  Notice 2018-55: Decline in waste water quality, Cape Peron ocean outlet

Cape Peron ocean outlet

Mariners are advised that a recent water quality monitoring survey has shown elevated microbiology in the marine environment off Cape Peron. The elevated levels have been caused by a decline in the quality of treated waste water leaving the Woodman Point Waste water Treatment Plant since mid-February 2018. The drop in quality has resulted from works associated with the current major upgrade project under way at the Plant.

As a precaution, Water Corporation has advised people not to swim, dive, kayak or fish within a one kilometre radius of the outlet of the Cape Peron Ocean Outlet until further notice. This outlet is four kilometres off shore from Cape Peron, in a channel 20 metres deep. The fishing restriction includes shell-fishing, crabbing and cray-fishing.

  • Chart Reference: Department of Transport Chart WA913 - Cape Peron to Dawesville.

Further monitoring is under way and the results will assist Water Corporation to work with its regulators to determine when this precautionary advice can be lifted.

Water Corporation expects the quality of waste water leaving the plant to significantly improve over the next month as the work that affected waste water quality is completed.

Authorised by: Mark Briant Manager, Navigational Safety, Marine Safety Department of Transport.

  • End date: Until further notice

  Notice 2011-98: Commercial fisheries, Mandurah to Geraldton

Various, Metropolitan coastal, Peel

Mariners are advised that commercial fisheries for rock lobster and octopus are established in Western Australian coastal waters, along the coast from Bunbury to the Pilbara and from shore to the 200 metre isobath with areas of high activity between Mandurah and Geraldton, particularly in the region Cervantes to Dongara. Fishing is done using pots or traps sitting on the seabed.

Each fishery contains in excess of 30,000 pots which are marked by floats not less than 200 mm in diameter and coloured, usually fluorescent green. The floats are located on either end of a line of pots or on each individual trap. As the floats are small and unlit, a good lookout is essential when transiting the region. The fishery is active throughout the year with operations conducted by licensed support vessels.

Operators monitor Marine VHF Radio frequencies 74 and 78.

Mariners are advised to navigate with caution when navigating in WA coastal waters to keep well clear of all fishing operations at all times.
