Diel movements of brown trout were investigated using radio telemetry in the Chattooga River watershed. 24 wild brown trout were captured using electrofishing and hook and line. 18 trout were located in the main branch of the river and 6 trout were located in the East Fork creek. Radio transmitters were surgically implanted in the abdominal cavity and the trout were released at the point of capture. Trout were located once every hour for a continuous 24-hour period to constitute one diel track. Temperature and macrohabitat were recorded for each identified location of the trout. Diel tracks were collected during the winter (10 tracks), spring (14 tracks), summer (11 tracks), and fall (12 tracks). Total distance moved and diel range were obtained for each diel track. Differences in movement between river trout and creek trout were also examined. ANOVA was used to determine the effects of location, season, time of day, and macrohabitat on diel movement.
