Figures that demonstrate that the legally agreed-on allocation of water from the Colorado is NOT sustainable:
1928 Boulder Canyon Act:
Allocated 7.5 acre-feet million to upper basin, 7.5 acre-feet million
to lower basin 1944: 1.5 million acre-feet allocated to Mexico 1963 Supreme Court case: 1 million acre-feet allocated to the 5 reservations on the main stem of the river Total legal allocations: 7.5+7.5+1.5+1= 17.5 million acre-feet of water annually. BUT: the Colorado averages only 13 million acre-feet per year (figure based on tree ring analysis.) THEREFORE: The legal allocations are 4.5 million acre-feet greater than the average water production by the river...A HUGE deficit...AND, this does not account for climate change!
