Limnological study of Lentic Fresh Water Ecosystem during Summer Season: Nakki Lake-Mount Abu, Rajasthan, India

Limnological parameter plays a key role in determining the ecological biodiversity. Planktonic diversity can be considered as a major key factor for determining the portability of water. Nakki Lake has the greatest importance amongst the localised. With a seasonal survey, the specific status of limnological characteristic and planktonic diversity in Nakki Lake have been studied through different weather cycles (2017) across three region based on the geography and in contact with human population over top and bottom water samples. With moderately alkaline water (pH 7.08), alkalinity of (102.16 mg/l) and other limnological parameters showed low mean values including TDS (161.83 mg/l), chloride (109.73 mg/l), and hardness (95.66 mg/l). The average dissolved oxygen levels were at 5.75 mg/l while average nitrate and sulphate levels were 31.19 mg/l and 123.73 mg/l respectively. Based on the results of quality parameters of water and soil, Nakki Lake is eutrophic.
