MtnLobster....I would quickly get a minnow trap (or a few of 'em) and throw them in the pond & see what you catch. Or try to net something.
I've read some conflicting info. about when certain types of fish spawn. For bluegill, I believe I read that they could spawn any time the water reached a certain temperature.
Those fry you saw could be from some fish that managed to live through the past cycles of your pond. Identifying them would seem to be very valuable to plot the next step.
Smallies all the way!!!!!!!!!! & BTW, great pics of your place.
