| Abstract Egypt has natural productive water sources dispersed alongside the Northern Delta coast like Idku Lake, the point of concern of this research. It suffers either from pollution, decline in the area or decrease in its fish production, especially in the last decades. The aim of work is to identify the changes of physical and chemical composition of lake water and sediment with facility of explanation into shape of distribution maps using inverse distance weighting (IDW) method in geographical information system (GIS) program within two seasons. Geo-referenced water and sediment samples were collected from 12 sites distributed within the two basins of the lake. Samples were analyzed for scouting the different types of pollutants and distribution of it. Results showed variability between sites and seasons. Calculated average water quality index indicated good quality in winter season (45.55) and oxygenated water system when compared with summer season (143.20). Indicators specified in organic matter (Biological and chemical oxygen demand and organic matter) showed high distribution in drainage areas. Cluster analysis indicate that locations within similar under pressure conditions of drainage waters have to large extent the same physiochemical properties. The sites in northern basin of the lake also have similar results. New projects be occur now in the lake and be observed during the collection period. The lake Idku is one of the most threatened lakes in Egypt as the area was declined and water quality became bad due to different drains and fish farms that drain into it directly. Lake Idku must followed by organized plan from different authorities as; NIOF, El-Bahiera Governorate, EEAA and Fisheries Authority for maintenance its resources. |
