Catchment History

The Gillamii Centre is based in the Kent Frankland subregion within the South Coast region of Western Australia, covering a total area of more than 541,629 hectares. The subregion is situated in the geographical area of the Cranbrook and Broomehill-Tambellup Shires where the upper catchment systems flow through the Gordon-Frankland River, Kent River and the internally draining local lakes system.

Balicup Wetlands Suite – Resource Condition Report for a Significant Western Australian Wetland Balicup Lake 2009

Balicup Lake was selected as a study site in the IAI RCM project as it is recognised as part of a nationally significant wetland system, by being listed in the Directory of Important Wetlands in Australia (DIWA) (Environment Australia 2001).

Kent River - Salinity Situation Statement 2007

Water in the Kent River was once fresh (salinity below 500 mg/L TDS) but by the 1960s the salinity exceeded 500 mg/L (marginal quality) without further land use changes in the catchment. This report analyses where and why the river water became so saline, describes the current salinity situation, and highlights the scale of intervention required to reduce its salinity.

Gordon-Frankland Area: Catchment Appraisal 2003

Soil degradation on farmland reduces agricultural production and damages infrastructure and natural resources such as remnant vegetation, waterways and wetlands. While dryland salinity, waterlogging and soil erosion cause serious environmental problems in Australia, several other forms of soil degradation are of concern such as water repellence, wind erosion and soil acidity.

Kent River – Hydrogeomorphology and Hydrogeology of the Upper Kent River Catchment and its Controls on Salt Distribution and Patterns of Groundwater Discharge 1997

As one of the five national program focal catchments, the Ken Catchment has provided an opportunity for new methodologies to be developed for landscape mapping, hydrogeomorphic classification and hydrogeological characterisation. Detailed knowledge of these features is basic to development of management practices to control surface water and groundwater movement.
