Spatial Watershed Assessment and Management Model

SWAMM is an open data platform where citizens, waterway managers, farmers and government
work together to reduce pollution loads to our waterways.

SWAMM allows you to understand where the pollution is coming from, and how best to mitigate it.

It encourages unified, efficient and fair management solutions.


Data Driven

Our geospatial platform encourages consistent, evidence based decision making.



Being online allows genuine feedback and iterative assessment in the face of constant change.


Future Proof

These watershed plans build on prior efforts, but importantly preserve work so future users can access and leverage.

Step 1
Understand the problem.

Explore SWAMM's pollutant mapping across the watershed.

Nitrogen, phosphorous and sediment pollution is generated at different rates, depending on landuse, soil type, rainfall patterns and topography across the watershed.

This pollutant generation was mapped as part of the Lake Springfield Watershed Management Plan 2016, and is now available through SWAMM.

It's important because excessive sedimentation is reducing the lake's storage capacity, making the Springfield’s water and power supply more vulnerable to drought and climate variability.

Step 2
What solutions are planned? Let's see.

You can explore the currently proposed or built solutions within the watershed.

With this knowledge, you can coordinate and collaborate so solutions complement each other effectively.

SWAMM's user and organisation management tools allow you to securely share your data when you are ready.

Step 3
How effective will each one be? Is this the best way to achieve results?

Select a type of Best Management Practice, draw your proposed treatment areas, and SWAMM will calculate the potential pollutant reductions for you right away.

Once you're happy with the BMP, you can share the details, or print a report to support a grant funding application.

A well sited and well designed BMP can improve crop yields whilst reducing soil loss and pollutant runoff.

Step 4
Nice. But let's work together, right?

SWAMM provides a dashboard that aggregates all the activity within the watershed.

It then tracks our collaborative progress towards the water quality goals, including the Total Maximum Daily Load set under the Clean Water Act.

Working together means that every contribution is recognised and valued, lessons can be shared and everyone comes out better than before.
