I saw your notice about the Mississippi project. A couple years ago I published a very long poem called "Forth of July", in three volumes. The third vol., "July", is basically a literary/imaginary/historical trip up & down the Mississippi. A couple sections of it (connected with New Orleans) are published in the online magazine Jacket (http://jacketmagazine.com - issue # 9). The entire poem is available in 2 volumes: Stubborn Grew (http://www.spuytenduyvil.net) and The Rose (http://www.xlibris.com/HenryGould.html). "July" itself (also included in "The Rose") is available in electronic format via the XLibris site.

This is probably not exactly what you're looking for! But possibly these river poems might come in handy for some related aspect of your project. Good luck with it!
