/29/2006
   Lake Mead is one of several reservoirs along the Colorado River; however, due to increases in population and agricultural operations in recent decades, this once-expansive lake in the desert is becoming more compromised. While inflow into Lake Mead primarily is from the Colorado River, a small percent is also from rivers on the northern side of the Lake and from Las Vegas Wash on the northwest side. Las Vegas Wash transports treated municipal wastewater effluent, stormwater and urban runoff, and shallow groundwater seepage from the Las Vegas urban area to Boulder Basin in Lake Mead. Effluent flow rates have more than doubled in recent years, prompting concern over potential effects to reservoir water quality, especially since some of the water is pumped for the municipal water treatment plant at Saddle Island
