Lake Ranfurly Quadrant Sampling
On Thursday 13th of August, 5/6E went on the bus to Lake Ranfurly. We then met a lady called Catherine, the Biodiversity Officer from Mildura Rural City Council and put on some yellow or orange safety vests. Then we followed the adults down a track that took us around five minutes to get to the other end. Surprised, we all looked out to the lake and spotted two kangaroos with their joey.
We paired up and I was with Sophie. I was given a clipboared and Sophie was given a flexible ruler.
We took ten big steps towards the lake and had a look around us, Sophie measured the plants and called out the information while I was madly writing down the feedback.
The plants we saw included pig face, salt bush and spiky bushes.
Some unusual things we saw were a goats skull and some kangaroo bones.
We took the information back to Catherine and headed back to school. It was very interesting and fun.
When I was crossing the weir it was interesting and fun to walk on. I saw the logs and I asked Mrs V if she knew how many logs go down into the river. We could only see 7 so I asked Steve how many logs go down into the river, he said 17 I imagined how deep it was! Big!
I didn’t know there was a flag for the rivers in the Murray Darling Basin The names for the rivers are Lachlan, Murray, Murrumbidgee and Darling. It was interesting to find out. It looks like there are 3 types of flags on it. The 4 horizontal bars represent the rivers in the Murray Darling basin. The stars on the on the right are the 5 states. The blue and white stripes at the bottom are the 4 rivers and the left hand side flag is the Union Jack.
One day I went to the river and it was beautiful. The birds were chirping and the fish swimming happily. I decided it was a perfect day for a picnic. I saw a chubby man fishing in a boat. He was eating a chocolate bar. When he finished he just threw the wrapper into the river. When the man came out I said to him,
“I saw you throw your rubish into the river, don’t you want to have a healthy wetland?”
He said, “What does a healthy wetland mean?”
“A healthy wetland is known as the kidneys of the river. Wetlands filter out all the contaminants so the water is cleaner just like our kidneys filter the contaminants out of the human body. Plants grow well in a wetland and many animals live there too. Don’t you want to see the insects and macroinvertebrates enjoying the clean water and the fish being able to swim safely instead of dying in contaminated rivers? Next time you should bring a bag to put your rubbish in. You could enjoy the river, the fish and listen to the birds. You’ll want to come here every day to visit the wetlands. Always remember the motto, what you bring in, you take out!”
“Oh I’d better go and clean up my rubbish, I feel really bad,” he said.
Six months later the man went camping to the wetlands with his family, but when they got there it was a big smelly disaster. There was rubbish everywhere. The man and his family decided to do something about it so they could clean up the mess. They organised some friends and volunteers to come and help. It was a big job and took them a couple of weeks. Everyone in the community found out about it; it was even on the news. The group received a certificate of thanks and the man made a speech. He told everyone that if you go to the river we need to keep our wetlands clean and healthy. We can all do something to save the environment and enjoy the river.
Everyone in the community kept the wetlands clean from then on. That man had spread important information on keeping our wetlands clean so that everyone knows we have to keep the wetlands free of rubbish as wetlands are very important to our rivers.
1. We need to make sure that we have enough water for us to drink also for animals to survive. Regulating the Murray River means installing dams, weirs, locks, fish ladders, barrages and carp screens. Some people think that regulating the Murray River is a good thing, while others think leaving it natural is the best way.
2. Carp is bad for river, so if people catch a carp you never put them back into the rivers. There is a fine if you do put carp back in the river. Regulators in the river help to control carp as they have carp screens and that keeps the adult carp out of breeding areas. Adult Murray Cod now like eating the baby carp and that is helping get rid of this pest.
A GREAT DAY!
Dad, Mum, my sister, my brother and I, went to the Murray River. The water flowed steadily and we played around. It was a great day to go to the river. We went on the weekend because we wanted to go there for a peaceful day at the river. I had my bathers on ready to go and have some fun. It was a great day the weather was not too hot and not too windy. It was a perfect day. I would love to go there again now that I’m a little older and go and see how the water was going.
Sometimes I went bike riding along the Murray River but not too close that we’re going to fall in. We kept a sensible distance from the river otherwise it would be very dangerous. I went sometimes with my brother and Mum, and sometimes with my brother and Dad, because I wasn’t allowed to go by myself. It is fantasic going bike ridding because you get lots of exercise.
I hope you enjoyed my experience at the Murray River.
