This research aims to evaluate the water quality of the Al-Sain lake which feeds mainly the Lattakia city and a part of the Tartous city of drinking water purpose. In this paper, we study a group of physical and chemical factors for the water of the Al-Sain lake during the years of available data (1991-2004-2007-2011), samples were taken from four different locations according to the program approved by the concerned staff to monitor and protect the lake, namely: (Lattakia water supply point, Tartous water supply point, irrigation point, southern spring observatory), and we calculated the quality index for drinking purposes using US approved methodology of National Sanitation Foundation. Nine factors have been adopted: (dissolved oxygen, fecal coliforms, pH, BOD5, temperature, phosphate, nitrates, turbidity, and total solids). The research result showed that the classification of water quality was good in all four monitoring points during the years 1991 and 2004, noting a significant improvement of the quality in 2004, and decreases slightly during the years 2007 and 2011 for monitoring points in the Lattakia water supply and irrigation points, but water quality still keep maintain a good classification, while the quality of the water goes down within the threshold of middle classification for the Tartous and southern spring observatory monitoring point.

The research aims to determine the water Quality Index for the Lake of 16 Tishreen Dam. To achieve this aim, we have carried out different periodical physic-chemical and bacterial measurements on the lake water. The samples were taken at five sites along the lake for a period of one complete year. The indicators that have been measured are: Temperature, Turbidity, PH, EC, DO, BOD5, NO3, NO2, NH4 ,PO4, F.C. Measurement results were represented diagrammatically, and compared with the Syrian Specification Standards for portable Water. The lake was classed according to these Indices: Malays quality index, Canadian Indices (NSFWQI), (NEWWQI). The Lake was Classed according to these indices as following: from third grade at all locations (Malays Index), from second grade at the middle lake and from a third grade to all other locations (NSFWQI), and from second grade at all locations (NEWWQI). According to this indices the water is not good for drinking and needs treatment. The Productivity of the lake was determined. The Lake is Eutrophic according to TN,TP in the middle but Hypertrophic according to TN,TP in all other locations.

This research aims at studying the most important indicators of water pollution leading to nutrient increase (eutrophication) in AL- Basel Dam Lake, and connecting them with pollution sources represented by untreated sewage water and agricultural d rainage water, including rain water coming from the lands surrounding the lake. Among the most important of these indicators are total phosphorus (TP) and total Nitrogen (TN). Samples were taken and analyzed from four sitesof the lake (S1, S2, S3, S4) were conducted periodically. The work continued to conduct tests for full hydrological cycle as of January (2016) until December (2016). The study showed that the lake was highly fertilized according to the (TN- TP) this indicates that the lake is affected by the pollutants it encounters, especially the wastewater pollutants. The specific component of algal growth was determined by knowing the ratio between total nitrogen and total phosphorus. The TN / TP ratio was greater than 10, so total phosphorus is the specific component of algal growth in the Basel DamLake.
This study includes the possibility of using Artificial neural networks (ANNs) with back-propagation algorithm in a short-term prediction of water level in Qattinah Lake. The data used are the water level data in the lake and rainfall data for the period from 1/5/2007 to 28/2/2005. 2009).
