Recreational Releases and Flushing Flows
Genesis Energy's resource consents for the Tongariro Power Scheme require recreational flow releases from Rangipo Dam, Poutu Intake and Whakapapa Intake, as well as flushing flow releases from Moawhango Dam.
Assess the conditions for yourself before entering the river, and please ensure anyone using the river is aware of these flow changes.
Stop the spread of freshwater pests!
All equipment that has come from any other fresh waterway (regardless of island) must be decontaminated using approved methods (see CheckCleanDry) before entering the river.
Please do not rely on the ‘dry' method alone as the inside of kayaks take a very long time to dry out!
Cleaning solution is available at the entry and exit points during recreational releases.
Moawhango Dam flushing flow releases
Flows of 26 cubic metres per second for up to 9 hours are released from Moawhango Dam as required by Genesis Energy's resource consents for the Tongariro Power Scheme. The purpose of the flows is to improve the ecology of the river. As the Moawhango River flows into the Rangitikei River, the flushing flows result in an increased flow in both rivers. Consequently high flows will be experienced on both these rivers on the following dates:
- Wednesday 16 December, 2015
- Wednesday 27 January, 2016
- Wednesday 17 February, 2016
- Wednesday 16 March, 2016
- Wednesday 13 April, 2016
Rangipo Dam recreational releases (Access 13 and 14)
Flows of 30 cubic metres per second for 8 hours will be released from Rangipo Dam between 8am and 4pm on the following dates:
- Saturday 13 February, 2016
- Sunday 17 April, 2016
- Sunday 18 September, 2016
Tongariro River below Poutu Intake recreational releases (Access 10)
Flows of 30 cubic metres per second for 6 hours will be released from Poutu Intake into the Tongariro River between 9am and 3pm on the following dates:
- Saturday 16 April, 2016
- Saturday 17 September, 2016
Whakapapa River below Whakapapa Intake recreational releases
The natural flow of the Whakapapa River will be released downstream of the Whakapapa Intake for 8 hours between 9am and 5pm on the following dates:
- Saturday 20 August, 2016
- Saturday 3 September, 2016
1. Recreational releases from Whakapapa Intake require a minimum flow of 16 cumecs in the Whakapapa River. If the 16 cumec natural flow is not met on the Saturday, then it is deferred to the following day. If there is still insufficient flow, then the event is cancelled.
2. Please check the WWNZ website for details on the release. Updates on the likelihood of the release are posted 24 hours prior to the event and the final decision is made on the morning of the release.
