The search of the Clutha River for Paul Wilson (28) of Roxburgh is to continue towards the end of the week, as existing river levels make searching difficult.
Search and rescue staff and private searchers continued exploring the Clutha River and shoreline over the weekend with no success.
"The best conditions for searching are when the river is at a lower level. Given the large amount of rain that has fallen, the river is running high. Contact Energy is working with Police to consider the possibility of lowering the river to minimum levels towards the end of the week," said Detective Sergeant Derek Shaw who is leading the search effort.
Mr Wilson went missing last Wednesday around midday at the Talla Burn stream near Beaumont.
Detective Sergeant Shaw said the volume of water flowing through the river towards the end of the week would determine the direction and approach the search would take.
