it would not be necessary to dig a well. All you would need to do is set a guage stick in the pond and then if you can raise the level by pumping you know that you are holding back most of the flow of ground water into the pond. Depending on the permeability, it may be difficult to raise the water level by much. Either approach could provide information about the feasibility but with esshups suggestion you could determine whether it would be worthwhile to purchase a pump. How much land do you have? is there much elevation drop through it? If enough, you could build a well pond and install aeration to precipate the iron and then drain the cleaner water (after iron precipitated) to the larger pond. There would have to be difference in the ground water elevation of the well pond. It would have to be higher in elevation in order for it to gravity to the other. But if the flow was sufficient ... it might be enough to overcome inflow. Organics like leaves and such could help with forming a liner that would be stable if the flows into pond were sufficient. The pond is going to leak into the soil if its water elevation is higher than the local table ... so I am only talking about slowing the leaking sufficiently to allow the positive pressure in the pond relative to the table. Organics like cow manures are used in many parts of the world to slow filtration in fish production ponds. I have even used crumbled cow manure to slow leakage in an auto coolant system.
