Waterwatch is a national community water monitoring program funded by the Commonwealth Government’s Natural Heritage Trust. Waterwatch enables communities to become involved in the monitoring and management of waterways in their catchment. The program aims to build community understanding of water quality issues, and to encourage monitoring groups to undertake actions to rectify water quality problems.
The Waterwatch network is made up of individuals, community groups and school groups who undertake a variety of biological and habitat assessments as well as physical and chemical tests to build up a picture of the health of their waterways.
Waterwatch groups across Australia have initiated many positive, community based conservation activities such as fencing areas of riverbanks, removing litter from waterways, eradicating weeds, and reducing the use of pesticides and other pollutants.
Waterwatch Australia was established in 1993 by the Commonwealth Government.
Waterwatch began in response to growing concerns over declining water quality, and as a means for the Commonwealth Government to work with State and Territory governments to encourage community based solutions to environmental problems. Waterwatch contributes significantly to meeting the community involvement aspects of the National Action Plan (NAP) for Salinity and Water Quality.
Objectives of Waterwatch
< >Waterwatch is an important element in the conservation of waterways. These vital systems are threatened by unsustainable levels of water extraction, the destruction of aquatic and riverbank habitat, weed growth, algal blooms and rising levels of salinity, silt and pollutants.
Waterwatch is successfully addressing these issues by efficiently pursuing its objectives and expanding the network. The vision for Waterwatch Australia is healthy waterways. The goal for Waterwatch Australia is to have community groups and individuals active in the protection and management of waterways.
The objectives of Waterwatch are:
Major National Achievements
Waterwatch in the Burdekin Dry Tropics
The “Addressing Waterway Health” Waterwatch Project, funded by the Natural Heritage Trust started in the Burdekin Dry Tropics region in July 2001.
Conservation Volunteers Australia (Townsville) is the manager of the project. Enthusiastic members of their Green Corps and Green Reserve programs have been trained to monitor the health of local waterways.
These teams of water quality and habitat monitors are available to help school and community groups start their Waterwatching activities.
Another important part of the project involves training individuals who will work in partnership with the Australian Centre for Tropical Freshwater Research (ACTFR) to monitor water quality at reference sites.
Reference sites are water bodies that have had minimum human impact. Water quality testing at these sites provides base-line information enabling comparison with the data from the community sites.
In the Dry Tropics, Water Quality Testing monitors Temperature, Dissolved Oxygen, Electrical Conductivity or Salinity, pH, and Turbidity (or clarity). Chemical kits to measure nitrates and phosphates are used to a lesser extent.
In fresh water, Waterbugs or macroinvertebrates are also used as indicators of Water Quality.
Waterways that are highly polluted or degraded support very little life, so the greater the diversity and abundance of small insects, crustaceans and molluscs surveyed in a waterbody, the healthier it is.
A survey of bugs is a simple but effective exercise for groups to determine the health of their local waterway. Waterbugs are always a popular and intriguing study for people of all ages.
Waterwatching can take place in fresh or salty water, surface or groundwater, and still or flowing lagoons or streams.
Waterwatch, using a conceptual model of Catchment-Corridor-Coast, can play a significant role in improving the health and the biodiversity of a catchment and the Great Barrier Reef Lagoon.
Major Local Catchment Issues
Burdekin and Haughton Catchments
These two rivers can each be divided into 3 sections:
The Burdekin has many large sub-catchments. Some grazing occurs on highly dispersible soils. Sheet erosion hot spots are being addressed by maintaining pasture cover and improved infiltration. Water quality is also being improved by fencing stock from streams, but feral pigs are the new issue.
Cane has meant large loss of streamside vegetation and wetlands. Progressive landholders are rehabilitating streambanks and removing extensive and thick carpets of aquatic weeds. Their removal dramatically improves Dissolved Oxygen levels resulting in improved instream habitats and increased fish diversity.
Grazing predominates in the upper catchment with small hobby farms giving way to expanding urban development in this the most populated centre in northern Australia.
Extensive areas of Melaleuca wetlands have been cleared for semi-rural development. Recently developed techniques have minimized the risk posed by Acid Sulphate Soils.
Introduced fish (Tilapia) and instream weed (Cabomba) are potentially large problems for the loss of biodiversity and water quality.
Townsville City Council is at the forefront for developing diverse techniques to improve stormwater quality before it reaches the Great Barrier Reef Lagoon.
Major Local Water Quality Issues
Burdekin and Haughton Catchments
The Burdekin “Built on Liquid Gold” reflects the immense value of groundwater to the community. Main issues include continuing groundwater replenishment for sustainable production and to keep the saltwater wedge away from productive land. However salinity (dryland and irrigation) is starting to impact on parts of each catchment.
Water quality issues indicate the diverse nature of the many sub-catchments; sediments, Total Suspended Solids, turbidity, Total Dissolved Solids, nutrients, and Dissolved Oxygen.
This small catchment has many diverse earth forms which contribute to many water quality and habitat/biodiversity issues. Northern streams are short and run quickly from the coastal ranges of the Wet Tropics. To the south the floodplains are broad and streams slower and with naturally higher salts. Water quality issues in the southern areas include Dissolved Oxygen and pH.
The significant issue of stormwater is being addressed by state of the art engineering and environmental practises. Thus human impacts from this major population centre on the Great Barrier Reef Lagoon, have been significantly reduced.
In both sub-regions the construction of two very large dams has dramatically altered the nature of the hydrology of the floodplain waterways. Streams that once had periods of flow and dryness now have permanent water, significantly altering water quality, instream values and biodiversity, and riparian vegetation.
Major Local Achievements
Waterwatch in the local region has many cooperative roles with a number of community groups and schools.
Waterwatch is working with Landcare and Catchment groups in the Lower Herbert, Ross and Burdekin River catchments. Members of these groups include innovative and environmentally aware canegrowers and the beef industry, who are working to reduce sediment and nutrient runoff.
A number of schools undertake regular monitoring of their local waterway using equipment loaned by Waterwatch. Their data is used for curriculum activities and also is sent to the National Data base
A few community environmental groups are associated with Waterwatch. They include Rita Island Proress Association, Mangrove and Seagrass Watch, Conservation of Sea Turtles, and Louisa Creekwatch and Mundy Creekwatch.
