Funky, The link below is a big PDF file of fish stockers in MI (some are fee fishing locations only) The one in Kent County is not far from me but has shut down long ago so some of the data on this PDF may be outdated.
The easy way to find things is open this PDF, hit Control-F for search and type tilapia. it will jump to the first tilapia, then hit enter again and it will jump down to the next one etc.
I found several, one is in Fowlerville which may not be far from you. Also Detroit, Walled Lake, etc.
