In a rare event for the Gwydir area, Copeton Dam has spilled over for the first time in nine years and only the fifth time since it's construction.
It is just one of the dams filling and spilling across the region after days of soaking rain.
Sitting at 99 per cent, the dam has been receiving 30 gigalitres of inflows a day, and more keep coming.

WaterNSW have advised releases from Copeton were increased from 45 megalitres to 5,000ML/day on Tuesday. Its expected these flows could take up to a week to travel along the Gwydir River towards Moree.
But Copeton isn't the only dam filling up quick.
Keepit Dam on the Namoi River is currently sitting at 101 per cent capacity, with spills continuing and adding to the torrent of water surging through the flooded town of Gunnedah.
Large flows from the Peel River are also washing in downstream of the dam and the state water authority is releasing blocks of the wet stuff from Keepit Dam in an effort to limit the effects.
"Water NSW is monitoring rain forecasts and making releases to increase storage capacity to capture inflows as required," a spokesperson said.
Tamworth's main water supply, Chaffey Dam, was gushing over the unique morning glory spillway on Tuesday, at 103 per cent full.
The huge Split Rock Dam was 55 per cent full on Tuesday.
