Water from the river is substantially redirected for irrigation, and the Alamüdün District of Chüy Region is named after the river.
The river is {{convert|78|km}} long, and has a drainage basin of {{convert|317|km2}}.{{cite encyclopedia|url=https://new.bizdin.kg/media/books/География_Кыргызстана.pdf|title=Аламүдүн|trans-title=Alamüdün|encyclopedia=Кыргызстандын Географиясы [Geography of Kyrgyzstan]|page=181|language=ky|year=2004|location=Bishkek}}[http://www.welcome.kg/ru/kyrgyzstan/nature/wot/170.html Основные гидрографические характеристики рек Чуйского бассейна] or 417 km².{{rp|p.419}} The average rate of water flow is 6.33 cubic meters per second, with a maximum of 300 cubic meters per second and a minimum of 0.74 meters per second.
The source of the Alamüdün is a glacier on the northern slope of the Kyrgyz Ala-Too range. In the upper parts the flow is turbulent, and it passes through narrow mountain gorges. As it enters the Chüy Valley, the river bed widens and becomes less steep. The river flows through the city of Bishkek, where its channel has been reinforced with concrete barriers, from south to north.
Within the watershed of the river there are 22 small lakes with a total surface area of 0.8 km² and 53 glaciers with an area of 74.2 km².
Snow-melt in the summer (May through September) results in high waters, and low-water occurs in the winter. The river has 33 small tributaries, the largest of which is the Chungkurchak, at 19 km long.
Social import
There is a water draw-off at the entrance to the Alamüdün Gorge in the Chüy Valley, not far from the village of Kök-Jar.
Villages on the banks of the Alamüdün include Kök-Jar, Tash-Moynok, Besh-Künggöy, and Alamüdün.
There have been reports that the river fills with garbage.[http://reporter.akipress.org/news:53102 Река Аламедин в Бишкеке заполнена мусором] It has also been reported that waste water from certain facilities has been polluting the river, making it unsafe as a source of drinking water.[http://www.vb.kg/doc/193449_reka_alamedin_pod_ygrozoy.html Река Аламедин под угрозой]
In July 2015, the river flooded in the village of Arashan. Relief efforts were hindered by the fact that heavy equipment could not be transported through the village due to narrow streets.[https://24.kg/proisshestvija/16545_v_sele_arashan_reka_alamedin_vyishla_iz_beregov_/ В селе Арашан река Аламедин вышла из берегов]
