The Shashe River (or Shashi River) is a major left-bank tributary of the Limpopo River in Zimbabwe. It rises northwest of Francistown, Botswana and flows into the Limpopo River where Botswana, Zimbabwe and South Africa meet.Shashe Sub-basin
The confluence is at the site of the Greater Mapungubwe Transfrontier Conservation Area.
The Shashe River is dammed near Francistown at Shashe Dam. The original purpose was to supply water to the industrial city of Selebi-Phikwe.
In 1982 it was found that groundwater from the local wells in Francistown had high levels of nitrate, and was also inadequate to meet public demand,
so the public water supply for that city was changed over to using water from the Shashe Dam.
The dam also supplies water to surrounding villages, Phoenix Mine (Tati Nickel Mining Company/Norilsk Nickel) and Mupane Gold Mine (IAMGOLD).
Further downstream, the Dikgatlhong Dam impounds the Shashe near the village of Robelela, completed in December 2011.
When full it will hold .
The next largest dam in Botswana, the Gaborone Dam, has capacity of .
A pipeline from the Dikgatlhong Dam will connect to the North-South Carrier (NSC) pipeline at the BPT1 break pressure tank at Moralane.
The NSC will take the water south to Gaborone.
The confluence is at the site of the Greater Mapungubwe Transfrontier Conservation Area.
Hydrology
The Shashe River is a highly ephemeral river, with flow generally restricted to a few days of the year. The river contributes 12.2% of the mean annual surface runoff, runoff of the Limpopo Basin. Major tributaries of the Shashe River include the Simukwe River, Simukwe, Shashani River, Shashani, Thuli River, Thuli, Tati River, Tati and Ramokgwebana River, Ramokgwebana rivers. The lower Shashe is a sand filled channel, with extensive alluvial aquifers in the river channel and below the alluvial plains. These supply water for a number of irrigation schemes including Sibasa Irrigation Scheme, Sibasa and Shashi Irrigation Scheme, Shashi. Zambezi river#Geological changes to the course of the Zambezi, More than two million years ago, the Upper Zambezi River used to flow south through what is now the Makgadikgadi Pan (presently a vast seasonal wetland) to the Shashe River and thence the Limpopo River.Settlements
There is a road bridge and a rail bridge south of Francistown. The lower Shashe River forms the border between Botswana and Zimbabwe and is unbridged. However, at Tuli, Zimbabwe, Tuli, both sides of the river are in Zimbabwe and there are two legal crossing points. The Shashi runs through the Shashi Irrigation Scheme and the Tuli Block.Dams
