Site: Five Mile Brook Constitution Street

Clearing out rubbish and trimming grass at Five Mile Brook at Constitution Street.

Water Index Rating for Test Sites

Site: Five Mile Brook

Shopping trolleys, bikes, blinds and car engines were some of the items removed.	Clearing out rubbish from Five Mile Brook near Adam Road.

The area alongside the hockey stadium was cleaned out by students.	Litter accumulates along the length of Five Mile Brook, much from drains emptying into the creek.

Conclusion

The main concern with Five Mile Brook is the amount of rubbish finding its way into the water. There are many drains emptying storm water into the creek. This is the source of litter such as plastic bottles and food wrappers. However there is also a large proportion of household refuse which has been discarded into the creek. Hopefully our Habitat signs will inform people that the creek is a valued ecosystem. The City Council has also made a great contribution by cleaning out sections and revegetating banks near Adam Road and Hay Park .

In spite of the litter, our water sampling has indicated the presence of sensitive macro invertebrates, but their numbers aren’t high. Tadpoles and long necked turtles are still seen swimming in the creek. The high number of gambusia remain a concern. Our regular trapping collects many but they are proliferic breeders and can tolerate poor water conditions and higher salinity than the Western Pygmy Perch and Western Minnow.

The aquatic plants are plentiful along the creek and they provide a good habitat for the development of juvenile fish.

We have released Western Pygmy Perch and Western Minnow into Five Mile Brook in 2006 and 2007. Because of its flow and length we do not expect to recapture any in the near future but will continue to release the fish and sample in summer when the water flow slows.
