Thermal conditions of a system may reveal a lot about the stream's attributes and potential. Water temperature in Buck Creek, Delaware County, Indiana was monitored throughout the months of June, July and August 2004. Mean monthly temperatures did not vary among sites (June F=12.79, P < 0.001; July F=54.03, p < 0.001; August F=33.84, P < 0.001; September F=16.34, P < 0.001) and all sites were significantly different from each other during the period of the study (F=98.5, P<0.001). The fish species composition and temperature data are similar throughout Buck Creek, therefore indicating that Buck Creek is an ideal location for stocking species of trout for sport angling purposes.
