I can think of four separate instances where GS were the first fish to colonize a pond, all unstocked.
Our fisheries chief thinks that GS are sometimes found in waterways without continuous flow. A short upsteam migration during a rain event, followed by living for a few months in stagnant puddles left behind could be a GS vector.
In our case the lake was built in a cornfield with no bodies of water in the watershed. Interesting that there is no definitive answer.
