In the Wash/Las Vegas Wash Undergoes 12-year, 98 Million dollars Upgrade

摘要

Las Vegas Wash, the carotiod artery of southern Nevada's water supply system, is undergoing a 12-year, 98 million dollars upgrade. Essentially, storm runoff flows into the 14-mi.-long wash, which empties into Lake Mead, the Las Vegas Valley's main source for drinking water. The wash can carry more than 150 million gallons of water daily. Problem is, severe flash floods and neglect have eroded the wash, passing sediment and debris into Lake Mead. "If we don't do something to stabilize the wash, 2.5 million tons of sentiment could erode over the next 20 years," said Neil Laudati, spokesman for the Las Vegas Valley Water District. "That's enough dirt to fill a football field 90 stories tall."
