The present investigation has been made to investigate the limnological aspects of Ghunghutta reservoir from June 2016 to May 2017 in Surguja district Chhattisgarh. The reservoir constructed for the irrigation and its also utilized for pisciculture. The physico-chemical parameters of reservoir varied seasonally such as Turbidity (16.46 to 35 cm) pH (7.2 to 8.8) TDS (119 to 236 mg/l) Dissolved oxygen (6.6 to 9.8mg/l) Total alkalinity (251 to 368 mg/l) Total hardness (71 to 128 mg/l) Chlorides (30 to 69 mg/l) A total of 13 sp. of phytoplankton and 12 sp. of zooplanktons were identified. The Chlorophyceae and Rotifers recorded dominance phytoplankton and zooplanktons respectively. The physicochemical characterstics and planktonic diversity showed the reservoir water is suitable for irrigation as well as pisciculture.
