After the rainfall events of the past couple of weeks, there are a few ‘frequently asked questions’ about erosion and waterway health.

The NSW DPI have a flood impact survey out and we would encourage everyone to submit a survey – this helps with estimating the cost to producers and what programs and assistance there may be.

There has been a disaster declaration for Greater Hume Council area from 14th September 2022 onwards and there are a range of assistance measures available. We recommend visiting   https://www.nsw.gov.au/disaster-recovery/natural-disaster-declarations  and https://www.raa.nsw.gov.au/ for up to date information.

The Woomargama, Mountain Creek and Ten Mile Creek systems were at the epicentre of the severe rainfall event here on the weekend (160mm reported). The resulting bank erosion and sedimentation in the waterways is causing headaches for some with impact on infrastructure.

Before you get the machines in, be aware of your obligations for permits – repair of existing crossing etc may be exempt but we encourage people to check out the following to cover yourselves

The LLS have some good factsheets available as part of their riparian restoration program

How should I undertake erosion works after a flood?

Managing erosion before and after floods

What can I do to address riverbank erosion on my property?

Early intervention in erosion in paddocks and smaller waterways is a worthwhile investment now – the high rainfall may have exacerbated small headcuts, stock tracking and track erosion.

The Rivers of Carbon project has some great resources on treating small headcuts (“below your knee”) yourself and maintaining tracks and roads to prevent erosion problems

Floods are a natural part of the cycle for our waterways, so most of our aquatic species are adapted to coping. The environment will recover – if anyone has any concerns feel free to contact us and we can see if we can help.

Through the Refreshing the Upper Billabong project we are undertaking waterway management planning and hearing about the experiences of the flooding and what management issues are being faced will help inform our programs. Contact Kylie on 0418198522

Refreshing the Upper Billabong is part of the Refreshing Rivers project, a collaboration between government, industry, research, and community organisations, led by Murray Local Land Services. This project has been assisted by the New South Wales Government through its Environmental Trust
