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)
