Cat:

There's a really good aquafier under ground here. Sandy/gravel/clay bands and all that. The farmers have wells to irrigate their crops, and they're pumping in excess of 200 gpm. I've seen them run 24 hrs a day....

When they turn them on (the closest irrigation tower is within 1/2 mile and the farmer has 5 of them) my pond drops almost 2" per day, and I'll lose up to 4' of water.
