This study was conducted between November 2022 and August 2023 to investigate the physical and chemical properties of Keşiş lake and Sıhke and Gövelek pond waters in Van province. In the measurements, the average dissolved oxygen was 8.30 ± 1.60 mg/L, water temperature was 12.68 ± 2.22 °C, turbidity was 12.25 ± 6.01 NTU, electrical conductivity was 476.56 ± 62.55 μS/cm, salinity was 0.23 ± 0.03 mg/L, pH was 8.92 ± 0.31. TDS 233.32±28.31 mg/L, Cl2 42.25±28.21 mg/L, Ca+2 46.78±15.17 mg/L, Mg+2 24.87±8.55 mg/L, Ca+Mg 138.74±3.96 mg/L, CO32- 11.11±8.96 mg/L L, HCO3- 133.39±27.10 mg/L, NO2- 0.01±0.01 mg/L, NO2-N 0.01±0.01 mg/L, NO3- 2.51±1.79 mg/L, NO3—N 0.63 ±0.52 mg/L, NH3 0.32±0.27 mg/L, NH3-N 0.27±0.23 mg/L, NH4 0.35±0.29 mg/L, PO4-3 0.29±0.25mg/L, P 0.07±0.05 mg/L, SO4 112.27±11.76 mg/L, K 4.16±0.85 mg/L, Na 33.49±14.46 mg/L, B 0.86±1.17 mg/L, total hardness 21.68±0.62 mg/L, organic matter 3.38±2.02 mg/L, SAR 0.97±0.46 mg/L, Fe+2 0.066±0.082 mg/L, Mn+2 0.007±0.002 mg/L, Cu 0.003±0.001 mg/L, Ni DLA and Zn 0.003±0.002 mg/L, Cr+6, Ni and Co DLA. has been made. When evaluated according to water quality classes, parameters other than pH were determined to be of quality that can be used in agricultural irrigation, and parameters other than ammonia value were determined to be suitable for fishing.
