Many dove hunters seem to think that all that is required for a good dove hunt is some water, any water.
I have seen hunters sitting around a windmill with a concrete water tank in which the water was 3 feet from the lip of the tank. I have also seen hunters hunting around a dirt tank with brush, grass, weeds, and other vegetation growing right up to the edge of the water.
Truth is, neither of those are good places to hunt doves.
Doves require some pretty specific circumstances of their watering holes. First is, they have to be able to actually reach the water, which they could not in the first instance above. Second, they have to feel comfortable and safe.
If a dirt stock tank have brush, grass, and weeds growing up to or even into the edge of the water, the doves are going to avoid it. The greenery is perfect camouflage for predators that like to eat doves. Snakes in particular seem to take advantage of such circumstances.
The best waterholes are those in which the water has receded from the vegetation, leaving a wide strip of clear dirt between the water and the ground cover. If there is no such strip one can be made with a tractor and a rake.
Another good hunting spot is at a windmill which as a leaky water tank. Lots of the older concrete tanks I have seen have cracked or shrunken until they leak a bit, leaving a small, clean pool of water. Assuming the vegetation is not so high as to discourage the doves, the hunting can be surprisingly good in such spots, although not for long, and not continuously.
The same criteria applies to streams as to ponds. If you have access to a small creek with clear dirt banks, the doves will make use of it. All it takes to find such places is a bit of preseason scouting.
