Inland waterways

Major flooding of the Murrumbidgee River at Narrandera has led to the evacuation of residents in 14 households south of town. Warnings for major flooding are still in place. Narrandera Shire Council Deputy General Manager Infrastructure Shane Wilson said ... the volume of water flowing through the river in a 24-hour period was 130,000 Ml megalitres which equated to 130,000 Olympic swimming pools as against the normal flow rate of 40 megalitres. SES volunteers are keeping a close watch on water levels and checking on residents in low lying areas.

Two community meetings were held in Allora on Monday afternoon to discuss the topic, both involving concerned locals who have properties impacted by floodwaters and representatives of Southern Downs Regional Council (SDRC) ... Many residents believe multiple floods earlier this year along Dalrymple Creek were made worse by the levee bank, particularly around the corner of Raff and Jubb streets.

Work has begun to improve the health of Kanamaluka/Tamar estuary by reducing the frequency and volume of overflow events. As part of the Tamar Estuary River Health Action Plan (TERHAP), a new underground diversion chamber will be sunk deep into the ground at the Margaret Street pump station.

A rescue and relocation operation is currently underway by NSW DPI Fisheries to save Murray Crayfish impacted by poor water quality following flooding along the Murray River. The rescued crayfish will be transported to Narrandera Fisheries Centre for safekeeping until conditions improve and they can be returned to the river safely.

Kirstin Nicholson. Mick Farrant’s dairy farm is on Flannery’s Road, McMillans and two thirds of his 1,100-acre property is underwater. Excess water from Pyramid and Bullock Creeks has inundated the farm. “It’s a big job moving cattle, it’s just a massive undertaking to shift a whole herd and get set up for them somewhere else. You don’t do that in five minutes,” he said.

It’s been over 10 years since a 5-year moratorium was placed on Murray crayfishing by NSW authorities for our stretch of the Murray River. Sadly, now it seems that Murray cray populations are at risk, not from fishing, but from poor water quality. Dissolved oxygen has fallen to 0.2 in the Murray at Barham and thousands of Murray cray have walked to the edges of the river from Echuca through to Swan Hill.

The river continues to rise at Wilcannia and is now running at just over 10 metres with a flow of 30,043 ML/day. Lake Woytchugga is continuing to fill and the Talyawalka is flowing at 6.7 metres. The river is running at 101,727 ML/day at Bourke and over 135,214 ML/day at Walgett, indicating that there is a lot more to come.

Cook Shire Council is pleased to announce that with repairs to the approach ramps of the Marton Swing Bridge coming to completion, the bridge is scheduled to reopen in coming days – ahead of the approaching wet season.

In our immediate area, we are lucky: the floods have been and gone while others across the State and beyond are still living with the uncertainty and dangers of rising river levels. For our region, it’s on to the recovery stage.  The Times visited the Baringhup Caravan Park last weekend to view the damage following a massive release of water from Cairn Curran reservoir.

Somebody better tell mother nature to get with the program as Koondrook-Barham’s peak was exceeded seven days early. The expected peak for Koondrook-Barham remains unchanged on official channels at an expected 6.2m. Mother nature had other ideas with a rainfall event on Monday, October 24 pushing the river to an eye watering 6.210m just one centimetre short of the highest recorded on NSW Water, the 1917 flood reaching 6.223m.

More than three times the average October rainfall has already fallen in Narrandera this month with more than 100mm drenching Narrandera in the first three weeks of October. The deluge has caused chaos with many roads being closed.

Kirstin Nicholson. Pat and Michelle Quinn’s dairy farm at Mincha West is under real threat of flooding. The 700 head dairy property sits about 3km from Flannery’s flume, and the water coming out of Kow Swamp backs up and flows over the top of the property ... In 2011, the farm was completely inundated – and Pat is predicting this flood will be the same.

Kendall Jennings. Amidst the sound of helicopters, drones and light aircraft, the community of Kerang gathered to do whatever was needed to protect vital infrastructure as the Loddon River, Nine Mile Creek and Pyramid Creek water levels rose. Earthmoving machinery was used, along with sandbags to contain floodwater away from major roads, however, some efforts did not survive the floodwater onslaught.

When viewed together the 30 major dams across the Murray-Darling Basin are currently at 101% capacity and  hold an unprecedented volume of water in storage ... At the Authority’s invitation, the  South Australian River Murray Commissioner, Mr Richard Beasley SC, attended the meeting. He provided an update on his appointment to advocate for the health of the River Murray, Lower Lakes and Coorong.

The Murray–Darling Basin continues to experience widespread flooding in some areas, prompting an increased risk of water quality issues like low-oxygen blackwater as temperatures increase. Governments and water authorities are working together to monitor the unfolding conditions which may see low-oxygen blackwater and blue-green algae emerge that can lead to fish deaths and increased water treatment.

For rural and regional communities, especially those crying out for dams for flood and drought mitigation for decades, Budget Paper Number 2 from the Commonwealth 2022-2023 Budget makes depressing reading.

As at 26 October, the flooding continues at Undera and, with no authority prepared to take responsibility for the levees, it's left to the community - somehow, sometime - to repair the multiple levee breaks.

New inundation maps and a comprehensive list of frequently asked questions have been created as part of dedicated webpage on the highest River Murray flows in almost 50 years. Flood awareness, infrastructure and projected flow maps allow residents to look at potential inundation and check if their property is likely to be affected.

Emergency Management Victoria, the lead agency in Victoria during an emergency event, made the decision on Monday, 17 October that a levee needed to be constructed in Echuca to protect as much of the township as possible. Based on the flood modelling available in the Incident Control Centre in Bendigo, Emergency Management Victoria had 48 hours to put the levee in place

The entire Central Victorian region has been smashed by catastrophic floods, which appear to be more serious and more widespread than the 2010 and 2011 floods. With many regions experiencing record-breaking rains over catchments that were already sodden, the end result has been devastating. Gutters have turned into creeks, creeks into raging rivers and rivers into churning brown oceans ... Geoff Palmer took this photo of the spillway at Cairn Curran last Thursday.
