A concrete-face rock-fill dam (CFRD) is a rock-fill dam with concrete slabs on its upstream face. This design provides the concrete slab as an impervious wall to prevent leakage and also a structure without concern for uplift pressure. In addition, the CFRD design is flexible for topography, faster to construct and less costly than earth-fill dams.
The Cotter Dam is a concrete gravity and rockfill embankment dam across the Cotter River, located in the Australian Capital Territory, Australia. Both the dam and river are named after early settler in the area Garrett Cotter. The impounded Cotter Reservoir is a supply source of potable water for the city of Canberra and its environs.
The Tokwe Mukosi Dam or Tugwi Mukosi Dam [1] is a concrete-face rock-fill dam on the Tokwe River, just downstream of its confluence with the Mukosi River, about 72 kilometres (45 mi) south of Masvingo in Masvingo Province, Zimbabwe. [2]

In the 19th century, large-scale arch dams were constructed around the British Empire, marking advances in dam engineering techniques. The era of large dams began with the construction of the Aswan Low Dam in Egypt in 1902. The Hoover Dam, a massive concrete arch-gravity dam, was built between 1931 and 1936 on the Colorado River.
Split Rock Dam is a minor ungated concrete faced rock fill embankment dam with concrete chute spillway across the Manilla River upstream of Manilla in the north-western slopes region of New South Wales, Australia. The dam's purpose includes flood mitigation, irrigation, water supply and conservation. The impounded reservoir is called Split Rock ...
Nine miles upriver, machinery tore into the foundation of a second dam, Copco No. 1, carving away some of the last fragments of the sloping concrete barrier that once towered above the Klamath River.
For dam construction, two cofferdams are usually built, one upstream and one downstream of the proposed dam, after an alternative diversion tunnel or channel has been provided for the river flow to bypass the foundation area of the dam. These cofferdams are typically a conventional embankment dam of both earth- and rock-fill, but concrete or ...
