Leg 7, leg 8 and leg 9 of the Transcontinental aqueduct. From the Buffalo Soldier Draw dam to the highest point of the aqueduct 10 miles into Arizona.

Leg 7 is 255 miles. I starts out at 2700′ elevation and ends at 4500′

Leg 7. from Buffalo soldier Draw upper dam to the highest point in Texas

To lift 17,000 cfs of water (4500 – 2700 + 255×2.2) = 2421 feet with a 92% efficiency requires 3.7 GW of power.

Leg 8 is 125 miles. I starts out at 4500′ elevation and ends at 3800′

Leg 7. from the highest point in Texas to crossing the Rio Grande at La Mesa

To release 17,000 cfs of water (4500 – 3800 – 125×2.2) = 425 feet with a 92% efficiency generates 550 MW of power.

Leg 8 is 125 miles. I starts out at 4,500′ elevation and ends at 3,800′

From La Mesa it will climb to the highest pumping station in Arizona, located 10 miles west of the border, at 4,200 feet. The total lift of the water in stage 10 is (4,200 – 3980 + 160×2.2) feet = 572 ft. To lift 17,000 cubic feet per second 592 feet requires 900 MW of power.

The total power needed for these 3 legs of the Transcontinental aqueduct when fully built up is 4.05 GW of power, the bulk of which will be supplied of 40 100 MW LFTR (Liquid Fluoride Thorium Reactors). They are efficient and carbon neutral.

What’s in it for Texas, New Mexico and Arizona? Up to 17,000 cfs of soft water is being delivered to the thirsty south western states. This corresponds to 12 Million Acre-feet per year. The Colorado river contributes 15 MAF/year. The water delivery in the first pass of implementing the Transcontinental Aqueduct is 6,000 MAF per year.
