Environmental Impact Assessment (EIA) for lesser- known creek in Benghazi was taken for initial monitoring to add data base system by taking environmental factors and water variables into consideration in order to evaluate, protect and sustainable use of lesser known creek within the city. Temperature had played a dominant role in assessing the importance of physical factors in setting the vertical limits of zonation pattern in coastal communities. However, the daily warming of creek waters, in addition to that the pollutants present in the creek, with the help of solar radiation, produce warm mixed layer of water during the course of the day. This development of this mixed layer largely depend on wind and surface currents in turn will play a key role for the productivity and also the growth of both phytoplankton and zooplankton in certain areas in the creek. Whereas, continuous addition of pollutants all along the creek especially near fish market lead to decline of water quality and increase of organic matter. Temperature, dissolved oxygen, salinity and pH will determine water quality and the redistribution of flora and fauna in the creek.
