So if we want a real, helpful infrastructure project, why not a water pipeline to end ag and urban droughts in most of the western states? Desalination plants in Texas, a network of pipelines/?aquifers? to perhaps central Colorado so it can feed the western Colorado, Rio Grande, Pecos, TX Colorado, Brazos, Red, Arkansas, and Platte River watersheds. Solving the water issues for CA, NV, UT, CO, NE, MO, and every state south of them. Guaranteed capacity for full planting allocations every year, no more drought restrictions on residents, full reservoirs, and optimal stream flows to satisfy environmentalists (though by nature the activists will never be satisfied. But can help with reducing court challenges to future projects across the board.) No more wasting valuable land by building new lakes and the environmental impacts of them. The Gulf of Mexico becomes the reservoir with the capacity to handle all future growth.
Yes, that's a hell of a lot of pumping to reach the western Colorado and the Front Range cities, so short term perhaps not cost effective. But ultimately would provide national ag security and remove a huge growth issue for western cities. (Of note, western cities and suburbs are usually much more efficient, they tend to develop more contiguous and densely compared to back east. Saw a stat years ago that DFW was 3 times as densely developed as Atlanta.) No more poor crops because of drought, only have to worry about the years with too much rain. Long term has the potential to open up more land for ag use if at some point in the future our demand requires it, so a national security guarantee.
Not sure how much of pipeline capacity could be reduced by shifting reservoir allocations or if it is possible to fill near ends of some aquifers and increase pumping from the far ends. I don't know the flows, but seems like there would be a way to refill the Ogallala aquifer. That could allow for reallocations and perhaps other gap pipelines to additional watersheds or aquifers that might benefit all the way up to the Dakotas.
A long-term Fed project that wouldn't have a short term increase in inflation, because the planning and enviro review process would take many years. Would need federal coordination and partial funding, but could figure out a formula for taxing future development in the affected states to repay the feds. Heck, capture the reduced ag insurance costs from removal of the drought threat.
The US doesn't have a long term drought problem, it's just an issue of cost and political will. I'm not the first to propose this. We can choose to start now, or keep kicking the can down the road.
