My pasture is dying early and my garden is parched. I've been watering everyday and I just can't keep up. For the first time, it looks like I am going to lose part of my garden to drought

I've got 25 Rutgers tomato plants that are ripening now, and 40 determinates of different varieties, as well as 500 feet of sweetcorn in various stages of tassel, some probably ripe next week. I've got an additional 350' of corn that's about knee high. I also have a small melon and squash patch that I have been hand watering.
One of my angus/longhorn crosses just keeps staring longingly at the green corn and mooing. If it does not rain soon I'll be pulling up the knee high corn and feeding it to him. This fall I am going to wash in an agricultural well specifically for the garden, orchard and livestock. On the bright side, I have not had to cut grass in a month
