Dairy, for which you need green, moisture-rich grass with lots of nutrients.

For the first time I can ever remember, we're treating the water that comes out of our taps. A lot of us won't actually drink it as a result - you can taste the chlorine. But the water table is pretty high in the city, mostly due to liquefaction. And the concern is that broken sewage pipes may have contaminated it. Further out though, a lot of the rivers are pretty low at the moment. I wouldn't be surprised if the Greendale fault has shifted some of the underground rivers, because that cut a pretty wide swath across the countryside.
