AbstractThe Nile River has always been Egypt's life blood for millenniums since it is the major source of freshwater to the country. The High Aswan Dam was constructed in 1972 to work as a long term storage system to feed the country with its vital water resources according to its needs. The construction of the dam created a huge reservoir Lake Nasser which extends over a large surface area of 6000 km2. It is considered one of the largest man made lake in the world. Since then, the lake has been the strategic water bank of Egypt that needs to be conserved and protected to maintain its integrity. Over the years, the river and its lake have maintained a high quality but due to the recent developmental projects associated with the economic growth of the country, water quality becomes an issue of great concern to any freshwater body. Considering the precious value of its water resources, Egypt has launched a monitoring program to check the water quality of its freshwater sources. The network established by the Ministry of Water Resources and Irrigation covers Lake Nasser, the Nile River and its tributaries along with all canals and drains, and that extends to the groundwater aquifer as well. The target was to keep record of the water quality parameters of these resources over the years to maintain its sustainability and ensure its integrity. This study focuses on analyzing the major water quality parameters that determine the health of water at Lake Nasser. A comparison between the water quality status in 1991 and 2001 has been made to observe the changes taking place due to the environmental variations happening over the years.
