[4]: 152 The dam, located in the Canyon of the Nechako River, is a rock-filled, clay-core dam measuring 97 metres high and 457 metres wide (at the top). [4]: 152 Construction involved over 3 million cubic metres of material. [8] Concrete was injected in bedrock fissures below the dam to stabilize the foundation. [9]
The dams also supply water for the town of Walgett and generates hydro-power for the national grid. [1] The dam wall constructed with 1,048 cubic metres (37,000 cu ft) of concrete faced rockfill is 66 metres (217 ft) high and 484 metres (1,588 ft) long.
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.
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 ...
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 ...
