[4] The Darumbal (Tarumbul, Tharoombool) language region includes the city of Rockhampton extending south towards Raglan Creek and north towards the Styx River and inland along the Broad Sound Ranges.

[7] In July 1872, a Rockhampton architect John William Wilson found a large salt water crocodile known as Big Ben dying in Alligator Creek (it had been shot).

In October that year, Wilson displayed Big Ben and some other crocodiles in Rockhampton's Theatre Royal.

[14] On Saturday 16 January 1926, the Yaamba pumping station was officially opened by the Mayor of Rockhampton Theodore William Kingel and Minister of Railways James Larcombe.

The water from the Yaamba pumping station was then piped to a filtration plant at Mount Charlton (in The Caves) before being distributed through the city.

Due to World War I, the need to raise the funds to build the new supply, and ongoing public opinion that a cheaper solution must be possible, construction did not commence until 24 January 1924 when James Larcombe turned the first sod.

[17] After the World War II, it became clear that the continued growth of Rockhampton combined with periods of drought would require more water than what was currently being sourced from Yaamba.
