Congrats on the new property. It sounds fabulous!
What are your goals for the ponds?
It does sound like you are set up for trout, but if that is not your preference then you could set up the ponds for many other combinations of fish.
How were the ponds capable of sustaining a current? Were they spring-fed, or was water diverted from the creek at some higher elevation?
Good luck on the future development of your ponds and your property. That should be a very enjoyable adventure.
