Weir pool level changes at Lock 8 and Lock 9
21 August 2013 - Murray Darling Basin Authority
River Murray water users at Lock 8 and Lock 9 can expect changing weir pool heights over the next 8 to 10 months as part of a NSW river operations trial.
Water users and landholders are advised to check the planned pool variations, and take relevant action as required.
The Lock 9 weir pool level is expected to increase by up to 25cm above the full supply level over spring, and the Lock 8 weir pool is expected to increase about 60cm above full supply level.
Over summer and autumn, the weir pools will be lower than full supply level.
Lock 9 is expected to be drawn down to about 40cm below full supply level and Lock 8 will be drawn down to about 50cm below full supply level.
Both weir pools will be gradually raised back to full supply level by winter 2014.

The table above outlines the overall plan on a month-by-month basis. These are indicative water levels, therefore actual river operations may differ.
The MDBA will issue a revised flow advice if there are any significant changes to the plan which will also be made available on the MDBA website at www.mdba.gov.au (http://www.mdba.gov.au).
This trial is being undertaken in co-operation with the NSW Office of Water and Mallee Catchment Management Authority.
