The Fitzroy River at Riverslea reached its major flood level of 24m at 9am on Sunday, but has since moved to 25.6m.

BoM hydrologists are not yet sure how the Riverslea will surge once the water that is currently bringing major flooding to the lower reaches of the Mackenzie River arrives.

Two other major rivers which feed the Fitzroy, the Issac and Connors rivers, have already receded to moderate flooding after days of major flooding that tore through Central Queensland, with much of the water moving into the Fitzroy.

The Fitzroy River at Yaamba exceeded the moderate flood level of 12m at midday on Sunday and surged to 12.65m by 6pm.

UPDATE: 3.54pm:

FLOODING in two major rivers feeding the Fitzroy River has receded to moderate flooding as water races down the catchment.

The Connors and Isaac River now have a moderate flood warning after days of major flooding, BoM's latest warning reveals.

The warning states that the "lower reaches" of the Mackenzie River are now in major flooding after smashing the record at Tartrus.

MAJOR FLOODS: The Fitzroy River at Riverslea now at major flooding.

Significantly, the Fitzroy River at Riverslea, a major junction where two other rivers meet the Fitzroy, has surged to 24.9m this afternoon, above the major flood level of 24m.

"The main flood peak in the Fitzroy is now approaching Riverslea," BoM's warning states, adding it is expected to peak tomorrow morning.

BoM and authorities have said the peak at Riverslea will give a better idea of the peak for Rockhampton.

The Fitzroy at Rockhampton is expected to exceed a minor flood level of 7m by tomorrow morning, a major flood level of 8.5m on Tuesday morning, and a peak of about 9.4m on Wednesday night or early Thursday morning.

6.30am: Hydrologists are closely watching a Fitzroy River flood gauge about 200km upstream from Rockhampton as the city waits for a major flood peak that could be as high as the 1954 event of 9.4m.

The prediction will be updated when the peak is reached at Riverslea where the level was at 23.22m at 5.40am and steady.

The Bureau of Meteorology last night that a major Fitzroy River flood peak was expected at Rockhampton around Wednesday and was likely to be larger than the 2011 flood of 9.2m and may reach the February 1954 level - the city's second highest behind the 1918 record of 10.1m.

The peak at Riverslea in 2011 was 27.38m

At 6am the Fitzroy River at Yaamba 36km north of Rockhampton was rising fast at 11.6m and expected to exceed the moderate flood level (12.m) during Sunday. The river level is likely to reach the major flood level (15m) on Monday evening.

The Fitzroy River at Rockhampton was at 5.4 metres at 6am and expected to exceed the moderate flood level (7.50m) overnight Sunday into Monday.

The river level is likely to exceed the major flood level (8.50m) late Monday afternoon and forecast to peak between 9m and 9.4m during Wednesday.

The main flood peak in the Fitzroy system is now in the Mackenzie River where record heights have been reached downstream of Coolmaringa and will move downstream over the next week.

10pm Saturday: Flood warning for the Fitzroy system

Dawson River downstream of Theodore:

Minor to moderate flooding is occurring along the Dawson River between Beckers and Knebworth.

No river level readings are available for the Dawson River at Baralaba (manual gauge). Based on river levels at the automatic station at Baralaba Weir it is likely that levels are below the minor flood level (4.00 m) but with renewed rises occurring. The river level may exceed the minor flood level (4.00 m) during Sunday.

Don and Dee Rivers:

Minor flood levels are easing in the Don River at Rannes and in Callide Creek at Goovigen.

Connors and Isaac Rivers:

Moderate to major flood levels are easing along the lower reaches of the Connors and Isaac Rivers.

There is very limited data available due to station and communication failures.

Major flood levels are expected to be occurring on the Isaac River at Yatton. Major flooding will continue well into next week.

Mackenzie River:

Record major flooding is occurring along the lower reaches of the Mackenzie River.

The Mackenzie River at Tartrus is currently at 16.82 metres and falling. A peak of 18.26 metres was recorded at 3 pm Friday, which is higher than the previous record of 18.19 metres recorded in 1958. The Mackenzie River at Tartrus will remain above the major flood level (15.00 m) over the weekend.

Flood Safety Advice:

Remember: If it's flooded, forget it. For flood emergency assistance contact the SES on 132 500. For life threatening emergencies, call Triple Zero (000) immediately.

