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 An outdated method of zoned earth dam construction used a hydraulic fill to produce a watertight core.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 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 quoted length of the embankment of 18 km is reliable. The average height of the embankment is quoted to be 40 m, [10] and a check on this using four cross sections [7] yields 45 m, which is of the same order of magnitude. The average base width of the embankment is variously 1,800 m, [10] 800 m from Google Earth and 660 m. [7]
