A lock that allows boat passage at Torrumbarry Weir on the Murray River will be drained and refurbished for the first time in more than 20 years.
The temporary closure of Lock 26, scheduled to start on November 8, will not affect the normal operation of Torrumbarry Weir in terms of river flow and water supply.
But recreational water users will be unable to use the lock to travel up or downstream from the first week of November until the end of April next year.
Murray-Darling Basin Authority river management executive director Andrew Reynolds said the closure of Lock 26 would only affect the lock operation and river traffic.
‘‘It is expected that the lock closure will cause minimal disruption to river traffic,’’ Mr Reynolds said.
‘‘This is because the works coincide with passage past Koondrook Bridge, downstream of the weir, being unavailable due to maintenance work to the bridge being undertaken by Roads and Maritime Services.
‘‘We know Torrumbarry Weir is popular with visitors over summer and the closure of the lock will not interfere with fishing, waterskiing or other recreational activities on the river and its foreshore.’’
Goulburn-Murray Water customer operations general manager Scott Barber said the lock was last fully drained and inspected in 1995, when the original Torrumbarry Weir was replaced with a new, modern structure.
‘‘To ensure the lock continues to operate reliably into the future, we need to fully inspect its foundations, concrete and drainage components,’’ Mr Barber said.
‘‘We’ll make repairs as necessary to seals and mechanical parts and apply new protective coating to guard against corrosion.’’
