The Southeastern United States is rich in freshwater fish diversity. However, habitat alteration has a profound impact on fish assemblages across this region. The Red River, Louisiana has historically been diverse in fishes. In the 1980's and 1990's a series of five lock and dams were constructed to facilitate watercraft traffic. To assess assemblage changes attributable to lock and dam construction, I analyzed historical survey data from the Red River (1966-2002). I compared changes in assemblages pre-and post-construction of the first lock and dams. The results show similar species richness across time, but the data also show a shift in fish assemblages after dam construction. Functional diversity analyses are similar, with the time period post-construction showing a rapid decline in Periodic species, and a increase in Equilibrium species. These results indicate a multi-metric approach may be more informative that traditional species richness values when examining assemblage change.{A0}
