Calling all engineers! Would it be possible to make a continuous, running loop out of my stream?

On our land we have about a 1 acre pond. It is so very cool. It’s surrounded by a U shaped earthen dam. The dam starts on the north west corner and runs around the west, south, and east side of the pond to the north east corner. The north end has no damn.
When it floods, like it is now, there is a natural outlet on the south east corner, a stream that takes the overflow and runs around at behind the dam on the south side, and diverts it to other areas to the south and west (not sure exactly what other areas. It’s not controlled yet. I think, basically, the south side of the property just gets soggy.) This is good because it keeps the area to the north, where we want to build the house, free from flooding.
When the stream is running it is so pleasant to see and hear. The water gurgles over rocks and stuff. But it only runs when the pond is flooded.
I would like to widen and deepen the stream and engineer it so that it runs in a continuous loop from the south east side and flows back into the pond at some point, so that we always have a running stream.
It would have to be engineered so that if the water got too high, as in a flood situation like we’re in now, the over flow from the stream would be diverted to the ditch that will eventually be running along the road to the west of the property, so the north end doesn’t flood. I think that would be easy enough to do if we install a culvert at a certain height, so if the water gets that high it flows into the ditch.
As for a continuous flow….how could we do this?
