This is more of a curiosity question: Running water from my well to the pond just through a 1” pipe to keep it from dropping too low this summer. I’m noticing large schools of the smaller fhm and other fry all trying to get right into the middle of the outflow/high current area. Is this some spawning reflex trying to go upstream? Something in the well water they like? I always assumed the well water was oxygen low but?? Thoughts?

Getting into a current is a migration / population expansion instinct. In nature, a current frequently leads to another body of water that they could expand to. If a pond floods, some fish will attempt to follow the inflow or outflow.
