  • JAWRA_ Loss Rates from Lake Powell and their impact on management of the Colorado River_Tom Myers_feb 20, 2013
    • Estimated that more than 14.8 billion cubic meters has been stored in the banks, with a 90% probablility that the value is actually between 11.8 and 18.5 (Gm 3)
    • The Colorado River has 73.4 billion cubic meters of available storage in its 10 largest reservoirs (USBR, 2011), which is approximately four times the river's average annual flow.
    • Lake Powell loses water from the river system in two ways: to evaporation from the free water surface and bank seepage.
    • Bank Seepage is flow to the banks that does not return to the river system whereas bank storage may return to the reservoir or river system.

  • Head water snow melt: 96% of Colorado River water comes from above Lake Mead.
    • 4% tributary input from Lake Mead to Mexico. (2013 MSCP CTR meeting- TMurphy)
