Streamwatch in Greater Sydney – A Citizen Science Water Quality Monitoring Program

Streamwatch is a crucial water quality monitoring initiative across Greater Sydney that harnesses volunteer efforts to gather vital data on the health of our waterways. Read on to learn how this citizen science program works and the immense value it provides.

Streamwatch allows everyday citizens to contribute to scientific understanding of water systems through consistent tracking of key indicators. The program provides equipment, training, coordination and a central database for community members to easily collect and share reliable waterway readings. This data aids conservation efforts and informs policies for improved environmental stewardship.

What is Streamwatch?

Streamwatch is a citizen science water quality monitoring program covering Greater Sydney. Initiated by Sydney Water and the Sydney Catchment Authority in 1998, it led to Waterwatch Australia which now has groups nationally.

Volunteers regularly test chemical and biological parameters at assigned sites along their local rivers, creeks and streams. The Streamwatch program provides equipment and teaches sampling methods to ensure accurate, quality-assured data. Groups then upload their data sets to the online database maintained by the Australian Museum through the NSW government’s portal for sharing environmental data.

Why is Water Quality Monitoring Important?

Routine monitoring by Streamwatch groups serves several vital purposes:

  • Track conditions over time to identify pollution events, trends and gradual change.
  • Build an extensive water quality dataset across diverse waterways and conditions.
  • Raise awareness of local stream health and catchment influences among participants.
  • Inform management decisions by authorities regarding watershed protection.
  • Engage the community in stewardship and conservation efforts to protect water ecosystems.
  • Provide baseline data against which to measure the impacts of policies, restoration projects, and climate change.
  • Seed passion for science and the environment through participation.

What Does Streamwatch Monitor?

Volunteers are trained to measure a standard set of water quality parameters using provided kits:

  • Dissolved Oxygen – Levels indicate stream metabolism and suitability for aquatic life.
  • Turbidity – Cloudiness due to sediment affects habitat and water treatment.
  • Phosphate – Excess nutrient from fertilizer and sewage causes algal blooms.
  • pH – Range indicates mineral levels and pollution influences.
  • Salinity – Saltiness from natural or urban runoff.
  • Temperature – Affects oxygen solubility, ecosystem health, and water use.

Sites may also monitor stream flow, aquatic macroinvertebrates, and riparian vegetation as indicators.

Who Can Join Streamwatch?

Many participants are members of environmental groups who “adopt” a local site. But any individual, family, school, or community group can join Streamwatch. The key requirements are:

  • Commitment to monitor your adopted site consistently. This provides the most useful long term dataset.
  • Attend training sessions to properly collect samples and use test kits.
  • Ability to accurately enter results into the online portal after monitoring.
  • Interest in learning more about water science and environmental stewardship.
  • Desire to improve ecosystem health through community science.

How Does the Program Work?

The typical Streamwatch process:

  1. Groups select a local waterway sampling site, or adopt an existing one. Consider ease of access and safety.
  2. Volunteers undergo training together to standardize procedures. Includes site establish, water sampling, measuring with test kits, recording data, and equipment maintenance.
  3. Groups visit sites monthly or quarterly depending on parameters. They record observations and carefully collect samples.
  4. Participants enter findings into the online NSW Water Quality Portal after each monitoring date.
  5. Data is quality assured then integrated into the public database. Available for research and app development.
  6. The Australian Museum provides ongoing coordination, training updates, and equipment replacement as needed.

What are the Outcomes?

Over 20 years, Streamwatch volunteers in Greater Sydney have contributed enormous amounts of reliable water quality data through their admirable commitment. The program has achieved significant outcomes:

  • Over 140 active monitoring sites across the Greater Sydney region. Each contributing continuous datasets.
  • Early detection of pollution incidents, leading to identification and elimination of contaminant sources.
  • Informed policy changes and investments to improve stormwater management, waterway buffers, and environmental flows.
  • Protected sensitive aquatic ecosystems through evidence-based decision making around development.
  • Generated research publications using the unprecedented open access water quality data.
  • Provided infrastructure for other citizen monitoring groups to emerge across Greater Sydney.
  • Inspired and educated thousands of students and members of the community about water science through participation.

How Can You Get Involved?

Joining Streamwatch is easy and flexible. You can participate as an individual or existing group. The steps are:

  1. Attend an info and training session to learn techniques (held regularly around Sydney).
  2. Adopt a site in your area and establish an observation schedule.
  3. Collect data on waterway parameters using provided kits.
  4. Enter results into the online portal after each monitoring date.
  5. Engage your community, from schools to bushcare groups, in the program.

Head to the Australian Museum’s Water Monitoring Programs page learn more and sign up as a volunteer monitor. Consistent, quality data relies on ongoing community commitment. By participating in Streamwatch, you directly contribute to understanding and improving the health of Greater Sydney’s rivers and streams.
