Groundwater

Mantinea Plain hydrogeological investigation preliminary results

The Western Australian Government is investigating the feasibility of extending the Ord River Irrigation Area to accommodate an increased demand for irrigation land. This report presents the hydrogeological information available to date on the Mantinea Plain to assist in irrigation development planning. The report recommends that, to complete the study on Mantina Plain, drilling be undertaken to clearly define the extent and thickness of sediments beneath the Plain, and to define the water table configuration, and the distribution of groundwater salinity (A).

Introduction (Groundwater and Water Management in the Ord River Irrigation Area)

This paper deals with irrigation farming and changes in groundwater in the Ord River Irrigation Area WA. The ORIA and its water resources are described. The salt tolerance of crop species is discussed and the need for efficient irrigation and scheduling of irrigation noted.

Groundwater studies in the Ord irrigation area, recent developments ;

Much of the Ord Irrigation Area requires careful management to prevent problems with high groundwater levels and subsequent water- logging of crops and secondary soil salinisation. Management means controlling and reducing artificial groundwater recharge which may occur because of leakage of irrigation system waterways or excessive application of water to crops. The areas developed so far have shown varied but predictable responses to this artificial recharge. Irrigation activity is unlikely substantially to change groundwater levels.
