[null and void]

The water comes from 400 miles north from a river called the feather river.

Part of the year, the rest of the year it comes from the Colorado River.

There is a subtle difference between the supply that is able to make it past the water filtration systems and temporarily crash the yield in semiconductor manufacturing. I got in considerable trouble when I warned my boss to expect a 2 week yield crash when they switched. He kicked me out of his office when I made the prediction. Then called me on the carpet to explain what I did to cause the crash, and called me a liar to my face when I told him how I knew it was coming.

(He did call me years later to apologize when he realized it was true)...

Ah...the happiness of chip manufacturing. We detected seasonal yield variations at our Houston site. We still hadn’t figured it out when I retired at the end of 1994.
