Pradhan and Vikky Kumar S. G. College of Agriculture amp Research Station IGKV Jagdalpur . India Corresponding author ABSTRACT Dalpatsagar reservoir is one of the oldest water bodies in Jagdalpur city at Bastar region of Chhattisgarh state. The water bodies is severely infested with different kind of aquatic weed species throughout the year since last decade and it modified the structure of habitat and influenced the aquatic organism. The physico-chemical properties of Dalpatsagar reservoir was changed with season year after year that influence the quality of water and pond ecosystem. The study was carried out at Dalpatsagar reservoir during June 2019 to Keywords May 2020 throughout the year. To assess the physico- chemical properties of pond water sample was collected from 11 different locations at Dalpatsagar reservoir. The physico- Physico-chemical chemical properties of Dalpatsagar reservoir was observed significantly varied with Properties Weed dynamics different season the maximum value of pH and EC dSm-1 was recorded in summer season at site of Jhada Tarae JT while the minimum value of pH at the site Article Info of Mundra Dhipka MD and EC at Housing Board Drainage HBD was recorded during monsoon season. The value of TDS was highly varied with different Accepted season the TDS was maximum mg L at Jhada Tarae JT in summer season while 17 October 2020 it is observed minimum at Jhada Tarae JT during monsoon season. The amount of Available Online CO3 and HCO3 mg L and mg L respectively was observed higher during 10 November 2020 winter season
