Chaffey Dam is a minor ungated rock fill with clay core embankment dam with an uncontrolled morning glory spillway across the Peel River, located upstream of the city of Tamworth, in the New England region of New South Wales, Australia.

Commenced in August 1976 and completed in September 1979, the Chaffey Dam is a minor dam on the Peel River, a tributary of the Namoi River, approximately 16 kilometres (9.9 mi) north of Nundle and 44 kilometres (27 mi) south-east of Tawmorth.

The dam uses an unusual concrete morning glory bell-shaped uncontrolled spillway which is capable of discharging 903 cubic metres per second (31,900 cu ft/s).

[citation needed] Chaffey Dam provides valuable public recreation including swimming, sailing, boating and fishing.

[2] An A$13 million upgrade of Chaffey Dam commenced during 2010 that involved the construction of a 35 metres (115 ft) auxiliary spillway with release plug, funded by the Government of New South Wales and was completed in early 2011.
