The third stage was from Brad lake to North of Baird dams (to be constructed).
The elevation at the upper North of Baird dam is 1830 feet. From 19.5 miles ENE of Abilene to the East of Sweetwater dam the distance is 60 miles . The East of Sweetwater dam will top out at 2460 feet with maximum water level at 2450 feet. The total lift of the water in stage 4 is (2450 – 1860 + 60×2.2) feet = 702 ft. To lift 26,000 cubic feet per second 700 feet requires fifteen 100 MW LFTR nuclear reactors The East of Sweetwater dam will contain about 100,000 Acre-ft when full, about two days worth of storage. For 5 hours per day these 15 reactors can provide 1.5 GW of peak power to the grid.
