The State Emergency Service flood bulletin said it was likely to reach the minor flood level of 8.8m in Forbes on Saturday, with a forecast height of 9.3 metres on Sunday morning.
Less than two inches of rain has fallen in the region this week but it's been enough in a sodden catchment to fill Wyangala Dam and see flows in the downstream tributaries including the Belubula and Boowra rivers.
On Friday morning the river was at 8.6m at Nanami - near Gooloogong - and rising with minor flooding, with the possibility of reaching the moderate flood level of 9.7m on Saturday.
At Cottons Weir the water was at 4.29 metres and rising with minor flooding, with the possibility of reaching 5.80 metres during Sunday with moderate flooding.

Downstream of Forbes at Jemalong Weir the water was expected to exceed the minor flood level of 7.2m on Friday morning with the possibility of reaching the moderate flood level of 7.5m on Monday.
Wyangala Dam reached 101 per cent on Wednesday night with an anticipated 200 billion litres (gigalitres or GL) in inflows from the rain system.
