Overcast and very windy start to the day here in Turangi this morning… and cold. First few days of Autumn and we are into WINTER already !!!!
There was quite a bit of colour to the river here in Turangi on Saturday and Sunday. I saw a few bits of green mossy algae flowing down river over these days as well. Those conditions should have been ideal for the wetliners. This should have been perfect condtions to catch a brown trout on the wetline.
This cold snap and bit of rain should bring the first lots of rainbows up-river. The water temperatures will have cooled and this may entice some of these early running fish to start their way up-river. The numbers of these a not great at this time of the year but they trickle in and continue to build as we head toward the Spring.
Dry fly fishing has tapered off with the cooler weather but in saying that still keep your eyes peeled as I had a rather large Kakahi Queen Mayfly on the outside glass of my door yesterday. We may still get some Mayfly hatches. I am seeing less and less Passion Vine Hoppers now as well.
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.
