Abstract
Abstract: Some ecological factors of the artificial lakes in AL-Jadria were studied .A fish lake in AL-A, ras Tourist Island was selected to carry out of this study. water samples were collected During summer 2008 till spring 2009 .some seasonal changes of nutrients were measured (SO4 and Sio3). Other relational indicators were studied like TDS, BOD5 and chlorophyll-A .The results of this study showed that there were clear seasonal changes in temperature of air and water. the range of air temperature was recorded between (3-51°c),whereas the water temperature range from (4-37°c).the pH lake water was recorded between (7.6-9.1) which is alkaline, the electrical conductivity reached the highest value at(3800µs/cm ) in march 2009. whereas the lowest value recorded at (300µs/cm) in December 2009. It was also observed that the average of TDS were significant in Summer and Autumn .The BOD5 and nutrients were shown clear changes in accordance (and Sio3 ,SO4, PO4, NO3) changes of the seasons and the locations of the stations .
