In actuality, the Central valley is much more complex. The soil there is so bad that in many places it is covered with a layer of salt that cracks when you walk on it, much like a thin layer of ice cracking under your feet.

The Central Valley is also the most productive agricultural area in the world.

In order to farm land in the Central Valley, one has to install rows of leach lines about 4'-5' underground. The land is then diked on all four sides and flooded. The water rinses all the bad stuff from the soil, into the leach lines and out and away. The land is then good for growing.

The water in the Central Valley is actually quite good.
