Preventing fish kills in local waterways

FREE prawns!

Now that we have your attention, those delicious, fresh locally caught prawns are only on offer to those who attend Richmond River County Council's groundwater control field day at Kookami Swamp near Coraki on January 24.

It aims to showcase work completed last year to raise the groundwater levels of the swamp, reducing the risk of blackwater events, poor water quality, and subsequent fish kills.

The project was funded by the Northern Rivers Catchment Management Authority.

RRCC will host the field day at Kookami Swamp in conjunction with WetlandCare Australia and the Department of Primary Industries.

Floodplain project officer, Garry Owers, said the swamp was drained in the 1950s and became a source of acid water and blackwater in waterways.

"Raising groundwater levels reduce the oxidisation of acid sulphate soils while promoting the establishment of native wetland plants and pasture grasses," he said.

"For example, native water couch is less likely to die when flooded thus reducing the risk of blackwater production and the resultant poor water quality and fish kills.

"As an acknowledgement of the project's improvement to fishing, we will supply locally caught prawns on the day for all those attending."

To register and for more information, times and directions to the site please call Mr Owers on 6621 8314 or email garry.owers@rrcc.nsw.gov.au
