I have heard that a proposal to considerably extend the capacity of the Wellington Dam is under consideration.

Personally I would very much like to see this work proceeded with, but there is one point which may have been overlooked but which, to my mind, might have been a very serious effect on the ultimate success of the whole venture. I am referring to the possible increases in the salt content of the Collie River following the removal of further timber in the catchment area.”

“SOIL SALINITY

Movement of salt so that it can concentrate and cause bare sterile areas depends on water movement and evaporation, leaving the salt behind. Consequently research officers have studied three main phases of soil moisture movement and use:

1. entry of water into soil on salt patches and adjacent grassed areas;
2. water usage and soil moisture changes under various conditions, especially crop, volunteer pasture and bare fallow;
3. the occurrence of free water (water tables) under flats where salt is a problem, and its possible relation to surface flooding and to underground movement from higher land” [190]

South Australian Country Water Supplies – report by Assistant Under Secretary (to the Minister, Mr Millington)

“… the supply of water [in SA] at these low rates is creating a problem, for the reason that it encourages settlers in South Australia to use water for purposes other than ordinary requirements for which it was intended

… as it is we are forced to discourage the free use of water by charging a high price.

It is, I think, certain that settlers must be further encouraged to go in for mixed farming [wheat and sheep] and so adequate supplies of water must be provided, irrespective of their ability to pay high rates. It is easy to levy a rate which is sufficient to return operating expenses and full Interest, but experiences have proved that it is only possible to collect about one-third of the rates and charges levied [markets] … This Department when undertaking the several agricultural water supply schemes, have always considered each of them as having what is known as a “business undertaking”, but I am now convinced that

1. the rates levied must be reduced to something below a maximum of 6d;
2. the price for excess water should be considerably reduced; and above all, that
3. the source of supply to be reticulated must at all times be reliable and sufficient.

This involves extra Capital expenditure and a reduced direct return on cash to the Treasury but, on the other hand, the indirect return would, I think, be greater than it has been up to date …”

“(iv) Watertable Investigations

observations have continued on a number of sites in which test wells have been placed to observe the watertable fluctuations in valley systems underlain with salt water. In general, these have shown:-

1. In many cases there is a seasonal fluctuation in underground water pressure equivalent to a head of 3 ft of water
2. The hydraulic head measurements in test wells placed across valley systems show that in most cases the hydraulic grade lines slope towards the lower portion of the valley. This would indicate that the underground water movement is from the higher land to the lower land in the valley system.

It seems logical therefore, to postulate in such cases that surface flooding has not been the causal factor of the watertable and, as a consequence, surface drainage will not remove this threat of salt encroachment” [202]

Following farmer concern a survey was conducted in the Collie Irrigation Area (36,700 acre) to define the distribution and extent of saline soils and to determine the possible origin of the salinity. The affected soils are inherently saline showing high levels of soluble salts to depth and are underlain by shallow, saline water tables at 4ft to 7ft below ground level. The water table is confined under slight pressure. High initial levels of salt in the soil profile are the probable cause of salinity problems following development for agriculture.  Some 400 to 500 acres were found to be salt affected within the irrigation area” [237]

Annual Report of the Soil Conservation Service states under:

“Wellington Catchment

The future quality of water from the Wellington Dam could depend on what changes are made in the near future in use of land in the catchment of the dam.

…. Salinity of the dam water fluctuates with rainfall but regular testing of water from Wellington Dam by Public Works Department since 1968 has shown that all samples contained more than 400 mg/L and two in three had more than 500mg/L TDS. The overall trend has been for salinity to increase by 4.3 mg/L TDS per year.

Soils Division officers are helping in several lines of study. Public Works Department regularly samples water from a network of points in the Wellington catchment. Salt and water balance studies are in progress to provide a basis for other research work and decision making” [255]

… Various suggestions have been advanced to halt or reverse the salinisation process: they include partial reafforestation and diversion of saline water from some streams. Selective reafforestation to retain salt stored in the soil profile could be the cheapest approach but the density and species of trees and the areas involved are not yet known.

A survey of farms in the Wellington catchment was carried out at the request of the Environmental Protection Authority. The results showed that a ban on further clearing of alienated land would prevent only a small numbers of farmers from achieving economic viability” [259]

Situation Statement and Salinity Action plan published by WA State Government as blueprint for Salinity Action in WA.  State Salinity Council with Alex Campbell as Chair, Executive and Research and Development Technical group established.  Also proposed were:

1. A formally established inter-agency collaboration, resources and budget ($10M). Large part of this was for tree planting in high and medium rainfall areas.
2. This established the concept of 'priority catchments’ some were Focus (the responsibility of AGWEST) some were Water Quality supervised by the Water & Rivers Commission (W&RC) and some Recovery Catchments (up to 6 were to be established), supervised the Department of Conservation and Land Management (CALM) where remedial action was to be a higher priority, because areas of high conservation value were at risk. The Focus Catchments are where agricultural values are high, or the Catchment Committee is willing to take action.
3. Set up a Ministerial Committee, the “State Salinity Council” (the Council contained formal representation of organisations and many of those nominated had little or no understanding of salinity and CEOs attend these meetings but who did not get to vote), formal meetings of CEOs and Senior Officers and “the Reference Group” which was to advise the Salinity Council, consisting of Chairs of Regional natural resource management committees, together with representatives of conservation groups and other interest groups.
4. The Plan also lead to CALM receiving $s for a biodiversity survey of species at risk (conducted by Greg Keighery).

Revised Draft of the 1996 State Salinity Plan put out for public comment.

Tom Hatton (CSIRO) starts to point out that all the scientific calculations indicate the need for more than 80% of the landscape to be replanted with perennial vegetation if salinity effects were going to be halted (a figure of about 20% had previously been conceived). Richard George (Department of Agriculture) and others supported him.

International Conference on Diffuse Pollution held in Perth.  Paper by R Nulsen questions the impact of the 1996 Salinity Action Plan.

Salinity Council asks the Research and Development Technical Group (RDTG) to model the impacts of the current recharge based options and pumping on salinity.  The RDTG (George, Hatton, Clarke [321]) reviews the impacts recharge based approaches to reduce the eventual extent of salinity, the impacts on flood risk, on biodiversity and develops saltland classes.  Flowtube modelling showed recharge based options were less likely to be effective than first considered, that flood risks would increase by at least two-fold and that native plant and animal extinctions were likely to result from salinity.

Agriculture Western Australia [322] compiles a review of the impacts of trees on groundwaters and salinity.  The study identifies that only large plantings seem likely to influence the current trajectory of salinity.

Western Australian Auditor General releases Report 8 – Management of Salinity – and found 'There is no regular, on-going monitoring and reporting of dryland salinity. As a result, no one accurately knows the extent, impact, cost and potential spread of dryland salinity'. And as a result of poor coordination, 'efforts to manage dryland salinity are unlikely to achieve any landscape wide improvement.' [330]
