Assessment of Effects
Inundation caused by the dams has submerged entire cultural resource site areas and limited access to areas of traditional importance. Yearly draw-downs of the reservoirs result in erosion of landforms and deposits that contain artifacts, leaving these areas exposed and subject to looting, vandalism, and unauthorized activities. The Program is able to track these effects by conducting site condition monitoring at some 200 to 400 sites annually. In addition, the Program provides funding for law enforcement officers to monitor sensitive resource areas for any evidence of looting, vandalism, and unauthorized activities.
