Healthy waterway report Joshua miller
Christchurch Waterways
Fresh waterways in Christchurch include rivers, streams, wetlands, lakes and more. Man-made waterways include stormwater systems, piped systems, water races, artificial drains and some others. When it rains, if it goes on to concrete it falls into the gutters, then flows into the drains, then the river, then the ocean.
Habitats
A habitat is a home for animals and insects to live, and it makes shelter and shade and provides food to eat. An ideal shelter for a fish is under sticks lying around for shelter. Most of our rivers and creeks are polluted because people are littering making our waterways unhealthy. We need to stop - this is where they live and they may get stuck and die.
Everything in a habitat is connected
Crayfish relies on the common bully because the freshwater crayfish eats the bully. The eel (tuna) relies on the freshwater crayfish because he eats him, and if he wasn't there the eel would have no more food, than the eel would die. The eel and the duck connect because they both like shade. The bully and the mayfly connect because the bully eats the mayfly. The mayfly likes fast flowing water. Everything is connected to something else in some way, so we need to look after all of it.
Healthy or Unhealthy?
Invertebrates
You would find macroinvertebrates in healthy water, but in unhealthy water, there would only be snails and worms or you may find nothing, because the water may be too warm. Why? Because macroinvertebrates like water that is 15 degrees or under.
Water temperature
The water temperature depends if the water is murky. If it is it would likely be 20 degrees celsius and over and if the water was clear it would probably be 15 degrees celsius or under.
Algae
Algae is a tiny plant that lives in the water. They create a slimy layer on the surface of rocks. Algae can be good or bad. If there is a big thick mat it is unhealthy, but if there a small thin layer it is good.
Streamflow
A variety of depths and flow rates provide a greater range of habitat types. Deep pools make good fish spawning areas. Rapids and riffles help oxygenate the water and make good habitats for invertebrates.
Submerged plants
Underwater plants are a vital part of the freshwater environment. They provide food and habitat for fish to live and breed and hide from predators. They also play an important role in keeping waterways clean and healthy.
Erosion
Erosion is when dirt or sediment falls into our rivers
and creeks, lakes and more, making waterways unhealthy.
Method
Our class visited many waterways in Christchurch including Dudley creek, the stormwater drain behind our school and the Styx river. We used an “In-stream and Riparian Habitat Survey” to visually test the ecosystem. We also fished out macroinvertebrates using a technical retrieval device, also known as a sieve on a stick. We also tested how clean the water was by using turbidity tube. A turbidity tube is a long ttube that you fill with water and there is a disc in it. If you can see the disc into the end it is clean but if you can see very close it is bad, unclear and unhealthy water.
results
The stormwater drain behind Waimairi school is unhealthy. This is because there is no shade over the waterway. If there were trees and shrubs it would be colder but there are no trees and shrubs so macroinvertebrates will not live there.
75% of the stormwater drain has hardly any stones. This is bad because it has no hiding spots for macroinvertebrates and they can't breed.
As well as this the sides are very unstable over the waterway, and half of the waterway is eroding or breaking. This is because there are no tree roots holding the bank together.
The stream also flows straight and at one depth with no variety. This is bad because animals like the mayfly like fast flowing water.
Suggested changes
Although there are parts of the waterway ecosystem that are unhealthy, there are many changes we can improve its health.
plant trees and shrubs to give the waterway shade. And hold the bank together.
Replace the dirt and put stones in so macroinvertebrates can hide and breed.
Why these changes are important
These changes are important so we can swim and play in
our waterways. No one wants to swim in a polluted river, and a lot of macroinvertebrates and fish and ducks will love making it a great place to be, like fish will search for macroinvertebrates. A lot of people will visit the stormwater drains like classes and other locals we see it daily because it is by a main footpath.
It is also important to look after our rivers because we want to respect kaitiakitanga. Kaitiakitanga is a Maori cultural value that means to protect and care for our land and water. We want people to be able to love our rivers in future so we need to keep them healthy.

Snake bit cat
Hissssssss hisssssss.
It was a cold day. The wind was pushing me from behind. That wind zapped up my spine. It felt like a thousand little men trying to climb the biggest mountain in the world.
Hope was in the playhouse, the 2 ft high and 3ft long playhouse. Two cats were slowly walking around like something was going to happen. I looked at the cats. One of the cat's’ fur stuck out like a hedgehog and its eyes were as big as marbles.
I gasped, then suddenly- hisss hisss. Out of nowhere a snake slid as slow as a snail towards one of the cats. It was hiding in the grass, camouflaged. The scared cat watched the snake like a hawk, while walking backwards.
The snake emerged closer to the cat. The cat scanned the area to see if there were any hiding spots. The cat was looking at the tree. It ran as fast as a cheetah. The snake slid to the cat. I dived towards the cat trying to save it but noooooo! The snake opened its mouth then it closed. Fur gone, drowning to the ground. I gasped. My uncle ran out and stomped on the snake head with his rugby boots -squash! The snake’s head was a flat screen TV. I turned my head for a second and it was gone. The cat was paralyzed and he looked stuffed. We ran to the closest vet. My uncle went in, then came out.
“He is fine but he is paralysed,” he said sadly, “but only for a day.”

Autumn comes late
The cold grew and the wind blew
Leaves drowned to the ground, forming
A damp, leafy carpet. I heard brown
Leaves crunching under my feet.
Crunch, crunch. Drips of rain snake
Down my neck.
