The purpose of this study is to determine the water quality of the 16 Tishreen Dam Lake and the water outlet of the lake (Ain Al Baida irrigation tunnel) to find out the possibility of diverting part of the lake water to the drinking water network in Lattakia city. Water samples were taken seasonally for analysis to determine the suitability for drinking from three sites, namely the northern inlet to the lake (Ghamam Bridge), the 16 Tishreen Dam Lake, and the Ain al-Bayda irrigation tunnel during the period 2018 and 2019. the standard plate count agar procedure was used for analyzing samples for heterotrophic bacteria (HPC). Water quality parameters (pH, Tur, NO3, NO2, NH4+, PO4-3, and TOC) for the same samples were measured. Results showed significant differences for (HPC). The highest count was (40* 10-2 CFU/ ml) in the river water, and spatial analysis showed that the (HPC) for the river samples correlate with NH4+ (r =0.71).  Then decreased in the water of the dam lake because of stratification, with a linear correlation with turbidity (r =0.87). Then increased again in the tunnel, with respect to phosphate relationship with HPC (r =0.91). Therefore, the treatment plant must be established in order to connect it to the drinking water network.
