Abstract
The aim of this study is to evaluate the seasonal variations of Mosul dam lake by measuring the temperature, dissolved oxygen (DO) and biochemical oxygen demand (BOD) during the period from July 2018 to April 2019. Twenty two sites were selected within the studied lake. The obtained results were integrated with the geographical information system (GIS) using spatial images to create maps utilizing Arc map software. These maps were used to demonstrate the concentrations of the investigated parameters during the study period. The results show that all parameters were within the accepted levels, indicating the good status of the lake.

Lakes are key inclusions of the earth's landscape
Remote sensing data used in this study was formulated as Tagged Image File Format (TIFF)
dissolved oxygen (DO) Our study found that water DO had its highest mean value (12.33 ± 0.40 mg/l) that was recorded in site 22 during spring season
Summary
Lakes are key inclusions of the earth's landscape. They are remarkably important environments that provide a range of products and administrations to mankind. Advanced GIS innovations use digital data, for which different digitized information creation methods are utilized [2]. GIS can relate to the information by utilizing area as the key variable. The length of the lake is approximately 45 km and its width ranges from 2 to 14 km with a water surface area of about 380 km at a maximum operation level of 330 m a.s.l [4]. The climate of the study area characterized by hot and dry summers and cold winters with rare snow [6]. Twenty two stations within Mosul Dam Lake were chosen tocover all the lake’s regions. The studied stations names and their coordinates are given in Table-1
