Assessing Storage Reliability Of Farm Dams, D Farmer, N Coles
Resource management technical reports
This report provides information on a method to estimate the volume of water in a farm dam and to determine how long this water will last. During periods of low rainfall, dams with farmland catchments receive limited run-off. Alternative water sources or management strategies need to be considered before the water runs out. The methods provided in this report are intended to provide to the landholder an indication of water supply over short periods only (i.e. in the order of 4-20 weeks).

Scott Coastal Plain A Strategy For A Sustainable Future, Department Of Agriculture And Food, Western Australia
Bulletins 4000 -
The Scott Coastal Plain has significant attributes that make it an area of State and regional significance for agricultural production. The climate, availability of good quality groundwater for irrigation, and large lot sizes provide opportunities for mechanised horticultural production which other parts of the State may not have.
An estimate of the area that could be used for each agricultural land use has been developed, at a broad study area level. The figures presented in this report show that diversified production combining tree plantation and/or irrigation (cropping or hay/silage) with grazing enterprises provides for potential increases in gross margins and …

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 normally located near major urban centres. This study focuses on the coastal plain region from Gingin to Augusta. This region accomodates over 80% of Western Australia's population and includes the States major urban centres. This region also accounts for over half the State's horticultural production with a gross value of production of $244 million.
A Review Of Four On-Farm Water Supply Demonstration Farms, M H M Casey, I A F Laing
A Review Of Four On-Farm Water Supply Demonstration Farms, M H M Casey, I A F Laing
Resource management technical reports
In March 1982, the Western Australian Government allocated $100,000 to the Department of Agriculture to demonstrate appropriate, reliable, on-farm conservation technology on four farms in the north-eastern wheatbelt. The Government grant was matched dollar for dollar with the farmers funds with a maximum of $25,000 grant to any one farm. The demonstrations used existing techniques, such as dams and roaded catchments, to establish permanent drought-proof water supplies.
Influence Of Water Supply On Farm Productivity In The North-Eastern Wheatbelt, E J. Hauck
Influence Of Water Supply On Farm Productivity In The North-Eastern Wheatbelt, E J. Hauck
Resource management technical reports
In the area with reliable reticulated water supplies, average what yield, average wool production and average number of sheep per pastured hectare showed a positive correlation with annual rainfall in all but one year. By contrast, in the area served by on-farm water supplies only, average wheat yield and annual rainfall were strongly correlated, whereas average wool production and average number of sheep per pastured hectare showed a weaker correlation with annual rainfall. These correlations suggest tt on farms with a reliable water supply, livestock numbers have been adjusted annually to ensure optimum utilisation of available feed in all seasons.
Drainage Of Sandplain Seeps For Salinity Control And Stock Water Supplies, Richard George, Peter Frantom
Drainage Of Sandplain Seeps For Salinity Control And Stock Water Supplies, Richard George, Peter Frantom
Journal of the Department of Agriculture, Western Australia, Series 4
Sandplain seeps are derived from a shallow groundwater system which flows from the deep sandplain soils upslope. Seeps result in small areas of salinity and waterlogging, which can be the focus of soil erosion. Sandplain seeps may represent as much as 10 per cent of Western Australia's salt problem in the drier agricultural area. Several drainage experiments conducted between 1986 and 1989 determined the best methods of reclaiming sandplain seeps.
This article discusses the results of these drainage experiments. It comments on the most suitable method for reclaiming sandplain seeps and developing them for stock water supplies.

