In this study, three drinking water treatment plant supply springs were selected within different sites in Sulaymaniyah province- Kurdistan region of Iraq. Samples collected over period eight months from May to the end December 2015.
 Five stations selected, Stations 1, 2 and 3 located at Bestan Sowr project Sharazur district, station 4 was Saray Subhan Agha Said sadiq district 5 Khurmal Halabja district.
 The study involved a qualitative (identification) quantitative (Density Total count) phytoplankton for stations.
 A total 155 algal species identified belong 9 classes all studied stations, 80 belonged Bacillariophyceae (diatoms), 35 chlorophyceae, 30 Cyanophyceae, Euglenophyceae, each Crptophyceae Pyrophyceae 1 Chrysophyceae, Dinophyceae Xanthophyceae. Diatoms dominated (according count taxa) other sites, Chlorophyceae formed second most group Cyanophyceae third sites.
 results studying recorded highest density during Station1 (18377.28 ind×103/l), followed by (12513.34 ind×103/l) Station (4779.45 3. Count ranged between 5913×103 cell/l 29×103 cell/l.
