Creek monitored in wake of Violet Town-Boho fire

Sediment levels in Honeysuckle Creek have increased as a result of last week's heavy rainfall in the fire-affected Violet Town-Boho area.

Sediment levels in Honeysuckle Creek have increased as a result of last week's heavy rainfall in the fire-affected Violet Town-Boho area.

Goulburn Broken Catchment Management Authority (CMA) Strategic River Health Co-ordinator Simon Casanelia said the CMA had contracted Goulburn Valley Waterwatch staff to monitor turbidity in Honeysuckle Creek after a large bushfire burnt almost 1300ha of land late January.

"Many of the creeks in this area are ephemeral and hadn't flowed for a while," Mr Casanelia said. "However, after the recent heavy rain they have started flowing again and not surprisingly we have seen increased turbidity levels in the creek caused by run-off from fire-affected land."

High turbidity levels can adversely affect waterways by increasing water temperature, reducing dissolved oxygen and restricting aquatic plant growth. In addition, when the suspended sediments settle out they can fill in holes and the spaces between rocks and logs on the bed of the waterway decreasing the type and amount of habitat for fish and other aquatic animals.

Goulburn Broken CMA has been working with the CFA, local government and the Department of Primary Industries to help with the fire recovery process. Planned works include the rehabilitation of tracks, control lines and stream crossings as well as measures to address pasture loss and erosion.

"We know the recovery process will take a while and appreciate the efforts of landholders and agency staff," Mr Casanelia said. "This ongoing monitoring of the waterways will help inform us about the effectiveness and progress of those rehabilitation efforts."
