The composition and structure of the La Grange Reach turtle community is largely 
unknown. Since 1990, the Long Term Resource Monitoring Program (LTRMP) has been 
monitoring fish on the La Grange Reach of the Illinois River. In conjunction with the 
LTRMP fish monitoring staff have been collecting turtle data from accidental catches in 
the fish gear since 1992. A total of 1899 turtles have been caught using LTRMP fish 
gears. With this data we will examine species composition, size structure, habitat 
preference and gear sex ratios.
