The Isis Balancing Storage is a small earth-filled embankment dam across an unnamed tributary of the Elliott River, located between Bundaberg and Childers in the Wide Bay-Burnett region of Queensland, Australia. Completed in 1986, the impoundment created Lake Gregory, also known as The Duckpond,[1] that was built to provide irrigation water to farmers on the Isis channel system.[2]
Overview
The dam wall is 14.2 metres (47 ft) high, 721 metres (2,365 ft) long, 6 metres (20 ft) wide at the crest, and holds back 6,440 megalitres (5,220 acre⋅ft) when at full capacity. The small reservoir is 1.67 square kilometres (0.64 sq mi) in area, with an average depth of 3.1 metres (10 ft) that draws from a catchment area of 12.8 square kilometres (4.9 sq mi).[2]
In 1991, the reservoir was stocked with 80,000 bass and 25,000 Silver Perch. Garfish and eel-tailed catfish occur naturally.[3] Lake Gregory is the closest freshwater storage lake to Bundaberg and is surrounded by the Elliott State Forest.[4] A Stocked Impoundment Permit is required to fish in the dam.[5]
