Chip, I can tell you for an absolute fact that the idiotic Federal court ruling, precluding the diversion of surface water into irrigation reservoirs in Central California because of danger to the Delta smelt, is destroying millions of acres of productive farmland.
Prior to this ruling, run-off was directed into reservoirs in Central California that served an estimated 22 million Californians, and most notably, thousands of farmers tilling millions of acres.
"Because of this ruling, in 2009 and 2010
more than 300 billion gallons (or 1 million acre-feet) of water were diverted away from farmers in the Central Valley and into the San Francisco Bay – eventually going out into the Pacific Ocean."

I drive through central California to visit family in Sacramento, and the effect is noticeable to the naked eye. Central California was very recently populated with thriving small communities, dependent on farming in that area.
Now, those Central California towns - Hanford, Visalia, Kettleman City, Lost Hills - have greatly reduced populations and employment due to the loss of the most important economic factor in the area: the farms in the Central Valley.
Those farms used to produce produce lettuce, corn, asparagus, broccoli, turnips, radishes, peaches, apples, almonds, and on and on. The farmers also hired laborers to pick the crops, drivers to transport the crops, supervisors to schedule the work shifts and deliveries, bookkeepers to keep track of product and billing. That business also generated the tax base used for roads, schools, fire departments, and police.
Now the farmers don't have the water to remain in business. The towns have shrunk, and quite a few of the businesses in these towns are boarded up.
But hey, who cares, right? Just a bunch of redneck farmers are out of business. It's not like this policy adversely affects Harvard.
