Dumbleyung is a small wheatbelt town located 275 km south east of Perth. No one knows exactly how the town received its name, but it is likely that it is a corruption of the local Aboriginal word 'dambeling' which probably meant 'large stretch of water'. An alternative theory argues that it may well be derived from 'dumbung' which either meant a native pear tree or an Aboriginal game played with bent sticks and a hard piece of fruit.

Although in many ways Dumbleyung is a typical wheatbelt town there is one event in its history which makes it uniquely important and separates it from the dozens of other towns in the area. On New Years Eve 1964, after a particularly wet winter had seen the lake fill to overflowing, Donald Campbell set the world water speed record when he piloted his boat, Bluebird K7 across the lake at the remarkable speed of 444.66 km/h (276.3 mph). This was to be his finest achievement, he had done the double of water and land speed records in one calendar year, a feat that will probably never be seen again. A memorial to Donald Campbell's achievements is located on Pussy Cat Hill on the lake shoreline. Offering excellent views over the lake, it is clearly signposted 'Scenic Drive - Lake Dumbleyung' on the road from Wagin to Dumbleyung.

Lake Dumbleyung, undoubtedly the area's great attraction, is the largest natural body of inland water in West Australia. It is approximately 13 km long by 6.5 km wide with a catchment area which extends approximately 64 km north towards Kulin, 64 km south towards Narrangerup and 55 km east to Tarin Rock. In the years when it overflows the water takes a course through the Wagin Lakes into the Beaufort River, thence the Blackwood and into the sea at Augusta.

The first recorded sighting of the lake was in 1843 when two explorers Henry Landor and Henry Maxwell Lefroy travelled through the area looking for pastoral lands and a large body of water which had been mentioned by the local Aborigines.

Landor and Lefroy described Lake Dumbleyung in their journal entry for 17 January 1843. 'After riding 10 miles, we came in sight of Dambeling, the largest of the lakes - 13 miles by 7 or 8. It is like the others, shallow with many low islands in varied and beautiful form. On the northern and eastern shores, there is a good grazing country down to the lake, ending in precipitous banks and extending over the hills 2 or 3 miles distant from the lake. The water is salt and the shore long, flat and muddy, on which we saw the impressions of two stray horses and a foal...'

The first grazing leases around Lake Dumbleyung were granted in 1875 to George Kersley who overlanded sheep from Beverley and took up a lease of 20 000 acres which included half of the lake. Early accounts describe the lake as having grass covered banks and the saltbush provided valuable grazing for Kerseley's stock.

The pastoralists were followed by the sandalwood cutters who came through the area searching for the aromatic timber. It was also common for farmers to cut the timber as it was a ready source of income during hard times or periods of inactivity.

Other early accounts describe a road across the lake used by Katanning settlers to cart produce to the goldfields in the 1890s. This was the opportunity for local farmers to make a fortune as quickly as the miners. They would load their wagons with flour, sugar, oatmeal, jam and baking flour and when they got to the goldfields actually auction their produce.

While the lake is used for aquatic recreation today, in the early 1900s there were race tracks on it and it was used for picnics. During the 1920s and 1930s, although the lake did not fill to overflowing, there were years when it had enough water for swimming and boating. A record wet year in 1946 saw the lake fill completely.

In recent times the lake has suffered greatly from the salination which has affected the whole of the wheatbelt. The shorelines, which the early settlers described as being so rich and fertile, are now characterised by forests of dead trees standing like forlorn skeletons. Most of the lake is part of a water bird conservation area.

The town of Dumbleyung seems to run a rather poor second to the lake but it is not without its charm. It came into existence just prior to World War I. The township was proclaimed in 1906 and the railway arrived a year later. From 1907-1912 Dumbleyung was the railway terminus which meant that it became an important meeting place. The Dumbleyung Hotel was built in 1913 and by 1915 Dumbleyung was the major rural service town in the region.
