Glen Canyon Dam Lake Powell 

During October 2011 the unregulated inflow volume to Lake Powell was 575 thousand acre feet (kaf) which is 105% of average.  This was approximately 75 kaf below what was projected in the October 24-Month Study and resulted in the elevation of Lake Powell ending October about 1.26 feet below what was projected in the October 24-Month Study.  The October 31th, 2011 elevation of Lake Powell was 3650.27 feet above sea level which corresponds to a live storage of approximately 17.25 million acre feet (maf) and 70.9% of the full capacity of 24.32 maf.
