Within the Angas - Bremer Irrigation Area, the source of the groundwater being taken currently primarily for the large-scale irrigation of lucerne fodder crops is the confined low salinity Tertiary limestone aquifer. The extent of pumping from bores in the area, which irrigates approximately 3000 hectares of crop as mapped in a recent aerial survey, now totals an estimated 25 million cubic metres per year, 64% of which is lost from the tilled soil by evapo-transpiration, the remainder seeping downwards into the shallow, more saline, unconfined aquifer. There is no direct access of surplus irrigation water to the underlying confined aquifer. The present over-use of the lower aquifer does, however, encourage seepage of the more saline groundwater of the upper aquifer into the lower aquifer. Declining static water levels, together with representations from local irrigators, have stimulated the Government to undertake investigations of the aquifer systems to determine the safe, long term yield of the groundwater resource. The Angas-Bremer Water Resources Advisory Committee has assisted at all times in these investigations. The present report outlines the history of irrigation practice in the region, and describes the present level of knowledge of the aquifer system, including its current behaviour with regard to standing water levels, salinity, measured bore yields and the natural ingress of water, both fresh and saline, coming from outside of the system. A theoretical analysis is made of the distribution of water quality within the two aquifers, and the influence thereon of likely existing natural recharge zones. Information obtained recently by the SADME authors from their conduct of a single-well water injection and (subsequent) extraction test, plus other anecdotal evidence that they have obtained from local farmers about the performance of two existing private recharge bores, has indicated that it is worth attempting to artificially perform significant further recharge to the confined aquifer, preferably near the centre of the water table's cone of depression, by using purpose-made bores to be located in swamps or adjacent to the two rivers. Eleven swamps were inspected during October 1980, which could possibly be drilled to effect such recharge, but it was recommended that the selection of suitable well sites should be made where there is control over the frequency of swamp flooding arising from natural causes, to be exerted via the opening of weirs or floodgates constructed in existing riverbank mounds and floodplain dykes.
