Densities and Habitat Electivity in Sun, Annie, Sand and Bear Creeks

Bear Creek had the highest fish density of all streams surveyed (Table 3), whereas the density of fish in Sand Creek was more than twice that of either Annie Creek or Sun Creek. Brook trout in Sun Creek, Annie Creek, Sand Creek, and Bear Creek generally exhibited a high preference for pool habitat (Table 4). Compared to age 2+ fish, however, age-1 brook trout showed a greater utilization of glide and riffle habitat.
