The Bureau of Meteorology is now anticipating the Lachlan River will peak "near" the major flood level but below 2016 levels at the Iron Bridge today (Wednesday).
In the bulletin issued by SES at 10am Wednesday, the authority said river levels have continued to slowly rise along the Lachlan River at Forbes Iron Bridge and "are likely to peak near the major flood level".
This is just below the September 2016 flood level.
Major flooding is also likely at Cottons Weir later today and at Jemalong on Thursday.
The Bureau advises, as of 10am Wednesday:
Moderate flooding is occurring at Forbes and Cottons Weir. Major flooding is occurring at Nanami. Major flooding is expected at Forbes, Cottons Weir and Jemalong.
The Lachlan River at Nanami peaked at 12.45 metres around 10:00 pm Monday and is currently at 11.74 metres and falling with major flooding.
The Lachlan River at Forbes Iron Bridge may peak near 10.55 metres during Wednesday with major flooding, just below the September 2016 level.
The Lachlan River at Cottons Weir may peak near 6.60 metres during Wednesday with major flooding, just below the September 2016 level.
The Lachlan River at Jemalong Weir Downstream is expected to exceed the moderate flood level (7.50 m) Tuesday evening.
The river level is likely to reach the major flood level (7.70 m) during Thursday. Further rises are possible and a peak prediction will be made once upstream peaks are observed.
