In this paper, the final output of the satellite altimetry on the surface of Lake Urmia is investigated. From 1995 onwards, the level of Lake Urmia has been declining. From 2015 to 2019, it has had a steady trend and there are not many changes, the main reason being the policies of reviving Lake Urmia. After 2019, there is an increase of about 1.5 meters, which is due to good rainfall this year, and after that, a decreasing trend is observed. In the middle of 2020, with the increase of precipitation, the level of the lake increases by about 20 cm and then reaches the level of 1271.5 meters again. However, after 2015, with the policies of Lake Urmia restoration, the downward trend has been controlled and the level has remained constant. However, these policies do not seem to be sufficient and there is a need to reconsider the water resources management in the region.

Water is a major source of economic development, social security and poverty reduction. The value of this resource on the one hand and its limitation on the other hand has led to increased management measures to maintain the quantity and quality of water by different communities. In this research, the water quality index (WQI) for the Dehroud and Tang Eram regions of Dashtestan in 2007 has been investigated. The average WQI in 2007 is 66,798. WQI was better off in the Northeast in 2007 than in the Southeast. The maximum values ​​of PH, TDS and EC in 2007 are 7.9, 5000 and 7500, respectively.
