The term "Atlin District" was also used synonymously with the official administrative area named the Atlin Mining District, established during the gold-mining heyday contemporaneous with the Klondike Gold Rush.  The region also includes adjoining Teslin and Tagish Lakes and the Bennett Lake area in the narrow strip of BC separating the Alaska Panhandle from the Yukon Territory.  The Atlin District is currently part of the Stikine District in the regional district system (although it is not a regional district).  The communities of the Atlin lakes district, as the area is casually called, are referred to in national weather reports as "the Southern Lakes", as in "Whitehorse and the Southern Lakes", although this also includes towns on the Yukon end of the lakes.

Camptowns usually take the same name as the district in which they are located.  For example, as mentioned the camptown for Maseru is Maseru but also the camptown for Thaba-Tseka District is Thaba-Tseka.  The exceptions to this rule are Berea District whose capital is called Teyateyaneng, Quthing District whose capital is called Moyeni and Leribe District whose capital is most often called Hlotse.

The Xiaojiang River runs 141 kilometres and its drainage area is 3049 square kilometres.  Due to loose rock structure, sparse vegetation on the banks, and the well-developed dissected troughs, large-scale debris flows frequently happen here.

Huangshan City: Huangshan (), is a prefecture-level city in southern Anhui province, People's Republic of China.

Dhaka, the capital of Bangladesh, rests on the eastern banks of the Buriganga River which flows from the Turag to the south of the district.  While Dhaka (city corporation) occupies only about a fifth of the area of Dhaka district, it is the economic, political and cultural centre of the district and the country as a whole.  Dhaka District is an administrative entity, and like many other cities, it does not cover the modern conurbation which is Greater Dhaka, which has spilled into neighbouring districts, nor does the conurbation cover the whole district, as there are rural areas within the district.

Chol Kiri District: Chol Kiri District (Khmer: ស្រុកជលគីរី ) is a district ("srok") in the east of Kampong Chhnang Province, in central Cambodia.  The district capital is Chol Kiri town located around 8 kilometres south of the provincial capital of Kampong Chhnang by road.  Chol Kiri District is the easternmost district of Kampong Chhnang.  The district shares a border with Kampong Thom and Kampong Cham provinces to the east.  Most of the district is lowing lying floodplain and the Tonlé Sap river runs through the district roughly from north to south.  This proximity to the river and the lack of high land make Chol Kiri one of the most flood prone districts in the country.  The Kampong Chhnang Department of Development has estimated that both Chol Kiri and Kampong Leaeng districts are flooded for six months of the year and that after the floodwaters have receded drinking water sources are left contaminated.
