Recent routine inspections identified damage to the downstream gate seal requiring essential maintenance.
MDBA Executive Director River Management, Andrew Reynolds, said Lock 9 is an important weir for managing Lake Victoria storage levels. The maintenance work is being done at this time to mitigate against lock closures during peak recreational periods.
The Weir and Lock 9 is also critical in diverting water into Lake Victoria. It is prudent to undertake this work now to ensure there is no impact to Lake Victoria storage level.
"The temporary closure will not affect the normal operation of the weir in terms of river flow and water supply; however, recreational water users will not be able to use the lock to travel up and down the river," Mr Reynolds said.
"The weir pool level will remain at normal operating levels throughout the work."
In accordance with the longstanding Murray–Darling Basin Agreement, River Murray Operations assets are owned by a 'Joint Venture' comprising of State and Federal Governments.
The MDBA is tasked to operate the River Murray system on behalf of the 'Joint Venture'. SA Water is the nominated State Constructing Authority responsible for operating and maintaining Lock 9 under the direction of the MDBA.
Further updates will be provided if there are any changes to the closure dates.
