The reservoir was initially built to provide water to petrol plants like ESKOM'S Tutuka Power Station, Duyha Power Station, and the Malta Power Station. Grootdraai was constructed in 1981, and more comfortable, stylish, and affordable hotels are being established around the area to accommodate tourists. It is 42 m high with a 350 million m3 volume. The 2180 m long reservoir lies along the Vaal River. The dam experiences stronger winds than on the Vaal Dam hence it is a perfect windsurfing area.
