Williams River Erosion Study

Roads and Maritime has released findings of a study into river erosion that recommends implementing land- and water-based erosion management measures to ensure a successful, long-term outcome for the Williams River.

Have your say

Roads and Maritime is seeking your feedback on the Williams River report. Read a summary, or download a copy of the full report (18.4Mb). To find out how to have your say before 20 November 2016 see What’s happening now?

In early 2015 Transport for New South Wales (TfNSW) released its Regional Boating Plans for NSW. One of the common issues identified during this consultation process was riverbank erosion.

A state-wide framework for riverbank management has been developed to ensure riverbanks are managed consistently and maintained for future users. A scientific assessment of the causes of erosion and potential management options is a key element of this approach.

In response, TfNSW and Hunter Water commissioned the University of New South Wales’ Water Research Laboratory (WRL) to carry out a study that assessed riverbank erosion along 38km of the Williams River, from Clarence Town, to Seaham Weir, and to the Hunter River confluence at Raymond Terrace, supported by Roads and Maritime.

Roads and Maritime has released this technical report, titled 2015 Riverbank Vulnerability Assessment using a Decision Support System: Seaham Weir Pool and Lower Williams River and is now seeking community feedback.

What's in the report?

The WRL report identifies 'a range of factors, including boating activities, poor land management practices and flooding have degraded the condition of the riverbanks along the Williams River study area'.

It provides advice on management options at sites that are highly vulnerable to erosion. In its findings, the WRL report recommends that remedial riverbank work and temporary boating restrictions are implemented to prevent further riverbank erosion.

You can read a summary of the report.

Roads and Maritime will consult with the community and stakeholders, and determine the best course of action to balance the needs of river users and those of the river itself.

What's happening now?

Roads and Maritime is seeking feedback on the report, and would also like to hear your feedback on the following:

  1. What has not been considered by the report?
  2. What type of management options would best complement other local activities and priorities?
  3. Are there any broader regional initiatives or solutions that could be considered?

We invite you to have your say until Sunday 20 November, and put forward any ideas, especially along the lines of the three questions above.

You can provide feedback by sending an email to WilliamsRiverStudy@rms.nsw.gov.au, or post your feedback to Williams River Erosion Study, Roads and Maritime Services, Locked Bag 5100, Camperdown NSW 1450.

What happens next?

Following this period of feedback, Roads and Maritime will consider community feedback and the findings of the study to develop a draft Erosion Management Plan, which would propose appropriate land- and water-based erosion management measures that would help protect the river.

Roads and Maritime will then consult with the community on the draft Plan before implementing any solutions. We will continue to keep the community informed as the project progresses.

If you have any queries, please email WilliamsRiverStudy@rms.nsw.gov.au or call 1800 875 116.
