Recent SEQ rainfall event

On Friday the 1st of May, south east Queensland had a major rainfall event with 300+ mm occurring over a few hours in some catchments. Minor to major flood levels were hit in many of the systems.

On the following Saturday morning, I did an aerial assessment in a small plane with Seqwater to assess the damage of the event. The assessment included the Mary River, Stanley River, Upper Brisbane River, Mid Brisbane River, Lockyer Creek and North Pine River catchments. We've been working closely with Seqwater to implement restoration works in all of these catchments.

These catchments are crucial for SEQ water supply, however they have some pretty major erosion problems, which impact on water quality. It was amazing to see the sediment plumes entering all the major dams (Somerset, North Pine and Wivenhoe). The assessment highlighted the ongoing importance of improved catchment and river management to help protect our water supplies.

Here are some more photos of the floods, sediment plumes and dams spilling.
