The Polly McQuinns area proved to be a popular spot for more than just a picnic on Saturday.
Although it was difficult to reach the area because of large debris on the road, many were still able to make it to the weir, which was gushing with water from Mt Wombat.
By Saturday afternoon, Mt Wombat had received 191 mm of rain, which came down through Polly McQuinns.
Strathbogie resident Curtis Hoare lives close to Polly McQuinns and said the last time he had seen it so full was two years ago.
Water spills over a concrete wall at the weir and then travels under a bridge and over large exposed granite boulders.
Mr Hoare said usually the area where the water spilled from was only about a metre wide, but the rain had caused it to expand and run across plants located on the side of the weir.
Polly McQuinns is located on the Seven Creeks and is 4 km southeast of Strathbogie and comprises a reservoir, weir and bridge.
