The $0.6B Chimney Hollow Reservoir was self-funded within Colorado, largely by the communities receiving the benefit.
Given the benefits that clearly make winners out of all seven states, perhaps these recipient states (+ ski, mineral and brine shrimp industries) can fund the rapid startup of the Great Salt River without having to rely on Federal funds.
California: immediate new water relief proximal to each of the pumping stations as fresh water is separated from brine: Imperial Valley, San Diego, LA.
Nevada: Southern NV and Las Vegas benefit indirectly in Phase-I
All other CO-River Basin states benefit from the Great Salt River in Phase-II and beyond. Then future spurs can also benefit central NV, AZ, NM,SW ID and TX.
Once the Great Salt River is demonstrated, communities and nations around the world will be clamoring for the water abundance solutions Made in Utah. Utah will be the source of living water to bring peace through community-level energy and water self-sufficiency.
Needed: the courageous and committed philanthropists and politicians who want to leave a legacy, and who are willing to secure the IP to maintain low costs and local / regional economic benefit of the ensuing water infrastructure economy. The below is just a first-pass at a Phase-I funding scenario. Much more feasibility work needs to be done.
The climate will do what the climate will do over the next hundred years.
That's largely out of our hands.
If we have self-powered water in the West, we can make it.