Water Supplies : Dams And Roaded Catchments, W J. Burdass, T. R. Negus, A. L. Prout, I. A. F. Laing
Journal of the Department of Agriculture, Western Australia, Series 4
Western Australia's Upper and Lower Great Southern statistical areas include most of the broad-scale agricultural land south of a line from Perth to Hyden. Much of the area is well-developed and carries 13.4 million sheep, 203 00 cattle and 95 000 pigs, almost half the State's livestock.
There are few natural rivers and lakes to water livestock in summer and much of the bore water is salty. On-farm waterr conservation, therefore, consits mainly of excavated earth tanks (dams) which are filled by surface runoff or shallow seepage. In the drier areas and in the sandplain roaded catchments have neen built …
Northern Wheatbelt Water Supply Study, I A F Laing, R. M. Pridham
Northern Wheatbelt Water Supply Study, I A F Laing, R. M. Pridham
Journal of the Department of Agriculture, Western Australia, Series 4
Department of Agriculture surveys have shown that many farms in Western australia's northern wheatbelt have inadequate water supplies. More than 80 per cent of all farms in that area depend soley on groundwater for watering livestock, a much higher percentage than for most other farming areas. Because groundwater salinities have increased in recent years, concern is held for the long-term future of this recource.
In contrast to more southern agricultural areas, farm dams in the northern wheatbelt are relatively uncommon. Only 30 per cent of the existing dams in the northern wheatbelt constitute effective water supplies. More than half of …
Underground Water Supplies In The Wheatbelt, T T. Bestow
Underground Water Supplies In The Wheatbelt, T T. Bestow
Journal of the Department of Agriculture, Western Australia, Series 4
Underground water originates from rainfall. The size of the underground recource in any region is broadly related to the amount of rainfall. However, rainfall intensity and seasonal distribution are just as importent as the quality. A relatively small annual fall which consists of a series of heasvy showers or storms close together, may be a more effective source of recharge to underground water than a larger fall that is more evenly distributed over a longer period.
A large annual rainfall, however, is no guarantee that underground water supplies will be readily available. This is because soils and the underlying rocks …

Curbur Station : Inventory Of The Range And Its Management, Alexander Mcrae Holm
Resource management technical reports
Ten land systems were identified, descriped and mapped. potential feed status was assessed for each land system. The land systems were then ranked accordingly and stocking rates allocated. Wongdong saline shrublands was considered to be the most productive system and Narryer hills, outcrops and breakaways the least productive. An assessment was made of the range condition and erosion status of the least. These assessments indicated that most of the pastures had been heavily utilized in the past.

Cereal, Pasture Legume And Water Supply Prospects At Forrestania : Results Of Experimental Work East Of Hyden, Western Australia, T E. Mcdowell, M G. Mason, J W. Gartrell, William J. Toms, I A F Laing
Technical Bulletins
The agricultural potential of the Forrestania area appears at least equal to that of much of the settled eastern wheatbelt. The scrubplain soils of the Forrestania area have an average yield potential of at least 1 000 kg/ha wheat and carrying capacity of 1.8 to 3.7 sheep per hectare on improved pastures. The use of clover ley rotations would maintain these levels of potential yield. Partial crop failures caused by adverse seasonal conditions could be expected 10 years in every 100.

P.W.D. Supplementary Public Water Supply Schemes, J E. Davis
P.W.D. Supplementary Public Water Supply Schemes, J E. Davis
Journal of the Department of Agriculture, Western Australia, Series 4
Shallow wells and soaks with very limited yields were the principal water sources for the early settlers.
Hundreds of such wells were constructed by the Public Works Department in remote areas.
In the early 1930s major development of water supplies from rock catchments was begun in the central wheatbelt.
After the war, larger and more effective earth moving equipment became available. The Public Works Department rehabilitated many old excavated dams as well as constructing new ones.
Roaded catchments were also developed during this post-war period. many farmers took advantage of Public Works Department technical advise and hired a P.W.D. grader …

Farm Dams In The Wheatbelt, I A F Laing
Journal of the Department of Agriculture, Western Australia, Series 4
Of the estimated 76 000 farm dams in the wheatbelt, about 8 per cent either leak or are salt affected. The remaining 70 000 dams are capable of holding water for livestock use and can be regarded as sercicable dams.
A great many of the serviceable dams are unreliable water supplies due to the combined effects of lack of runoff from catchments, shallow depth of storage and small size of storage in relation to expected demand from livestock and evaporation loss.
