What species live in the stream now? You're best to keep just them.

Sounds like you want fish to come up during feeding time? Koi and Sturgeon. Just fortify the narrow outlet. You mentioned grate but with experiences of others, Muskies and Pike are able to escape. So how bout netting and quarantine area where if the fish were to bypass 1st barrier, they would be trapped in 2nd cell area?But if my native options are channel catfish, channel catfish, or a channel catfish, then forget it. I'm getting something worth coming home to.
And it's still not a closed system. There was beaver dams, man-made dams and culverts in the creek from the fish hatchery to the lake. Also I think you forget the non-native diseases or worse....the pond fish spawned and have fry.Sounds like you want fish to come up during feeding time? Koi and Sturgeon.

.....so it is very risky to stocking non-native species in a stream-fed pond but the decision is up to you as long as you are take responsibility for let non-native species escaped or introduced exotic pathogens to the area.
And I'm hoping that he will take ALL of the responsibility for let the non-native species escaped then he will have to live with his decision for the rest of his life and should be ashamed for his actions. The last thing the aquarium hobby needs is more restrictions on fish-keeping and making other species illegal to own.like he said, "decison is up to you.."
