No, you're talking about Wolf Lake on the state line. That's Hammond, Indiana and whatever/Chicago. The blinds are on the Illinois side. There are tons of wetlands over there surrounded by industry.
When you're on approach about SSW of South Bend headed dead nuts west you'll fly over some wetland areas out in BFE-right over the top of them-I'd say you're between 5 and 10 thousand...that's what I'm guessing. That's the headwaters of the Kankakee watershed and there are lots of ditches...just to the north are two lakes...Upper and Lower Fish Lake. Just west of the wetland area is a decent sized lake marsh south of LaPorte, Indiana. That's Kingsbury Fish and Wildlife area which should be easy to make out because it used to be Kingsbury Ordinance Plant which was a bomb factory so there are lots of bunkers and buildings seperated into a linear pattern. The marsh to the east is a satellite property. LaPorte should stick out like a sore thumb because there are lakes all over town.
