The interaction between surface water represented by Tigers River, Fish Lake, drainage and groundwater was examined in this study. Samples were collected from Al-Azezeyia city for stable isotope (2H and 18O). Samplings of water were taken during January-September 2016 during the period of breeding fish. Two samples were taken from a fish lake, three samples from Tigers River and one sample from water drainage. The aim of this research is to assess the interaction of a fish lake on surface water by using isotopic techniques. The values of stable isotopes of 18O range -7.78 -8.10 ‰, -7.43-8.11 ‰, -3.2- 3.3 ‰ and -6.0-6.2 ‰. The values of Deuterium range -45-45.56 ‰, -46.7- -45.72 ‰, -37.87-37.98 ‰ and -28.4-29.7 ‰ in the fish lake, Tigris river, groundwater and water drainage, respectively. The results show there is no effect of interaction between the fish lake and Tigers River due to a short distance between the river and the lakes, lack evaporation effects and high flow rate.
