Groundwater Management Unit: Condamine - Condamine Groundwater Management Area Sub-Area 2

Introduction

The Condamine River is located on the western side of the Great Dividing Range and is the main drainage of the Condamine Basin (4223). There is particular groundwater interest in the alluvial aquifers associated with the Condamine River. An area of high priority has been defined within the alluvium and is known as the Condamine Groundwater Management Area (CGMA). The CGMA is divided into five sub-areas. The Condamine (CGMA) Sub-area 2 GMU is located in the Wambo and Jondaryan Shires and includes the Parishes of Greenbank, Hill and Weale. It extends over an area of 500 sq km. The town of Dalby and the township of Cecil Plains are located outside but in close proximity to the GMU. The GMU is drained in a north westerly direction by the Condamine River to which the eastern extent of the GMU is bound. The major tributary streams include Spring and Myall Creeks.

Groundwater extracted from the alluvial aquifers is used predominantly for irrigation and town water supply with minor consumption for domestic and stockwatering supplies. Groundwater is of variable quality and is generally suitable for most purposes. Irrigators have been using surface water supplies from the Condamine River in conjunction with groundwater supplies to provide enough water for large-scale irrigation developments.

The GMU experiences a temperate climate with an average annual rainfall of approximately 635 mm a year. Approximately 67% of rainfall occurs between the months of October and March, inclusive.
