Modern zoned-earth embankments employ filter and drain zones to collect and remove seep water and preserve the integrity of the downstream shell zone. An outdated method of zoned earth dam construction used a hydraulic fill to produce a watertight core. Rolled-earth dams may also employ a watertight facing or core in the manner of a rock-fill dam.
Meadow Grounds Dam is categorized by the Pennsylvania Department of Environmental Protection (PADEP) as a High Hazard (Category 1), size class B structure. The drainage area of the dam’s watershed is 3.2 square miles on Roaring Run. The zoned earth embankment creates a 204-acre reservoir and at normal pool stores 3130 (acre-feet) of water.
The construction of the canal head works began in March 1948, and was completed a year later. Designed as a zoned earth embankment structure with an impervious central core, a semi-pervious layer on either side of the core, and a layer of rock fill. The semi-pervious layer was built in 1 foot (0.30 m) layers and compacted.
The New Waddell Dam is 300 ft (91 m) high from the riverbed and 440 feet (130 m) high from its bedrock foundation. It is a zoned earth-fill type and is 4,700 ft (1,433 m) long; containing 16,200,000 cu yd (12,385,789 m 3) of material. The dam has a crest width of 35 feet (11 m) and a base width of 1,514 feet (461 m). [4]
The dam is a zoned earthfill structure, 41 metres (135 ft) high and 4.5 kilometres (2.8 mi) long. The earthworks contain about 3,870,000 cubic metres (137,000,000 cu ft) of material, including 550,000 cubic metres (19,000,000 cu ft) of clay core from borrow pits and 2,460,000 cubic metres (87,000,000 cu ft) of embankment shell obtained from the ...

The dam was built as part of a major investment in infrastructure required to exploit copper-nickel ore reserves at Selebi and Pikwe, estimated in October 1969 to total 45.7 million short tons. The 3.5 kilometres (2.2 mi) long, 27 metres (89 ft) high zoned embankment was completed in 1973. [1]
