Wirrigan, the rainmaker – an Aboriginal Dream time story

Once upon a time in the Dream time, the country was having a long drought. The plants and animals were dying and the rivers were drying up.

Without water, no food could grow and the people were starving. The people grumbled to Wirrigan, the rainmaker.

Wirrigan went to the waterhole in the creek each day and poked a stick in it, but still no rain fell.

On the third day, he left his stick in the water hole.

Near the waterhole was a large open shelter called a bough shed. Its roof and sides were made of branches. 

The next day, he asked the people to use bark and material from the termite mounds to make huts raised above the ground. 

He took the people to the waterhole and he jumped in. Then he asked the people to jump in too.

The young men laughed because they did not believe he could make rain. They threw him in the waterhole three times until he was very cold.

Everyone left the creek.

That night when everyone was asleep in the bough shed, Wirrigan and the old people walked around it many times, carrying their belongings.

Soon, a large, black cloud appeared.

Wirrigan woke everyone up and told them to take shelter in the raised bark huts.

The rain began to fall and lasted for several days. When the rain stopped, the land was green again and food had begun to grow.

The people celebrated by holding a corroboree, but Wirrigan was not happy because he knew that many of the people had doubted him.

To demonstrate his power, he took everyone to a very dry plain. He made a huge torrent of rain fall. It filled the whole plain with water.

However, it did not rain anywhere else.

He told the young men to fish in the water, but they still did not believe in his power. How could there be fish in the water when it was just rainwater?

Finally, they threw their nets into the water and pulled out many different kinds of fish.

No-one doubted Wirrigan again. And the great plain filled with water became known as Corcoran Lake.
