This study was designed to assess whether fish community data collected for the Long Term Resource Monitoring Program LTRMP from six regional trend analysis RTA areas of the Upper Mississippi River System UMRS can he used to make inferences to the system as a whole. Spatial coverage of fish monitormonitoring for three LTRMP field stations was extended to outpools immediately above and below RTA pools 4 and 13 and the Open River Reach from June 15 to October 31. 2000 Also. we sampled Navigation Pools 19 and 20 using LTRMP electrofishing methodology in September 2000. Multivariateate statistical analyses were used to group pools on the basis of fish community composition and community structure. Cluster analysis of community composition and structure data revealed two major groups of pools. upper pools i.e., northern and lower pools i.e., southern.
