The objective of this work was to study the chemical, physical and microbiological properties of Dumat Lake in Al-Jouf region, Saudi Arabia. Limnological parameters were evaluated in February 2009 from different lake sites and from northern reservoir (Main source of water to the lake). The temperature and pH values of the lake sites and northern reservoir were measured and ranged between 20.9-22.1°C and 18.8°C and 8.25-8.7 and 7.25, respectively. With respect to temperature and pH-values, all nitrogen forms were all below the standard. The measured hardness values (8390-2105 mg as CaCO L ) indicated that the lake sites water was 3 1 described as very hard but (166 mg as CaCO L ) indicated that the northern reservoir was very soft. The 3 1 surface water quality of Dumat Lake could be classified as class 1. The data obtained from lake sites and northern reservoir could be used as a baseline and reference points when assessing further changes caused by nature or man in the lake.
