I am wanting to make a small area say 15' wide and 100' long or so that is only 6"-1' deep. I am wanting to run a hose to it and fill it up with water and keep it full. I am doing this to make a watering hole for doves mainly with hopes of hunting around it this fall. I have a lot of farm land around me that the birds feed in but they don't really have a good watering hole so I was going to try this.

No bigger than it is I figure I could just keep the water going to it and keep it full but I was hoping there was some sort of product I could put on the bottom to seal it.

Obviously what I am doing is way different than the large and nice ponds some of you have but I was hoping I could get some ideas on making this thing hold water. Our soil here does not hold water well. There is a hole about 8' deep and 10' in diameter that was dug to bury some old junk in at my place and last year we had a ton of rain and it filled the hole to the top. We did not get 8' of rain but the location of the hole catches a lot of runoff. Anyway it was completely dry in about 4 days.
