The Orange River is a river in Southern Africa. It is the longest river within the borders of South Africa and the Orange River Basin extends extensively from Lesotho into South Africa and Namibia to the north. It rises in the Drakensberg mountains in Lesotho, flowing westwards through South Africa to the Atlantic Ocean. The river forms part of the international borders between South Africa and Lesotho and between South Africa and Namibia, as well as several provincial borders within South Africa.

The river was named the Orange River in honour of the Dutch ruling family, the House of Orange, by the Dutch explorer Robert Jacob Gordon. Other names include simply the word for river, in Khoekhoegowab orthography written as !Garib, which is rendered in Afrikaans as Gariep River with the intrusion of a velar fricative in place of the alveolar click, Groote River or Senqu River, derived from ǂNū "Black".

The fishing industry in the land-locked country of Laos is a major source of sustenance and food security to its people dwelling near rivers, reservoirs and ponds. Apart from wild capture fisheries, which is a major component of fish production, aquaculture and stocking are significant developments in the country. Historically, fishing activity was recorded in writings on the gate and walls of the Wat Xieng Thong in Luang Prabang dated 1560. For many Laotians, freshwater fish are the principal source of protein. The percentage of people involved in regular fishing activity is very small, only near major rivers or reservoirs, as for most of the fishers it is a part-time activity.

Edward Medard Park and Preserve, originally known as Pleasant Grove Reservoir Park, is located south of Plant City, Florida, on Turkey Creek Road in Hillsborough County, Florida. The 1,284-acre (5.20 km2) park just north of Durant, Florida was the site of phosphate mining in the 1960s by the American Cyanamid Company, before the land was donated. A dike and 770-acre (3.1 km2) reservoir were created in 1970 to provide flood protection along the Alafia River. The lake has a very extensive and irregular shoreline, and great variation is found in the lake bottom as well. The park is maintained by the Hillsborough County Parks and Recreation Department, and has camping, picknicking, and other facilities.

Wonderfonteinspruit is a small river situated in the Highveld region on South Africa. Its source has been disputed in the past although it is now accepted that the river originates in the West Rand of Gauteng in between Krugersdorp and Randfontein, at Tudor Dam, which was initially used as a storage dam for Luiperdsvlei Gold Plant. In the past the river received a majority of its water from karst springs along its course, the river flows through one of the richest gold producing areas in the world, which lead to the dolomitic compartments which fed the river being dewatered to make way for mining activities, this led to the drying up of the karst springs that fed the river.
