What is being done? Channel stabilization: "Over the past 40 years, erosion has destabilized the Wash channel and caused increased sedimentation in Lake Mead. The Comprehensive Adaptive Management Plan developed by the Las Vegas Wash Coordination Committee (LVWCC) identifies stabilizing the Wash as one of three key initial steps needed for long-term management of the Las Vegas Wash. As a result, the LVWCC has developed the Las Vegas Wash Capital Improvements Plan, which will help to stabilize the channel over the years. One way to deal with erosion is by placing erosion control structures (which are also known as grade control structures or weirs) throughout the Wash. As we succeed in stabilizing sections of the channel, we develop additional riparian and wetland habitat. The erosion control structures help slow the water, creating a pond behind the structures in which wetland plants can establish. Weir construction activities also clear acres of invasive plants such as tamarisk from the banks of the Wash. These cleared areas are then revegetated with native wetland, riparian, and upland species."
