I may have misunderstood your situation, bossone. Are the springs IN the pond or outside and ABOVE the pond? If they're outside the pond and draining into it, that's a great situation and there shouldn't be any issue with the water running back out unless you have a way of altering the laws of physics at your place!

As for next steps, have you proposed a stocking plan for the group's input yet? If not, consider starting a new thread about your stocking ideas and get input on it. I know, and am sure you've seen, that there are some outstanding folks on here who have stocking down to an art form. Always a lot of great advice here. About the only thing I know is that you want to add your forage fish early and give them time to establish a population before you add predators.
What are you doing about structure/habitat in the pond? Are you done adding it, or do you plan to add more? If so, what are you adding? Remember that the type of structure should be fairly well matched to the fish you'll be adding, including your forage fish. Placement is not a haphazard affair, but rather something that should be thought out to ensure maximum benefit. There are a lot of great threads on habitat/structure, so do a search on those.
What other sorts of questions do you have in mind? What issues are you chewing on at this point?
