Leg 12 of the Transcontinental aqueduct is complicated. The total length of this segment is 105 miles, 20 miles is a 6,200 cfs aqueduct, and 85 miles is the Gila River. This map may help explain it:
But there is a problem that must be solved. Gila River is now mostly dry, and goes through an Indian reservation. The Gila River used to provide about 1.3 Million Acre-ft per year, snow-melt and monsoon rains providing nearly all of it, but was seasonally dry. Now all the water and then some is spoken for, so the Indians get nothing, and without water you can do no farming, so the reserve is largely depopulated. See map:
In Phase 1, the Gila River will free flow. In Phase 2 there will be a55 mile aqueduct thru the Indian reserve dimensioned for 10,000 cfs flow. It will provide some power with a drop of over 400 feet. The maps will look like this:
Total power required for Leg 12 is 160 MW for phase 1 and 320 MW for Phase 2. Since it is continuous it is best served by three 100 MW LFTR reactors.
In Phase 2 the CAP aqueduct will be replaced by one that flows from east to west, and the Mark Wilmer pumping station will be converted to the Mark Wilmer generating station with the same capacity. Electricity generated will be 16% less than the energy that used to be consumed to pump up the water.
What is in it for Arizona? The Greater Phoenix area will get an increased water supply from the canal,since Tucson is already served in Leg 11. The Gila Indian reserve will get back the water supply that was taken away from them, a way of reparation, and will again make the Gila Indian reserve a viable community.
