It was originally known as the Smiths Mill Brook on maps between 1902 and 1920. In the 1920's it became known as Nyaania Brook, and in 1945 it officially took the current name.

Its importance stems from the fact that it flows through private land for most of its length, linked to issues that affect watercourses in the Darling Scarp region:
  • usages of herbicides and other contaminants that can become waterborne
  • excess nutrients from fertilisers used in domestic gardens
  • inappropriate exotic weeds that flourish in difficult to access locations.


It has significant areas of reserves either adjacent, or within 100 metres either side of its main creek bed. It runs in a number of places along what was rail reserve of the Eastern Railway - which is now the southern part of the Railway Reserve Heritage Trail

 and near Devil's Terror.

Devil's Terror Springs

Historically it achieved its significance in the construction of the Eastern Railway where a surveyed route of the railway encountered difficulties with the creek and creek bed. As a cutting was being constructed (near the bottom of Dalry Rd) clay was struck followed by an underground stream which flooded the clay and turned it into a bottomless bog.
The locality earned the name in the Perth

 newspapers of the 1880's as The Devil's Terror and they cite the example of workers sinking in mud.

That section of the raiway had to be resurveyed and was shifted 100 meters south along the bed of Nyaania creek. The creek above Glen Forrest was diverted into Chittawarra Brook while a dam was thrown across the creek just to the west of Glen Forrest to hold back the water while a man made channel was built to replace the original creek bed. On completion of the channel the dam wall was breached and Nyaania Creek was allowed to run into the new channel.
As a result of this construction the creek bed now runs along the top of the 3 to 5 meter deep cutting. In winter the water can be heard rushing just above ones head as they walk through the cutting.

For the duration of the Eastern Railway route usage (1880's to 1953) the Nyaania Creek/Eastern Railway/Devil's Terror location point of coincidence has had springs under or next to the railway line. The sleepers and rails were removed in the mid 1960's, and ever since they have subsisted even when the Nyaania Creek is dry in the middle of a drought.
