Let's say the West needs a billion gallons an hour, 24/7/365.

You need to build an aqueduct 100 feet wide and 50 feet deep and pump the water at 5 miles per hour. From the Mississippi to CA is about 2,000 miles. Crossing the Rockies and Sierras. Doable but it would prob cost several $Trillion, and operating costs would be ginormous. Plus you would need multiple power plants along the way just to power the pumps.

Ain't gonna happen.
Nobody is proposing this. Only move water a few hundred miles between flooded regions to drought regions, for starters. See how it works and scale up if possible.

This winter's storms are only good for refilling surface water reservoirs. They will not do anything to replenish our aquifers. One of the main reasons for this is that we now direct storm and snow melt flow away from the valleys and to the ocean.
For millions and millions of years, the valleys of California would flood and that water would percolate into the ground creating massive aquifers. As the state's population grew, this seasonal flooding became a nuisance and the people built levees and flood control systems to route this water away from population centers to the ocean. At the same time, agriculture became a big business in the state and farmers had/have rights to the water beneath their land. As demand for fruit and veggies grew, more and more water was pumped from these aquifers to irrigate ever expanding fields, orchards, etc.... The combination of channeling the flow of storm/snow melt water away from the valleys and over pumping for irrigation has exhausted without replenishment what took mother nature millions and millions of years to collect and store. This water will never be replenished as long as we continue on our current path of water resource management.

And there you have it. Not just this winter either, every year there will be more people looking for the good life. California dreaming. I'll be interested to see what happens to the lakes in the Colorado River system, especially Powell and Mead.
