SAND TRANSPORT caused by 2012 HFE

  • @ RM30 = 390,000 metric tons
  • @ RM60 = 380,000 metric tons
  • @ RM87 = 540,000 metric tons
  • @ RM225 = 970,000 metric tons
  • At Diamond Creek (RM225), 1,810,000 metric tons were transported by the Colorado River between July 1, 2012, and July 1, 2013. Thus, 54% of the total delivery of sand to Lake Mead reservoir during this 1-year period occurred during approximately 5 days of the November 2012 HFE. For comparison, 45% of the total delivery of sand to Lake Mead reservoir during calendar year 2008 occurred during the 2008 HFE; the 2004 HFE delivered 40% of the total sand delivered to Lake Mead in calendar year 2004.
