The 1937 flood

It is eighty years since the Koo-Wee-Rup Swamp experienced the second largest flood in its history. The largest flood took place in the first week of December 1934. The 1937 flood hit the area on October 18 and water was 60cm deep in Rossiter Road and Station Street in Koo Wee Rup. The flood peaked at 20,000 cusecs (50,000 megalitres) about half the 1934 flood volume. There had also been a smaller flood of around 10,000 cusecs in April 1935.

The 1937 flood was caused by an extraordinary amount of rain over the proceeding few days. The Argus of October 20 1937 had a map showing the rainfall totals of the five days from the 14th to the 18th of October and Dandenong had 532 points (just over 5 inches or 125 ml) and Gembrook had 977 points – close to 10 inches. The Pakenham Gazette reported that Pakenham had over 4 inches at the same time and Pakenham Upper 7.5 inches.  As you would expect, with that amount of rain, parts of Melbourne including the Yarra River and the Patterson River also flooded.

The Koo-Wee-Rup Sun of October 21 1937 reported that the experience of previous floods had taught Swamp settlers the lesson of removing stock and what property that could be shifted to higher levels and this precaution, as far as possible, was taken. Therefore although the body of water was almost as great as the 1934 flood, damage to the above was in no way as large. Crops however suffered in many cases owing to the waters being diverted since then, there were many cases in which settlers fared worse by this deluge. The Koo Wee Rup Sun estimated the damage at £50,000.

The townsfolk placed the blame for the water in Koo Wee Rup squarely on the closure of the openings in the railway embankment which caused the water to be bottled up in the town. They were made even angrier by the fact that this was seen to be the cause of the town being flooded in the 1934 and 1935 floods and there had been no action to rectify the problem. The Koo Wee Rup Defence Corporation was established after the 1937 flood, at a representative meeting of trades people, residents and farmers of the township and district... Nothing but bitterness was expressed at the continued apathy of Government bodies in ignoring all the past representations and in failing to at least take measures to ameliorate the consequences of the disastrous flooding.  The Koo Wee Rup Sun reported that in 1934, the Premier, Mr Dunstan, had promised to go into the question of co-ordination of the Railways and the State Rivers & Water Supply Commission but up to the present had sat idle.




Letter to the Editor of The Argus October 25, 1937

There was a lot of publicity about the effect of the flood in the Koo Wee Rup township but surrounding areas also suffered as testified in this letter to the editor of The Argus on October 25, 1937 signed ‘Also a mug’ from Cora Lynn.  
 It is a cause of annoyance to residents of Cora Lynn and adjoining districts to read in the newspapers, and to hear over the air, the plight of the people of Koo-wee-rup. We are sorry for them, but they have the railway to remove them from the danger zone. They have many more hours of warning than we, with greater facilities for getting away. The water that floods Koo-wee-rup has previously surged over our lands and homes. Long before the flood reaches us in Cora Lynn all means of exodus have been cut off by the flooding of such towns a Vervale, Iona, Tynong, and Garfield for the most part. Cora Lynn is in a very decided depression, and, in my opinion, suffers more than most of the unhappy districts during the awful floods which visit us with monotonous regularity.

The Age of October 19, 1937 had this report about the effect of the floods in the local area.
The rain continued almost continuously until to-day, when about 4 inches had been registered. At Picnic Point the Tarago River overflowed several properties. At Longwarry it flooded the butter factory to a depth of 4 feet, causing considerable damage to the machinery. Stores had to be removed to the mechanics' hall for safety. North of Garfield, Cannibal Creek over flowed its banks by 5 feet, and properties in this area were flooded. The Ararat Creek between Tynong and Nar Nar Goon became flooded, and there was 3 feet of water on Princes Highway. The
Longwarry-Nar Nar Goon road, which runs parallel to the railway line, was submerged for more than half a mile. The railway embankment and line was washed out for a distance of 26 chains, and the railway service was disorganised. Buses had to run from Nar Nar Goon to Bunyip.
 The main canal fed by Bunyip and Tarago rivers first overflowed its banks at Cora Lynn, but later it overflowed near Long-bridge, between Longwarry and Bunyip. The water is now over the Princes Highway and the the Longwarry-Nar Nar Goon road. Many residents have been compelled to go to Bunyip, as their homes have been flooded. Stock, sheep and pigs, wherever possible, have been removed to higher ground.
At Cora Lynn there is 5 feet of water in the Drouin Co-operative Cheese Factory, and at Keast Hall the water is flowing through the windows. At the railway bridge between Bunyip and Longwarry the river overflowed its banks. The Bunyip show ground is submerged to a depth of 2 to 3 feet, and water is flowing copiously across the old racecourse. The golf links is a lake of water. Many residents have water running through their homes and women and children have been removed to places of safety. It is feared that if the rain continues throughout the night the record flood of 1934 will be eclipsed.
  
A report in The Age of October 20 said that the ballast that had been washed away from the railway line between Nar Nar Goon and Tynong was replaced the day before and by 10.00am the line was ready for light traffic. The Argus of October 20 reported on the telephone lines The exchange at Iona, near Bunyip, went out of order when flood waters reached the cables. The exchange was in touch with Melbourne, but could not give connection to subscribers. Men were working on the fault last night, and expected to have the lines clear by this morning. All other country exchanges carried on services.

As we saw before there was widespread unhappiness and anger after the 1934 flood and, as a result, the State Rivers and Water Supply Commission (SRWSC) worked on new drainage plans for the Swamp and these plans became known as the Lupson Report after the complier, E.J Lupson, an Engineer. A Royal Commission was also established in 1936. Its role was to investigate the operation of the SRWSC. The Royal Commission report was critical of the SRWSC’s operation in the Koo-Wee-Rup Flood Protection District in a number of areas and it ordered that new plans for drainage improvements needed to be established and presented to an independent authority. Mr E. G Richie was appointed as the independent authority. The Richie Report essentially considered that the Lupson Report was “sound and well considered” and should be implemented. Work had just begun on these recommendations when the 1937 flood hit the area

The main recommendation of the Lupson / Ritchie report was the construction of the Yallock outfall drain from Cora Lynn, cutting across to Bayles and then essentially following the line of the existing Yallock Creek to Western Port Bay. The aim was to take any flood water directly to the sea so the Main Drain could cope with the remaining water. The Yallock outfall drain was started in 1939 but the works were put on hold during World War Two and not completed until 1956-57. The Yallock outfall drain had been originally designed using the existing farm land as a spillway i.e. the Main Drain would overflow onto existing farmland and then find its own way to the Yallock outfall drain. Local farmers were unhappy at this, as the total designated spillway area was 275 acres. They suggested a spillway or ford be constructed at Cora Lynn so the flood water would divert to the outfall drain over the spillway. The spillway was finally constructed in 1962.
