Abstract: This study was conducted on lake Ehuikro, located in Bongouanou (Côte d’Ivoire) from April 2017 to March 2018. Each month, the physico-chemical parameters of the water were measured at three (3) identified stations. In order to analyse its ecological status, the following equipment was used: Conductivity meter Model Sx713; Model Sx711 pH meter; Model Sx716 oximeter and Secchi disk, which made it possible to determine the annual average values: The dissolved solids rate was 154.13 ± 1.22 mg/L (long dry season) and 181.67 ± 3.78 mg/L (short dry season). Conductivity 250 ± 3.07 Ms/cm (short rainy season) and 297.75 ± 2.66 MS/cm (long dry season). Hydrogen potential 7.35 ± 0.13 (long dry season) and 8.09 ± 0.55 (short rainy season). Temperature 27.06 ± 0.67 °C (main rainy season) and 28.45 ± 0.05 °C (main dry season). Oxygen saturation level 42.67 ± 3.77% (minor dry season) and 67.93 ± 6.96% (long dry season). The dissolved oxygen level was 3.07 ± 0.64 mg/l (short dry season) and 5.24 ± 0.45 mg/l (long dry season). The phosphorus concentration was 0.03 ± 0.01 mg/l (short rainy season) and 0.06 ± 0.01 mg/l (long rainy season). The nitrate concentration was 0.01 ± 0.1 mg/L (long dry season) and 0.02 ± 0.1 mg/L (main rainy season). Transparency 0.44 ± 0.02 cm (main rainy season) and 0.68 ± 0.05 cm (minor dry season). Depth 2.71 ± 0.36 m (main dry season) and 4.20 ± 0.51 m (main rainy season). The results obtained reveal that certain physico-chemical parameters show signs of disturbance probably linked to local anthropogenic activities.
