The Challenge

Water for Rivers, working with the New South Wales State Water Corporation and other New South Wales government departments, wanted to identify and investigate improvements to water delivery operations capable of producing water savings in the Murrumbidgee River system as a part of its Murrumbidgee River Efficiency Project. This study formed one of several components of this project. It reviewed the adequacy of the current rainfall and stream gauging station coverage and the technology used for the capture and transmission of data from these stations for forecasting of Murrumbidgee River tributary inflows for efficient operation of the river.

Improved and timely forecasts of tributary inflows into the Murrumbidgee River together with other efficiency measures for day-to-day river operations would provide substantial water ‘savings’ by requiring less water to be released from Burrinjuck and Blowering Dams to meet customer needs.

Approach and Key Activities

The study team met representatives of key stakeholder organisations to discuss and better understand what data and information they collect, provide or receive and how they use that data and information. During these meetings, views of operational staff on potential improvements that can be made to the benefit of river operational decision making were also canvassed. Discussions and meetings were held with representatives from Water For Rivers, State Water Corporation, NSW Office of Water and Bureau of Meteorology.

Outcomes

The study made a number of recommendations to enhance the rainfall and stream gauging station coverage and improve the tributary inflow forecasting methodology to improve the performance of the State Water Corporation’s Murrumbidgee River Water Management system.

It is understood that most of the recommendations of this study have now been implemented.
