Mar Chiquita lake lies in the northeast of the Córdoba province, Argentina Republic, between 30° 20' and 3.1° OO' South latitude and 62° 10', 63° 10 ' West longitude, at 65 m above sea level. It belongs to the "Llanura Chaco Pampeana" geologic province. The study of the Mar Chiquita Lake is of great importance since this is the major body of surface water in our country. From the scientific point of view it is also important to study the lake hydrological balance, its groundwater input and output as well as the evaporation rate and the mean residence time. These latter considerations are the object of the present isotopic research
