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. The dam's purpose includes flood mitigation, irrigation, water supply, and water conservation.
Location and features
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 Script error: No such module "convert". north of Nundle and Script error: No such module "convert". south-east of Tamworth.[1] Water from the dam is released directly into the Peel River which is used by irrigators downstream of the dam, and for water supply of the city of Tamworth.[2]
The dam wall comprises Script error: No such module "convert". of rock fill is Script error: No such module "convert". high and is Script error: No such module "convert". long. The maximum water depth is Script error: No such module "convert". and at 100% capacity the dam wall holds back Script error: No such module "convert". of water at Script error: No such module "convert". AHD. The surface area of the reservoir is Script error: No such module "convert". and the catchment area is Script error: No such module "convert"..
The dam uses an unusual concrete morning glory bell-shaped uncontrolled spillway which is capable of discharging Script error: No such module "convert"..[2][3][4] The spillway measures Script error: No such module "convert". in diameter and tapers down to Script error: No such module "convert".. The spillway tower is Script error: No such module "convert". high.Script error: No such module "Unsubst".
Chaffey Dam provides valuable public recreation including swimming, sailing, boating and fishing.[2]
Upgrade of facilities
An A$13 million upgrade of Chaffey Dam commenced during 2010 that involved the construction of a Script error: No such module "convert". auxiliary spillway with release plug, funded by the Government of New South Wales and was completed in early 2011.[5] A second stage A$43.33 million augmentation commenced in 2013, funded by the Australian Government, the NSW Government and Tamworth Regional Council. This augmentation is expected to be completed during 2014 and involves raising the dam wall by Script error: No such module "convert". and subsequent works to raise the morning glory spillway and bridge deck. These works will increase the full supply level of the dam by Script error: No such module "convert"., the dam's capacity from Script error: No such module "convert". to Script error: No such module "convert". and ensure it can withstand the maximum possible flood. The project also involves a realignment of roads on the western foreshore; the Tamworth-Nundle Road, and River Road.[6]
Etymology
The dam is named in honor of Frank Chaffey,[1] who represented Tamworth in the New South Wales Legislative Assembly between 1913 and 1940, and his son, [[Bill Nye |Bill]],[1] who represented the same seat between 1940 and 1973.
