Abstract / Summary:
CSIRO Land and Water Technical Report 26/99
The medium to long-term viability of large irrigated areas in the Riverine Plain region of Victoria and NSW is closely linked with management of high water tables. Restrictions imposed by the Murray-Darling Basin Salinity and Drainage Strategy have led to reductions in the export of salt from the area where it originated. These restrictions have resulted in an increase in the number of local on-farm and community disposal basins in irrigation areas. The existing design and management of both types of basin vary widely as they have been developed under different administrative framew o rk s . Currently there are no generic guidelines for the use of disposal basins which could be applied across varying settings and administrative boundaries.
For the last two years, CSIRO Land and Water in collaboration with the CRC for Catchment Hydrology, the Murray-Darling Basin Commission (Strategic Investigation and Education Program, Project I7034 Managing Disposal Basins for Salt Storage Within Irrigation Areas) and other agencies have been investigating the siting, design and management conditions under which local basins can be successfully used by individual landowners or groups of landowners. The biophysical and other technical information obtained in this project have been used to define a robust set of guiding
principles
for responsible basin use.
A workshop entitled "The Use of On-Farm and Community Scale Salt Disposal Basins in Irrigation Areas of the Murray-Darling Basin" was conducted in March 1999 at Tatura, Victoria. The workshop was attended by about 40 people representing a wide range of stakeholder groups such as government resource and policy agencies, community and environmental groups, water supply corporations and local government. A set of principles on disposal basins was put forward by the project team and the thrust of this was generally accepted by the workshop. In addition, several new issues were raised, some of which were broader than the scope of the project. The w o rkshop also proved to be an effective forum in which technical information from the project was transferred to prospective clients. A list of workshop participants, slides from the formal presentations and a summary of workshop comments are given in the Appendices.
The principles developed in this document should be considered, where appropriate, within the framework of existing Catchment Land and Water Management Plans, and State, Federal and Local Government regulations. However, it should be emphasised that these principles define desirable conditions for basin use in a general manner and should not in any way be considered as specific policy, regulation or law.
