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 90 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 + 90×2.2) feet = 538 ft. To lift 26,000 cubic feet per second 538 feet requires two 500 MW LFTR nuclear reactors plus use another 240 MW from the Texas grid. 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 two reactors can provide 1.0 GW of peak power to the grid.
