To save water, an underground movement to bank El Niño's rainfall

> The cheapest method of recharge

Is not to use more water from underground than flows back.

The cheapest method of recharge in California is to start buying up farms and shutting them down.

California subsidized putting farms in the Central Valley; it can subsidize taking them back out.

India is doing something similar on a village scale?

This sounds somewhat like Keyline Design (https://en.wikipedia.org/wiki/Keyline_design) a technique developed in Australia to slow water down, minimize runoff, and maximize water infiltration into the ground.

The primary tool is a Keyline Plow or just a standard subsoiler. You simply rip lines slightly off contour based on a "key point" on the topography. This encourages water to flow laterally across the hill from the wet valleys to dry ridge lines, slowing and soaking in the water rather than flowing straight down hill and causing erosion.

Pretty much every farm and ranch should be doing this - but on a direct local scale on each piece of property rather than yet another public works project.

This is basically more public money being used to supply the multibillionaire multi-national farmers of California with more free groundwater to extract and use for their profit (and yes, there are studies showing that most water is used by farmers, and that multi-nationals control the bulk of California farmland - even though 80% of farmers are small, they don't control most of the water and most of the land.)

Is the bank underground? Is the movement underground? So many questions.

After reading, it seems like the movement is underground, the water banks are above ground.

Sounds good until Nevada does it.
