An improved water level on the River Murray is resulting in increased vessel traffic through the locks.
Traversing a lock is quite simple, so long as a few basic rules are observed. When you are between 600 metres and 400 metres from the lock indicate to the Lock Master your intention to proceed, preferably by using one of the following signals:
- three prolonged blasts (three to four seconds each) on a whistle, portable air horn or other suitable device
- waving a flag
- flashing a light.
Do not approach within 150 metres of the lock until the signal to proceed has been given by the Lock Master – indicated by a green flag or a green fixed or flashing light.
Slowly proceed into the lock. Holding ropes are dropped down in all South Australian locks and should be used to help counter the water surge when the water level is altered inside the lock chamber. Never tie up to anything inside the lock. Wait for the Lock Master to indicate that it is safe to proceed.
