The zoned earth embankment creates a 204 acres (83 ha) reservoir and at normal pool stores 3,130 acre-feet (3,860,000 m 3) of water. A normal pool elevation of 1,495.3 feet (455.8 m) is maintained throughout the year via the principal and auxiliary spillways. The zoned earth fill dam is 39 feet (12 m) in height and 530 feet (160 m) long.
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 An outdated method of zoned earth dam construction used a hydraulic fill to produce a watertight core.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.
