Welbedacht Dam dam wall. For various reasons, however, constructing a smaller scheme on the Caledon River was implemented before completion of the Vanderkloof Dam. The Welbedacht Dam on the Caledon River was constructed as the main storage element of the CMRGWS and water is abstracted from this dam for transfer to Bloemfontein and various smaller users along the way. The Welbedacht Dam is a concrete barrage-type dam on the Caledon River, which was designed and constructed by the Department of Water Affairs. The dam has a catchment area of some 15 245 km² with a natural mean annual runoff (MAR) around 1210
