Council commercial portfolio manager Mike Hibbert said work is planned to start in mid to late February, but is heavily dependent on the weather.
A total area of 6.1ha will be harvested, with an expected yield of 3900 tonnes of wood.
The area will then be replanted in native trees that comply with the New Zealand Emissions Trading Scheme. The logging will be carried out by a bulldozer, with a series of tracks created in the hillside to allow the trees to be removed.
The 700m boundary fence will be removed and then replaced at the end of the harvest.
A temporary access road and a loading platform for logging equipment and trucks will be constructed close to the dam entrance gate. A second loading platform will be constructed close to the carparking area at the top of the dam.
These will be removed and the land regrassed once the work is complete.
Mr Hibbert said the council is working closely with the contractors and water services team to ensure there are no risks to the water quality.
A post-harvest clean-up will take place to remove any leftover debris from the popular site.
