Leg 6 of the Trans-Rocky-Mountain aqueduct. From Trinidad Lake to Abiquiu Reservoir.

Leg 6 of the Trans-Rocky-Mountain aqueduct. From Trinidad Lake to Abiquiu Reservoir, a distance of 90 miles.

Lake Trinidad, elevation 6230′ Water storage 100,000 acre-ft

From Lake Trinidad the aqueduct will carry up to 10,000 cfs.

Elevation 6270′ Water storage 200,000 acre-ft, max. capacity 1,369,000 acre-ft.

The aqueduct will start at Lake Trinidad and follow the river up to Stonewall, where from an elevation of 8450′ it will tunnel under the Rocky Mountains for 7.5 miles and exit 3 miles s.e. of Chama.

From there it will be finding best way to the Rio Grande Canyon, where a dam with culverts for Rio Grande will be built at an elevation of 7490′. The canyon may or may not be a reservoir, dependent on the wishes of the local community. There will be a provision for supplying Rio Grande with some water during the growth season. On the West side of Rio Grande it will gently descend to 6000′, but with occasional rises of up to 100′ . Finally it will climb 270′ to Abiquiu Lake. There will be a provision to supply the river with water , especially during the dry summer. The total climbs for this leg is (8450 – 6230 + 150 + 270)’, plus the 2feet drop per mile times 25 miles. This comes to 2690′. The power required to pump 10,000 cfs 2690feet is 2.4 GW, assuming 92% pumping efficiency. Some of the power is regained on the downhill part, Total downhill is (8450 – 6000 + 100)’ = 2550′ minus the 2feet drop per mile times 65 miles. This comes to 2420′ Power regained from 10,000 cfs dropping 2420′ is 1.8 GW assuming 92% generating efficiency. The total power requirement for this leg is 600 MW. This can best be provided by having 6 100MW Liquid Fluoride Thorium Reactors, they are carbon neutral. The reason for small reactors is that they can be built in assembly line fashion and the core reactor can be shipped on a flatbed truck. The reactors will provide power to pump as much water as needed, but will stop pumping water when peak power is needed and start acting as a virtual hydro-storage. For this leg seepage and evaporation losses will be less than 2%.
