As it applies to what we do, hunting one individual buck over water is a tough prospect. Hunting water is fun but if you have one particular buck you want to shoot, its a shot in the dark. From what I have learned hunting the desert, bucks can and will go three days without water. Couple that with a guzzler every 2 miles and dirtranks in between and one deer could be anywhere.
Now, if you want good action and you want to see alot of deer, find a good water hole off by itself and hunt it. The cool thing about water is you never know what is going to come in. Its kind of like deep sea fishing, you never ever know exactly what is going to come up. The only exception to what I'm saying is if you have a buck in a good solid summer pattern and he's feeding in the same area every night or (like others have said) he feels very safe at the water hole hes using. But once those bucks go hard horned, they get goofy and can be anywhere any given day, thats how they survive.
