The results showed a poor inhabitant of aquatic birds i.e. yellow wagtail （Motacillaflava）; Black-winged Stilt （Himantopus himantopus）; shelduck （Tadorna tadorna）; Squacco heron （Ardeola ralloides）; Moorhen （Gallinula chloropus）; the bolti （Tilapia nilti）. Equally, only four plant species were predominant in the lake area i.e. synonym （Tamarix aucheriana）, a large perennial grass Phragmites australis, Athel pine or tamrisk （Tamarix aphylla） and synonym Zygophyllum simplex. Twelve fishes failed to survive longer than 45 minutes while another 6 fishes survived only in tributary water. Student T-Test biostatics analysis regarding the concentrations of the Total Dissolved Salts （TDS） in designated three parts of the lake showed significantly higher （P〈0.01〈0.0001） than acceptable limits for human usage, aquatic and natural habitat and perhaps for agricultural purposes. Similarly, the pHs of the waters were significantly alkaline （pH 8.9） and Eutrification of the lake waters clearly stand inappropriate for irrigation unless treated. The domestic pollutants were scattered almost all over the beaches as well as within the lake itself denoting unsafe of the lake as neither for natural habitats nor for tourism unless further attention is given by the municipal of Al-Jouf展开更多
