It depends on the farm, and the size of it. This year was so bad I seen smaller farms using firetrucks to try and flood their fields and get water to them. I think most farms (depending on how late they got their crops in) only produced 40% or less. And alot of them just combined it up for compost and are hoping to make it up next year, so a total loss for some of them. So I assume they are David vs Goliath against the insurance companies trying to recoup some money.
My well is 330ft deep, and I live close to a natural spring. My well was sending up mud water in my faucets, and my cistern (for those that dont know its rainwater collected by gutters, at my place anyways) was completely dry. Its 1000 gallons. We got hit hard this year by no rain, then right as the farms were getting reading to harvest the 3 or 4 plants they had, it monsooned and ruined rotted alot of the corn and beans off the stalks before it dried up enough. This year was a complete disaster.