UPDATE: 8.03pm, Saturday

A MAJOR river height gauge in the Fitzroy River has begun to surge, Bureau of Meteorology charts show.

The Fitzroy River at Riverslea, at the junction of two major rivers that feed the Fitzroy, has rapidly risen on Sunday to 20.02m tonight, well above the minor flood level of 15m.

BoM hydrologists in their latest warning said the Fitzroy at Rockhampton would exceed a moderate flood level tomorrow night.

Mayor Margaret Sterlow said the Fitzroy River at Riverslea would be a key indicator of whether Rockhampton could expect the flood to exceed the current prediction of 9.4m.

"We'd never say no (it couldn't get higher than 9.4m), but we do have a high degree of confidence," she said.

"Until it passes Riverslea we are not 100 per cent certain, but there is a high level of agreement now with the Bureau (of Meteorology), with every hydrologists that we know of and we have spoken.

"We would love it to come in a little bit lower, but I am not anticipating anything dramatically higher."

BOM hydrologists are watching this tiny section of the Fitzroy closely.

BoM hydrologists are also concerned about a sustained major flooding in the Connors, Isaac, and Mackenzie, all of which feed the Fitzroy River.

The Fitzroy at Yaamba, which is expected to flood the small town by Monday, has now surged to 10.7m, well above the minor flood level of 9m.

UPDATE: 1.25pm:

A CRUCIAL river which feeds the Fitzroy at Rockhampton is sustaining a "major flood level" until well into next week.

The Mackenzie River at Tartrus, which smashed the 1991 record of 18.11m yesterday with a stunning 18.27m peak, has become a flash point for Bureau of Meteorology hydrologists predicting when the Fitzroy will peak.

The length of time the Mackenzie remains at a major level, means the Fitzroy River, which is predicted to peak at about 9.4m on Wednesday, could sustain a major flood level for a significant period.

YESTERDAY: UPDATE: 2.43pm:

THE MACKENZIE River at Tartrus has become a flashpoint for flood predictions for the Fitzroy River.

The Mackenzie is one of four major rivers that feeds the Fitzroy.

The Mackenzie, which entered the "major flood" threshold at 15m, continues to rise after smashing the 1991 flood record, sitting at 18.27m as of 1.45pm, a slight fall from 1.30pm when it was at 18.29m.

RISING: The Mackenzie River at Tartrus continues to rise after smashing the 1991 flood level.

Hydrologists at the Bureau of Meteorology are closely watching the Mackenzie at Tartrus as it continues to rise well-above the 1991 record of 18.1m.

The Bureau were initially forecasting the Mackenzie to peak at 18.11m, but it continues to surprise.

BREAKING: 1.58pm:

A MAJOR flood in a key river that feeds the Fitzroy has smashed the 1991 record.

The Mackenzie River at Tartrus is currently at 18.24m, smashing the previous record of 18.1.

A "major flood" is 15m, according to the Bureau of Meteorology.

UPDATE: 12.16pm:

BUREAU of Meteorology river height gauges reveal a key river that runs into the Fitzroy River is about to hit a record flood level.

The Mackenzie River at Tartrus smashed the 1954 record of 17.48m in 1991 when it hit 18.1m.

The latest BoM warning predicts it will reach 18.11m. It has just exceeded 18m today.

>>WATCH LIVE: Important warning from Rocky's disaster boss

APPROACHING RECORD: The Mackenzie River at Tartrus has almost hit record heights.

The 1991 flood was Rockhampton's third biggest flood, peaking at 9.3m in Rockhampton, just behind the 1954 flood of 9.4m.

Figures weren't recorded at the Tartrus gauge in 1918, Rockhampton biggest ever flood of 10.11m.

UPDATE: 12pm:

THE main peak in the Fitzroy system is now in the Mackenzie River at Tarturs, which has almost hit record levels.

The water will continue to move downstream next week, with the Fitzroy River at Yaamba expected to exceed moderate flood level, 12m, on Monday.

The river is likely to reach major flood level, 15m, overnight Wednesday into Thursday.

In Rockhampton, the Fitzroy River is set to exceed moderate flood level, 12m, during Wednesday and may reach the major flood level of 8.5m during Saturday.

The Morning Bulletin is monitoring river levels in the Mackenzie River at Tarturs and the Fitzroy River at Riverslea.

The Riverslea level is of particular importance, as the Rockhampton peak is generally one third of the peak at Riverslea.
