Water resources - Management and Development - Western Australia
Basin & Surface Water Management Area: Ashburton River
Introduction
As resource demands and pressure increases so to do the requirements of both management and information needs. Outlined below are the key issues facing the region as determined by the State / Territory water management agency.
What is the estimated demand for surface water in Ashburton River?
| Use and Sustainable Yield | |
|---|---|
Comment about sustainable yield figure: | Estimation of sustainable yields was undertaken as a two stage process. The first stage, or first cut, involved accumulating sub area data to the SWMA scale, for the likely development scenario. This development scenario included applying all constraints explicit or strongly implicit in established regional allocation plans, policy or regulations, in the selection of preferred sites. First cut sustainable yields were then estimated based on applying management objective factors to each sub area, to determine sustainable yield from divertible yield where more detailed environmental flow requirements had yet to be determined. The second cut refinement aimed to provide allowances for regional reservations yet to be established. While the second cut involved subjectivity, the refinements made were based on accumulated regional planning experience, and are believed to reflect realistic outcomes at SWMA levels. |
