Leg 4 of the Transcontinental aqueduct is 15 miles of lake and 100 miles of aqueduct.
The elevation at Lake Ray Roberts is 625 feet. From here the aqueduct goes WSW to the Brad dam. It crosses the Brazos river, but does not interfere with it. (This can change if desired). The Brad dam is located just south of the Brad Cemetery on U.S. route 180, 25 miles East of Breckenridge. The dam, yet to be built will top out at 1280 feet with maximum water level at 1270 feet. The total lift of the water in stage 2 is (1,260 – 625 + 100×2) feet = 835 ft. To lift 22,000 cubic feet per second 835 feet requires seventeen 100 MW LFTR nuclear reactors. Lake Brad will contain about 60,000 Acre-ft when full, about one and a half day’s worth of storage. For 5 hours per day these 17 reactors can provide 1.7 GW of peak power to the grid. (The power can also partly be provided by wind power, during which time the LFTR’s can make hydrogen for extra peak power storage).
What’s in it for Texas? The 1.7 GW of Nuclear power can provide virtual hydro-power generation by not pumping water for up to 5 hours and thus provide 8.5 GWh of peak power daily. This has to be done in conjunction with Leg 3.
