Observations Of Shallow Groundwater Contamination Due To Leakage Of Dairy Effluent Ponds On The Swan Coastal Plain, Wa, Richard J. George Dr, D L. Bennett, J R M Bell, Roger Wrigley Oct 1999

Observations Of Shallow Groundwater Contamination Due To Leakage Of Dairy Effluent Ponds On The Swan Coastal Plain, Wa, Richard J. George Dr, D L. Bennett, J R M Bell, Roger Wrigley

Resource management technical reports

In response to the risk of pollution of surface water from farm runoff, dairy farmers have been encouraged to install effluent storage ponds. Previous research has indicated that leachate from these storages can contribute to groundwater contamination. This project assessed the performance of storages at eight sites on the Swan Coastal Plain (SCP), WA. Groundwater conditions were monitored for over three years to study the influence of soil type, water table depth and waste water characteristics.

The Translocation Of Barramundi. A Discussion Paper., Makaira Pty Ltd Jul 1999

The Translocation Of Barramundi. A Discussion Paper., Makaira Pty Ltd

Fisheries management papers

There is recognisable economic benefit to the translocation of barramundi, but there is also a need to ensure the translocation will not adversely impact upon the genetic diversity, introduce disease or impact on the natural environment and biodiversity. This discussion paper has been prepared to provide information to assist in the assessment of the possible impact of translocation of barramundi into and within Western Australia, for the purposed of recreational stock enhancement, aquaculture development and domestic stocking. In contemplating the translocation any aquatic species, signigicant economic and social benefits must be balanced with biological and environmental risks; that is, the …

Fisheries management papers

This discussion paper proposes a way for the South Coast Estuarine Fishery to address issues relating to the long-term sustainable management and sharing of the fish resource.


Proposals For Community Discussion. A Quality Future For Recreational Fishing In The Gascoyne. A Five-Year Management Strategy For Recreational Fishing., Gascoyne Recreational Fishing Working Group May 1999

Proposals For Community Discussion. A Quality Future For Recreational Fishing In The Gascoyne. A Five-Year Management Strategy For Recreational Fishing., Gascoyne Recreational Fishing Working Group

Fisheries management papers

Gascoyne has seen a series of rapid developments in recreational fisheries management, starting with the introduction of state-wide bag limits in 1991; followed by area specific controls at Ningaloo in 1992; landing limits in Exmouth Gulf in 1993; strict controls on the take of pink snapper in Shark Bay’s inner gulfs in 1997; new bag limits for Shark Bay in 1998; and the introduction of a management system for the charter and aquatic tour industry in 1999. The management proposals presented for community discussion in this paper are aimed at maintaining or improving the quality and diversity of the Gascoyne's …


Coastal Land And Groundwater For Horticulture From Gingin To Augusta, Dennis Van Gool, Werner Runge May 1999

Coastal Land And Groundwater For Horticulture From Gingin To Augusta, Dennis Van Gool, Werner Runge

Resource management technical reports

Due to a variety of factors, including infrastructure needs, labour requirements and transport costs, horticulture is often located near major urban centres. This study focuses on the coastal plain region from Gingin to Augusta. This region accommodates over 80% of Western Australia’s population and includes the State’s major urban centres. This region accounts for over half the State’s horticultural production with a gross value of production of $244 million (adjusted ABS values, see section 1.2). Increasing population pressures and increasing demand for horticultural produce have resulted in competition for the limited land resources in this area.


Salinity And Hydrology Of The Fence Road Catchment : A Focus Catchment Of The Blackwood Basin, Ben Whitfield Jan 1999

Salinity And Hydrology Of The Fence Road Catchment : A Focus Catchment Of The Blackwood Basin, Ben Whitfield

Resource management technical reports

It is the clearing of native vegetation and replacement with lower water-use annual crops and pastures that is responsible for the developing salinity problem. Traditional farming practices have led to increased recharge to the groundwater systems resulting in increased storage and/or greater areas or rates of discharge. Groundwater monitoring has revealed variable rates of rise throughout the Fence Road catchment, from static to 0.6 metres per year, in a period of average to below average rainfall.
