Cumulative sediment load, daily maximum flow and daily total rainfall for the 2022/23 monitoring season. Sediment load is predicted using a turbidity vs discrete suspended sediment concentration model that is updated each year, see Morar & Alberto (2018) for more information. Note: when there are gaps in the sediment load predictions, the resulting cumulative and annual sediment load totals may be underreported.

The dashed flow event lines represent the flow level at which we would expect n years before another event that size (e.g. 1-yr suggests a flow event that size occurs on average once every year). Hover over chart series to see specific values.

Toggle between tabs below to see sediment loads and yields of key events and annual totals. Click on table headers to sort the data by that column – holding the shift key allows sorting over multiple columns. Hovering over events will highlight that period on the chart above.

2022/23 event loads

Long-term annual loads

1: Annual sediment loads published in reports prior to 2022/23 will vary from what is published for the current report due to updates in the load calculation. Annual loads published in the current report are the most up-to-date.
