==Course== The river flows through the municipal territories of Chodská Lhota, Kdyně (briefly) and Domažlice in the Czech Republic, and through Eschlkam, Furth im Wald, Arnschwang, Weiding and Cham in Germany.
==Bodies of water== A significant body of water built on the Chamb is the Drachensee Reservoir, located in the territory of Furth im Wald. It was built in 2009 and has an area of {{cvt|175|ha}}.<ref>{{cite web |title=Willkommen|url=http://www.furth-drachensee.de/index.php/de/|website=furth-drachensee.de|language=de|access-date=2025-03-17}}</ref> The main purpose of the reservoir is flood protection (river flow regulation). In addition, the western part of the reservoir is used for recreational purposes and the eastern part is a nesting ground for many species of water birds.<ref>{{cite web |last=Šavlová|first=Monika|title=Nevšední zážitek kousek za hranicemi.

==Nature== A population of Eurasian beavers (protected within the Czech Republic) lives in the upper course of the river. The rising water in the Chamb due to beaver dams has spilled over the banks and caused damage to people's homes. In January 2015, the Department of the Environment allowed removal of one such dam.<ref>{{cite web |last=Bauerová|first=Helena|title=Bobří hráze vylévaly potok Koubu z koryta|url=https://domazlicky.denik.cz/zpravy_region/bobri-hraze-vylevaly-potok-koubu-z-koryta-20150110.html|work=Deník.cz|language=cs|date=2015-01-10|access-date=2025-03-17}}</ref>
