Water samples were taken from Rawal Lake and its catchment area during January and August to study seasonal impact on prevalence of antibiotic resistant bacteria namely Escherichia coli (E. coli), Salmonella typhi (S. typhi) and Klebsiellap neumonia (Klebsiella) in the aquatic environment. The Rawal Lake and its whole catchment area were contaminated with the pathogenic bacteria except the two tributaries away from human population and activities. Results of the investigation revealed that isolates of E. coli, S. typhi and Klebsiella collected during August and January were 45 to 100% and 40 to 90% found antibiotic resistant respectively. This difference may be due season depended human activities and favorable temperature. Selected isolates of the three bacteria were examined for Erythromycin (Ert), Kanamycin (Kan), Ciprofloxacin (Cip), Norfloxacin (Nor), Ofloxacin (Oxl), Ampicillin (Amp), Vancomycin (Van), Amoxicillin (Amx). No isolate was resistant to less than four antibiotics understudy, highest resistance was shown by isolate of E. coli named as EC6 which was resistant to all the eight antibiotics. Untreated wastewater from recreational sites, hotels and hospital entering into the catchment area was mainly observed responsible for the resistant bacteria.
