Wild Brookie in an urban creek?

[njmultispecies]

So I have been exploring local ponds, rivers, and streams. So I fished this creek that runs through my town. Threw a trout magnet with no luck or a while. Then, I found some holes with a very healthy population of pumkinseeds and creek chubs. (Some of these creek chubs were above the 7 in mark.) Then I spotted something bigger dart upstream. I thought nothing of it at first, making a cast toward that general area convincing myself it was just another chub and kept fishing. Then I saw it again, this time stopping near me, within eyes view. It was a brookie, a nice one too. Nearly fainted, considering the patterns on the fish and the fact that I was fishing next to a gas station. Casted my trout magnet past him, tried to get a bite and spooked him. Fished for another 30 mins there with no trout. Came back later to fish but didn't see it. Is it possible that there are wild reproducing trout in this creek? Keep in mind it runs past a bunch of stores and businesses and is full of trash Or do you think it was a leftover stockie? Just a little report/story and tight lines.
