Abstract:ABSTRACT Navigation locks on the Upper Mississippi River currently receive heavy use from both commercial barge traffic and recreational craft. Multiple regression analysis of lockage statistics suggests a critical level may exist, below which barge traffic volume has little impact on recreational lock use, but above which it physically constrains recreational lockage. The capacity of the Upper Mississippi River for lock chambers at Alton, Illinois. This may adversely impact recreational use of locks by raising commercial traffic levels above the critical level at several other locks on the river.
