Byron Echo, Letters, 5 April 2023:
It seems our elected councillors are at odds with non-elected Council staff over the future of Mullum’s water supply.
My concern is that there is no consideration in the current arrangements for environmental flow in the Wilsons Creek/River below Lavertys Gap weir. This obviously didn’t seem like a big issue when the agreement was drawn up several decades ago and the population of the area was a fraction of what it is today.
However, our population is growing and every new house has flush toilets, showers and gardens to water. Might these houses be required to at least have water tanks as every roof is a perfect water catchment?
In the last drought (2019–20) the area downstream of the weir was almost stagnant. This is a vital habitat for platypus and many other native species. Local residents also rely on the creek to water food gardens.
It is crucial that we consider the long-term health of this important waterway and the survival of both native and human inhabitants.
We need to act now for the future and put in place a requirement for realistic environmental flow.
Please speak up for the river by contacting Council: council@byron.nsw.gov.au

The weir at Laverty's Gap supplies water to Mullumbimby. It is a Heritage-listed ageing structure in need of repair, which appears to block fish passage in that section of the Wilsons River and operates under a licence that does not require release of environmental flows to water the downstream environment.
There is community concern that weir capacity only meets current population demand as the weir water supply currently services est. 1,890 residential and non-residential properties and, will not be able to meet need in future droughts given access to emergency water supply is limited to only part of the town.
Water restrictions were imposed in Mullumbimby during the droughts of 2002/03, 2006/07 and 2019/20 and, there is community concern about the degree to which climate change will exacerbate future droughts.
