13.4.5 Water Quality of the Coastal Lakes
The aquatic ecosystem of the coastal lakes is a major concern since good ecosystem
health is essential not only for sustaining lake services to local populations but also
for maintaining biodiversity (Zakaria et al. 2007). Egyptian Environmental Affairs
Agency (EEAA) initiate monitoring program to check the water quality of the
coastal lakes. The results of the monitoring of water quality of the lakes under investigation during August 2009 carried out by Central Department for Water Qualitythe national program for monitoring the Egyptian Lakes-EEAA are listed in
Table 13.2 as reported in EEAA report of Egypt state of Environment of year 2012
(EEAA 2015). Table 13.3 listed the maximum and minimum values of annual average of the chemical parameters of water and sediments of Edku Lake according to
Masoud et al. (2005).
13.5 Environmental Indicators
13.5.1 Monitoring Dissolved Oxygen
Dissolved oxygen (DO) levels in lake water are influenced by many factors, including water temperature, the concentration of algae and other plants in the water, and
the amount of nutrients and organic matter that flow into the water body from the
watershed. Oxygen is produced through plant metabolism (photosynthesis), and it
