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 An outdated method of zoned earth dam construction used a hydraulic fill to produce a watertight core.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.
The zoned earth embankment creates a 204-acre reservoir and at normal pool stores 3130 (acre-feet) of water. A normal pool elevation of 1495.3’ is maintained throughout the year via the principal and auxiliary spillways. The zoned earth fill dam is 39 feet in height and 530 feet long.
The dam is an earth-fill type with a length of 4,300 ft (1,311 m) and height of 211 ft (64 m). The dike is 17,000 ft (5,182 m) long and 60 ft (18 m) tall. The dam's main spillway is controlled by three gates and has a maximum discharge of 68,467 cu ft/s (1,939 m 3 /s).
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 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.
Jocassee Dam (often called Lake Jocassee Dam) is an embankment dam on the Keowee River, straddling the border of Pickens and Oconee counties in South Carolina in the United States. The dam forms Lake Jocassee , which is fed by the Toxaway , Thompson, Horsepasture and Whitewater Rivers, and serves primarily for hydroelectric power generation and ...

The reservoir's dam was completed in 1904. It is an earth fill embankment dam, 22.5 metres (74 ft) high, which required some 500,000 long tons (510,000 t) of earth to build. There is a vertical puddle clay core supported by zoned earth fill shoulders. The higher part of the upstream shoulder is faced in dry rubble pitching about 60 centimetres ...
