I think Alan is right on the mark with his ID's. The larger dead
shell does indeed appear to be Strophitus undulatus
http://www.inhs.uiuc.edu/cbd/musselmanual/page82_3.html Without an
inside photo to see the hinge line I wouldn't bet the farm on it, but
I would be will to go a six-pack.
The second photo is of a live Corbicula fluminea or whatever we are
calling the Midwestern invasive these days.
The third group is a mix of Corbicula (top row left and the two on
the right in the bottom row)
http://www.inhs.uiuc.edu/cbd/musselmanual/page174_5.html, a Sphaeriid
(bottom left - I don't speak Sphaeriid either)
http://www.inhs.uiuc.edu/cbd/musselmanual/page172_3.html
and an Elima (perhaps livescens).
My 2 cents
Kevin
