I do like the concept of a warmouth pond!
A potential forage fish for larger gamefish (in other people's ponds), but also fun to catch for kids in their own right.
I assume FHMs to start, but what are you going to use as the long-term food source for the warmouth?
Are you going to control their numbers by angling? Don't you have a buddy that is a fly fisherman? That might be a good way to sample your warmouth population, and then manage as needed.
I look forward to some of your future posts on this pond.
