I've hunted and fished across the Midwest for four decades, long enough to form opinions.
Good fishing depends on good water quality.
Good nesting cover and water on the prairies mean more deer or grouse. It's habitat, and if it's in place, you'll find game and birds and fish. I've spent time in legislative halls, tramped streambanks, and launched my boat on countless lakes and reservoirs. Fishing may be better today than it has been at any point in my lifetime. Well, I'm realistic.
