The Las Vegas Wash (LVW) carries more than 170 million gallons of water a day.

Decades ago, the flows of the LVW created more than 2,000 acres of wetlands.

By the 1990’s, only about 200 acres of wetlands remained.

The dramatic loss of vegetation reduced both the LVW’s ability

to support wildlife and serve as a natural filer for water that flows to Lake Mead, the source of our community’s water supply.

The Southern Nevada Water Authority (SNWA) has been conducting archaeological investigations in the Clark County Wetlands Park for many years.

Due to the patchwork of identified culturally significant sites throughout the Clark County Wetlands Park, combined with several projects to develop the area for recreation and erosion control activities, the Bureau of Reclamation (Reclamation) has developed and executed the Cultural Resources Programmatic Agreement (Programmatic Agreement) in an effort to facilitate the planning, permitting and implementation of these projects.

This Programmatic Agreement creates a partnership between Reclamation, the U. S. Army Corps of Engineers, the Advisory Council on Historic Preservation, the Nevada State Historic Preservation Officer, Clark County, Nevada, and the SNWA.

Activities conducted for this proposal should generally meet National Historic Preservation Act consultation requirements.

This proposal is a priority for the comprehensive management of the LVW because it helps the SNWA meet action items in the Las Vegas Wash Comprehensive Adaptive Management Plan (LVWCAMP).

This proposal is intended to help meet the following LVWCAMP action items:
• Action Item 1 - Install erosion control structures • Action Item 37 - Ensure implementation of mitigation measures • Action Item 41 - Conduct additional research • Action Item 42 - Preserve and address cultural resource issues
