Overcast with light rain falling in Turangi as of 8:45am this morning. No wind as of 8:45am. The Tongariro River is highly fishable flowing at about 22.2 cumecs.
The rain that we have had over the last few days has just been nice and gentle and has been good to soak into the dry ground. It was pretty humid here in Turangi yesterday and with that humidity and heat I did hear a few cicadas. Heavier rain is forecast later in the day.
This rain is really quite good. This should bring some good fresh rainbows up the rivers as the early runs will be getting going from now on. Always remember that early season you will experience a trickle of rainbows and these numbers will build as we head towards Mid Winter and the Spring. This rain should move some fresher browns up river too. They tend to spawn before the rainbows and their numbers should continue to build as we head towards May ( flood and weather dependent ).
Just a reminder below to keep this in mind with the work being carried out that river levels will be up a bit and also that they COULD GET PRETTY HIGH if it rains over this time. Keep in mind the thought that if you cross to an island you may not be able to get back with the uncontrolled flows. The last time something like this happened a few years ago I think the river sat at about 50 cumecs for the time the work was carried out. During this time I did more wetlining in the faster flows and this was pretty good.
Genesis has upcoming maintenance work that will result in higher flows than usual on the Tongariro River for much of March.
From Saturday 6 March to Friday 19 March, the Moawhango and Rangipo Intake Tunnels will be inspected. This work means flows from Rangipo Dam to Poutu Intake will be at natural levels, and more subject to natural fluctuation. This work will also require a flow discharge into Waihaha Stream of up to 3 cumecs, so please be aware of higher flows than normal in this stream and its crossing on the Tree Trunk Gorge track.
Then, from Monday 22 March to Wednesday 31 March, the Poutu Tunnel and Canal will be inspected, affecting the flows downstream of Poutu Intake, including at Tūrangi township. These flows will be approximately 15-25 cumecs higher than what is normally seen in the lower Tongariro River. Flows will also be higher in the Poutu Stream during this period.
Due to the nature of the work, either or both inspections may be completed and the river returned to its usual flows before the end of the periods described above.
Please be aware that these flows will also be subject to natural fluctuation and generation flow change at any time.
Please feel free to share this information directly or via social media with other river users and contact me if you have any questions. Flow information can be found on the Genesis website.
