----------------------------Original message---------------------------- In response to the Mississippi Delta (floodplain?) question, try the USGS topopgraphic series. By the way, if it is the floodplain you are inquiring about, you missed the states of Minnesota, Wisconsin, and Iowa. Actually the mighty Mississippi River is IN the states of Minnesota, Wisconsin, Illinois, Missouri and Iowa. The floodwaters in many places are well above the floodplains. Lets hope the weather cooperates soon and stops all the rain. Kathy A. Parsons Iowa State University
