"Quri Gol" marshland is located km 30 Tabriz city, over the transit road of Tabriz - Tehran, and km 18 of Bostanabad. Located in the Bostanabad, the area of the drainage basin of this marshland is 3,146 hectares, itself is a piece of the catchment area of the Aji Chay river which is debouching into the Urmia Lake. The nearest villages to this marshland are Yousefabad and Omnab. The area for this marshland is stated between 160 to 200 hectares. This area has a dry cold climate.
There is no permanent river existing in the catchment area of "Quri Gol" and a large number of waterways are like watercourse and ended backwater. In addition, a large number of waterways (especially, a grid of canals at the western area) are lost before reaching the lake. This verifies our theory that we only have groundwater flows and interflows.
