Leg 7 of the Trans-Rocky-Mountain aqueduct. From the Abiquiu Reservoir to the San Juan River, a distance of 55 miles.
After delivering some water to Rio Grande and other drop off points, the sixth leg has a capacity of 8500 cfs. It starts out at 6270′ and climbs to 7400′ over a distance of 25 miles. This requires a maximum power of (7400-6270 + 2x 25) = 1180′ times 8500 cfs. Assuming a pump efficiency of 92% this comes to a power of 900 MW. From the top it then descends to 5590′ over 30 miles. This will generate a power of (7400-5590 – 2x 30) = 1750′ times 8500 cfs. With generator efficiency of 92% this comes to 1,100 MW. This last leg will generate up to 200 MW power, thus reducing the total power need for the aqueduct.
Once joining the San Juan River there may be some levies put in to protect the people having built their homes in the flood plain. The river once was unregulated and subject to seasonal floods, and periods of very low flood, but once the San Juan Reservoir was built, the ecology of the river changed drastically. The addition of the aqueduct’s water would further stabilize the flow, but not add to the risk of seasonal floods.
The San Juan River would then add a maximum of 8,500 cfs. of water to the Colorado River, but especially during the summer months much water will be delivered en route to thirsty communities, such as Albuquerque and even Santa Fé, and some water will help the greening of the surroundings of the aqueduct and even save aquifers, especially the Ogallala aquifer, so the real average flow will be more like 5,000 cfs. This will translate to an additional yearly inflow of 3.6 million acre-feet into the Colorado River.
Leg 6 of the Trans-Rocky-Mountain aqueduct. From Trinidad Lake to Abiquiu Reservoir, a distance of 90 miles.
From Lake Trinidad the aqueduct will carry up to 10,000 cfs.
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%.
