Keep in mind that digging below(or anywhere around) a dormant/non-surfacing spring may expose the water flow again. I think this is where Fish N Chips was going when he refers to hitting some vein. I'm no expert, but I would certainly be concerned about putting a pond around a spring, dormant or not. You might end up with a nice inflow for the pond OR you might end up with a drain vein in the bottom. Things for you to learn about, maybe even do some exploratory dirt work. +1 on fish n chips advice regarding talking this over with your pond builder.


Fish on!,
