The fourth stage was from North of Baird dams (to be constructed) to East of Sweetwater dam (to be constructed
The elevation at the East of Sweetwater dam is 2450 feet. From the East of Sweetwater dam to the Grasslands Canyon Lake the distance is 50 miles . The Grasslands Canyon lake will top out at 2800 feet with maximum water level at 2790 feet. The total lift of the water in stage 5 is (2790 – 2450 + 50×2.2) feet = 450 ft. To lift 26,000 cubic feet per second 450 feet requires ten 100 MW LFTR nuclear reactors. The EGrasslands Canyon Lake will contain about 110,000 Acre-ft when full, more than two days worth of storage. For 5 hours per day these ten reactors can provide 1.0 GW of peak power to the grid.
