There is a small water hole I am hunting by right now and to keep it filled I have a plastic 55 gallon drum with a nozzel and piece of hose, works like a charm and the drum empties in about two minutes. I dont use a pump either, just let gravity do the work.
That's a good idea. Another idea that I've seen, and can't find a link to right now,involved making an artificial watering hole that uses steel siding angled towards the water collector.
