Darawakh/Frogalla Wetland Management Plan
Last modified: June 2, 2009 - 2:40 PM
This project aims to reduce acid sulfate discharge into the Wallamba River.
The Darawakh/Frogalla wetland acid sulfate soil problem was identified in 1998/1999 although users of the Wallamba River had noticed the effects of acid discharge (red-spot disease in fish, oyster mortality) for many years. Council conducted water quality monitoring and confirmed the severity of the acid sulfate generation in this landscape, which results in significant acid flows to the lower Wallamba River. This discharge has negatively affected both commercial and recreational fishing and oyster production in the lower Wallamba River.
Upon identifying the scale of the problem, Council commissioned the preparation of a Darawakh/Frogalla Wetland Management Plan to identify the range of management solutions to this severe water quality problem. In 2004, Council commenced the implementation of this Strategy.
The project is now nearing completion. Over 80% of the drains have been filled or decomissioned and 80% of properties acquired.
