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.

[1] [2] [3] An A$8.1 million upgrade of facilities was completed during 2012 and involved construction of a new, 2 metres (6 ft 7 in) high, concrete parapet wall on the embankment. [ 5 ] At the time of its initial construction in 1987, Split Rock Dam incorporated the latest dam technology with an intake tower that can select water from any ...

The dam's upstream face is a concrete face of 47,000 m 2 (506,000 sq ft) area, with thickness of concrete face varying from 50 cm (1.6 ft) at the bottom to 30 cm (1.0 ft) at the top. The spillway of the dam is designed for an inflow flood discharge of 450 × 10 ^ 6 m 3 (0 × 10 ^ 9 cu ft).
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]
New Exchequer Dam is a concrete–faced, rock-fill dam on the Merced River in central California in the United States. It forms Lake McClure, which impounds the river for irrigation and hydroelectric power production and has a capacity of more than 1,000,000 acre-feet (1.2 km 3). The Merced Irrigation District (MID) operates the dam and was ...
The masonry arch dam wall was designed by Lieutenant Percy Simpson who was influenced by the advances in dam engineering techniques made by the Royal Engineers in India. The dam cost £17,000 and was completed in 1856 as the first engineered dam built in Australia, and the second arch dam in the world built to mathematical specifications. [31]
