THE Queensland Floods Commission of Inquiry will hand down its final report today.
The report is expected to determine whether the government-owned Wivenhoe Dam operator, Seqwater, was to blame for widespread flooding in Brisbane, Ipswich and surrounds in January last year.
The inquiry held extra hearings last month after it was discovered it had missed key documents that cast doubt on what water release strategies dam engineers used.
If Seqwater is found not to have followed the dam manual, it will help lawyers representing up to 2000 flood victims launch a class action against the government.
Commissioner Justice Catherine Holmes will hand the final report to Premier Anna Bligh at 11am (AEST).
Ms Bligh is expected to comment on the report before flying out of Brisbane to campaign ahead of next Saturday's election.
