Publications and NoticesNotice to Mariners No. 20 of 2021 (Temporary) (Cancelled 20/12/2022)
Monday, 19 July 2021
HARBORS AND NAVIGATION ACT 1993
SOUTH AUSTRALIA – RIVER MURRAY – RAISED POOL LEVELS
Mariners are advised that the Department of Environment and Water are carrying out floodplain environmental water operations during the coming weeks which will temporarily raise the River Murray water levels in the weir pools above locks 4 and 5. This will commence from Late July 2021 and will include operating the environmental regulator structures on the Katarapko and Pike Floodplains.
The exact height will depend on the flow and conditions within the river and the Katarapko and Pike Floodplains.
Mariners should proceed with caution in the areas described above due to the increased risk of submerged hazards, changed bridge clearance heights and other overhead hazards, in particular at the Gurra Gurra Bridges located at approximate location 34° 18’ 53.78” S 140° 36’ 22.20” E.
Mariners may also need to adjust moorings.
All queries should be directed to the Communications Officer, Water Infrastructure and Operations, Department of Environment and Water, on mobile 0403 933 811.
