This study has provided significant information about several aspects of boating conflicts between recreational boaters and commercial tow boat operators on the Illinois River and on the Upper Mississippi River. The first insight gained is that both recreational boat operators and commercial tow boat operators are willing to be interviewed about their attitudes, preferences, and suggestions for improvement. Survey forms were used to personnel interview 207 recreational boaters, 21 commercial tow boat operators and 10 Corps of Engineers lock personnel.

Includes extraordinary and special sessions.
