Andrew and the ambassadors with Cam Speedy from Genesis Energy and Krysia Nowak from DOC on this morning's web conference. Image: LEARNZ.

Some water at the Whanganui intake is taken and used at Tokaanu Power Station to generate electricity. The rest carries on down the river. How does Genesis Energy make sure there is enough water flowing down the river? Image: LEARNZ.

The Whanganui River as seen from Whanganui Intake. How many different uses can you think of for the river?

Lake Otamangakau used to be more of a wetland than a lake. How did it become a lake? What might the lake be used for? Image: LEARNZ.

This is where water is released from Lake Otamangakau. It is also where elvers (young eels) get to on their migration up the river. I wonder how the eels are gathered from here to be transferred to the lake. Image: LEARNZ. 

Water from the lake is let down this type of fish ladder. The elver travel up because they think it is the way to the lake. I wonder how the elver know that the water they are travelling through is from the lake. Image: LEARNZ.

The fish ladder ends up in this tank, and so do the elvers. They are collected from here and transferred to the lake. Image: LEARNZ.

Here you can see part of a Project Tongariro restoration planting site next to the Tongariro River. I wonder why the young plants have coverings around them. Image: LEARNZ.

Emma and Anahera prepare to plant a tī kouka/cabbage tree at the Project Tongariro restoration site. How does planting next to a stream or river help the wildlife? Image: LEARNZ.

Students Para, Tiaho, Anahera, Emma, Conall, Grace, with Krysia and Andrew and the ambassadors. Is there a restoration project near you that you can be part of? Image: LEARNZ. 

Michel Dedual, Andrew and Egbert (plus Eddy the whio) listen as Krysia Nowak answers another question on this morning's web conference. Image: LEARNZ.

Michel Dedual at the Waihukahuka fish trap. Why are DOC fishery scientists trapping trout? Image: LEARNZ.

Michel shows a rainbow trout on its way upstream. Why is it heading upstream? Image: LEARNZ.

Part of the monitoring process involves weighing each fish. What else is done? Image: LEARNZ.

Drift diving is another way of counting trout. I wonder how accurate this method is. Image: LEARNZ.

An angler tries his luck in the Tongariro River. What method of fishing is this called? Image: LEARNZ.

Mike Hill from DOC surveys an angler on the Tongariro River. Angler surveys are an important part of future decision making for the trout fishery. Image: LEARNZ.

Peter Wilton from the National Trout Centre Society teaches Lenny from Kuratau School about the use of flies for fly fishing. Image: LEARNZ.

Lenny tries her luck at the kids fishing pool outside the Taupō for Tomorrow classroom at the National Trout Centre. Have you ever been fly fishing? Image: LEARNZ.

Lenny proudly shows off the rainbow trout she caught with the help of Peter Wilton. Image: LEARNZ.

Garth Oakden is the owner of Tongariro River Rafting. It is a great way to get up close to the river and its wildlife. Image: LEARNZ.

It is lots of fun bouncing along down the rapids. Image: LEARNZ.

Whio are becoming a more common sight on the Tongariro River. What has helped their numbers grow? Image: LEARNZ.

Predators like these stoats are targeted in a network of traps along the Tongariro River to help whio populate. Image: LEARNZ.

Krysia and James collect macroinvertebrates from the Tongariro River. What can the presence of macroinvertebrates tell you about the river? Image: LEARNZ.

Krysia and James carefully empty the macroinvertebrates out of the net and into a tray of water. Image: LEARNZ.

What animals might eat these macroinvertebrates? Image: LEARNZ.

The aquarium and the National Trout Centre. Why does it need to be kept cool and dark? Image: LEARNZ.

This giant kōkopu is one of 5 types of what that are commonly eaten in New Zealand? Image: LEARNZ.

Kōura, also known as kēwai, is New Zealand's freshwater crayfish. Image: LEARNZ.

This common bully is not so common after all - at least not throughout the rest of the world. It is only found in New Zealand. Image: LEARNZ.

Andrew and Egbert at the airport in Kerikeri. Image: LEARNZ.

Heading to the Bombardier Q300 aircraft at Kerikeri airport. Image: LEARNZ.

Not long after takeoff we headed into this rain cloud. When thinking of the water cycle, what is the scientific name for rain, hail, and snow? Image: LEARNZ.

A river snakes its way through farmland towards the Kaipara Harbour. What can farmers do to reduce their impact on waterways? Image: LEARNZ.

A river enters the sea just north of Orewa, Auckland. Image: LEARNZ.

What are the potential impacts to water quality that you can see in this picture? Image: LEARNZ.

This river flows into the Manukau Harbour. How might it impact the marine life living near it? Image: LEARNZ.

Heading south, I found the shape of this river rather odd. I have no idea what river it is - I wonder if you know. Image: LEARNZ.

After a snooze on the plane I woke in time to take this picture of Lake Taupō. Image: LEARNZ.

Welcome to Tūrangi! Image: LEARNZ.
