Abstract
Lake Edku is one of the northern coastal lakes in Egypt, located at the western part of the Delta Nile. It receives its water from two drains namely: Elkhairy and Berzik drains. The lake is connected to the Mediterranean Sea through a narrow channel, Boughaz El-Meadia, which is opened into Abu Qir Bay, then to the sea. Seven stations were studied to represent three habitats as 1)drainage habitat; 2) lake-sea connection, which is considered the intermediate zone between Lake Edku and the Mediterranean Sea; and 3) the body of Lakehabitat. Physical and chemical parameters such as temperature, turbidity,alkalinity, water pH, salinity, electrical conductivity, water depth, dissolved oxygen (DO), chemical oxygen demand (COD), biological oxygen demand(BOD), water hardness and primary productivity were determined during the period from January to December 2004. It was found that many of these ecological factors were impacted seasonally.
