The second stage of the aqueduct went from Aquilla Lake to Brad Lake.
The elevation at Brad lake is 1370 feet. From 25 miles East of Breckenridge the aqueduct goes W to 19.5 miles ENE of Abilene, a distance of 60 miles . The dam yet to be built will top out at 1840 feet with maximum water level at 1830 feet. The total lift of the water in stage 3 is (1830 – 1370 + 60×2.2) feet = 592 ft. To lift 26,000 cubic feet per second 592 feet requires two 500 MW LFTR nuclear reactors plus use another 100 MW from the Texas grid. The upper Brad Cemetary dam will contain about 90,000 Acre-ft when full, about two days worth of storage. For 5 hours per day these two reactors can provide 1 GW of peak power to the grid. There will be a lower dam to provide hydroelectric power storage of 4 GWh, of 800 MW for 5 hours, after which the lower dam will be re-emptied by pumping back the water to the upper dam.
And this is what a hydroelectric power storage unit looks like:
