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.
500,000 Tons of Sediment
- 500,000 tons of sediment is equivelant to filling a football field 230 feet deep (KSalazar)
Effects on Resources
- Cultural: No adverse effects to historic properties of the 2012 HFE were identified. (USBR Memo 2013)
- HBC & Native Fish:No measuable positive effect on HBC or other native fish. (Provisional- unpublished data)
- RBT Monitoring: RBT in Glen Canyon moved very little during the period around HFE.
