Lock 8 and 9 weir pool changes start in August
30 July 2014 - MDBA
River Murray water users and landholders at Lock 8 and Lock 9 can expect changing weir pool heights over the next eight to ten months, and are advised to take action as required.
The changes are part of a trial by the New South Wales Office of Water to introduce variations in the weir pool levels to achieve a more natural wetting and drying cycle for the riverine environment.
The Lock 9 weir pool level is expected to increase by up to 15cm above the full supply level over spring, and the Lock 8 weir pool is expected to increase by about 80cm 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 10cm below full supply level and Lock 8 will be drawn down to about 60cm below full supply level.
Both weir pools will be raised back gradually to full supply level by winter 2015.
The table below outlines the overall plan on a month-by-month basis. These are indicative water levels only; 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 available on the MDBA website at www.mdba.gov.au (http://www.mdba.gov.au).
River users wanting more information on river heights can contact MDBA on (02) 6279 0100 or receive updates at www.mdba.gov.au/river-data/current-information-forecasts/weekly-report (http://www.mdba.gov.au/river-data/current-information-forecasts/weekly-report).
The trial is being conducted by the MDBA in cooperation with the New South Wales Office of Water, SA Water and the Mallee Catchment Management Authority.
