Questions about invasive species

I fish SE Michigan and LsC pretty regularly and I know we have the invasive round gobies which I've caught a good amount in the big water but I'm starting to see them a lot more in the feeder creeks and small rivers running into LsC especially from the north end and the thumb.

Has anyone else here seen them in the creeks and streams in the thumb and in what size and quantity and have you reported them to the DNR/state of Michigan and what has been the result s of your findings?
