Estimated Walyunga Pool Water Level (including history and Toodyay)

The chart above is created on demand (when you load the web page) from the Swan/Avon River Department of Water gauge data at Walyunga (or Great Nth Hwy depending on their status) and scaled based on our personal data recordings of the wooden gauge at Walyunga pool. It usually estimates the level within a few centimeters. This technique evolved from earlier work using an equation fitted to historic data recorded on Robyn Khorshid's great paddlers website.

If the WRC data is below 10.0 metres (e.g. through summer) no graph data is produced or added to the database since this data is meaningless (and the river is way too low for white water anyway!).

This second chart is the same information as stored in a database since May 2005.

Here is a chart for the Toodyay ti-tree gauge at Long Pool (based on the DOW Toodyay gauge):
