Abstract
In the summer of 2001, benthos were collected from 20 stations in the Grand River system (Wright, 2001). This report has 3 principal objectives: 1) Calculate several indices of community composition and use those data to infer the present condition of the aquatic environment; 2) Determine if there have been significant changes in community composition from 2000 to 2001 and whether those changes correlate with changes in water quality; and, 3) Determine if spatial trends in 2001 correlated with indicators of human development (i.e., landuse and/or water chemistry).
