We have springs and or ponds in every pasture. The bigger pastures 100-200 acres, have several ponds. The only piped water we use is in the pens. This is year round for the last 50 plus years with no problems. The problems coming now are that the springs are getting real low and some of them drying up because there has been so much of an explosion in population in our area and there are so many new wells it is lowering the water table. That is getting alot worse and going to cause major headaches. Like Angus said, it would cost hundreds of thousands of dollars to run dig wells and run water lines to all the cattle. When you figure over 30 ponds plus the springs and streams where the cattle water, it would cost a fortune to put in the waterers and also some ponds were hard to get to hold, so if you break the seal, it might not ever hold again. After watering this way and never having a problem, it is hard to justify spending a huge amount of money to fix something not broken. Also those waterers take some time and money for upkeep, I have never seen on that a neighbor wasnt having trouble with at one time or another. It may be foolish, but every time I hear one of them complain about having to dig out or fix a waterer, I just think, there is way too much to do than to spend a minute messing with a waterer.
