Bloemhof Dam is a dam in South Africa. It was originally known as the Oppermansdrif Dam when under construction during the late 1960s. It is located at the confluence of the Vaal River and the Vet River, on the border between the provinces North West and Free State. The dam wall has a total length of 4,270 metres (14,010 ft) The reservoir is very shallow, and therefore needs a large area to mean anything for water storage. The area around the reservoir (dam), has been a protected area, but because it lies on the border between provinces, these became two separate nature reserves. On the North West Province side lies the Bloemhof Dam Nature Reserve, on the Free State side is the Sandveld Nature Reserve.
