Catchment Area
Many of the tributaries of the Helena River are unnamed due to their seasonality and size. However on the northern side of the catchment Nyaania Creek and on the southern side Piesse Brook are significant in their moving through built up areas which makes them susceptible to urban environment issues.
Upper Helena catchment (i.e. above Mundaring Weir) has on the north side of Lake C.Y. O'Connor (formerly the Helena River Reservoir) a range of named creeks that occur in State Forest no 71 and 13:
- Manns Gully
- Chinaman Gully
- Jones Gully
- Michael Gully
- Chauncy Gully
- Middle Brook
- Helena Brook
- Hancock Brook
- Emu Brook
- Warin Brook

Famous quotes containing the word area:
“During the Civil War the area became a refuge for service- dodging Texans, and gangs of bushwhackers, as they were called, hid in its fastnesses. Conscript details of the Confederate Army hunted the fugitives and occasional skirmishes resulted.”
—Administration in the State of Texa, U.S. public relief program (1935-1943)
