The Shirin Tagab River is a river in Afghanistan, which travels {{convert|320|km}} before ending in an inland delta around Andkhoi.{{cite web|url=http://www.norplan.af/DocumentsHGS/Hydrogeology/HydrogeoAtlas/Atlas%20FINAL%20version%201%20slim/Atlas%20Complete%20vF1.pdf|accessdate=24 July 2020|title=A Hydrogeological Atlas of Faryab Province, Northern Afghanistan|date=2014|website=norplan.af|archive-url=https://web.archive.org/web/20180903184042/http://www.norplan.af/DocumentsHGS/Hydrogeology/HydrogeoAtlas/Atlas%20FINAL%20version%201%20slim/Atlas%20Complete%20vF1.pdf|archive-date=2018-09-03}} The river's watershed has 504 settlements with a population of 605,972, and covers the majority of Faryab Province.{{cite web|url=http://aizon.org/Watershed%20Atlas%20of%20Afghansitan/Volume%20I/Watershed%20Atlas_Part%20IV.pdf|title=Description of Watersheds Part IV|website=aizon.org|accessdate=26 July 2020}} Downstream, the river is brackish/saltwater. In addition, the river is a source of water-borne diseases.

Course

The river begins flowing west in the eastern part of Bilchiragh District, and is joined by the river Chashma-i Khwab near the district center, after the Chashma has flowed through scenic rapids. The Tagab then turns north, flowing through the northeast corner of Pashtun Kot District and western Khwaja Sabz Posh District. As it enters Shirin Tagab District, the river is joined by the Astana river. At Araba, an irrigation canal takes the majority of the river's water. Then, near Pata Baba in Dawlat Abad District, it is joined by the Shor Darya River, which carries the water from the Almar, Qaysar, and Maimana rivers. The Shirin Tagab then dissipates around the city of Andkhoy, on the edge of the Dasht-i Shortepa.{{cite web|url=https://www.researchgate.net/publication/282807588|title=Integrated Groundwater Study in Jalaier Valley, Shirin Tagab District of Faryab Province, Afghanistan|author=Mohamad hassan Saffi|date=June 2010|accessdate=25 July 2020|website=researchgate.net}}

The river used to run to the Amu Darya before the development of irrigation and the diversion of water.

Economy

Most of the river's water is used for irrigation. Sometimes, the large amount of water being diverted leaves the natural waterway nearly dry; little water reaches Andkhoy in the summer months.

About {{convert|1,000|km2}} of its watershed is cultivated, and another 6,000 serving as rangeland.
