This study was conducted from July 2018 to July 2019 at a rate of two visits per month at Lake Dam 16 th Tishreen, the results showed the presence of a Cormorant Phalacrocorax aristoteli in the study areas (floating cages, reservoir).As a result of monitoring and paint caunts at the two sites selected from the lake. We recorded of 398 individuals of Phalacrocorax aristoteli from them 355 and 147 from first and second site, respectively and the recorded Phalacrocorax aristoteli the highest frequency rate around the floating cages. The numbers of recorded bird species varied according to the months of the year, from 10 individuals during July(2018) to 180 in March while it migrated in May 2019. Some ecological coefficients (Species richness factor, variation factor) was studied where it was found that its numbers were less variable and therefore more stable in the basin area with a different coefficient (0.47) and it appeared that march 2019.
