HORSESHOE LAGOON ON WALLPOLLA ISLAND
At 9:30 the Enviro Team departed to Lake CULLULLERAINE to look for fish ladders , bird exhibits and the lock. I was sitting up the back of the bus with Maya, Teagan and Abbey. When we arrived we went to listen to Steve, the Lock Master and Andrew his assistant about why we were visiting Lock 9 and how the water is controlled by the weir.
After that we played a game called ‘YES BUT’, it was fun. Next we went to Wallpolla island where we had lunch we saw Dedmans Creek and HORSESHOE LAGOON. We walked further into the bush and had to guess what animal species lived in the area.
After that we went back to the bus and drove back to school and once again I sat up the back but with Teagan, Maya, Abbey, Steph and Sophie. It was a fun trip! I have learned heaps during this trip. Hopefully I can go on a trip like this again.
On Tuesday 21st of July 2009 the MWPS Enviro Issues Student Action Team went to Lock 9 and Walpolla Island. When we arrived we walked across the weir. On the other side of the weir we walked across the top of the sections of a fish ladder. It was scary!!!
Then we went back over the weir and we saw the Murray River flag ( I didn’t know it had one). Courtney took this awesome photo of Shona throwing some dirt and some boys accidentally threw a lemon in the water. Then we got back on the bus and headed for Horseshoe Lagoon. It was the most beautiful thing I have ever seen.
We ate lunch at Horseshoe Lagoon and then we went up through the bush with Paula. We played a game where we had to guess different species of fish, birds, snakes and frogs. I learnt that:
- The Lock 9 was completed in 1923.
- The flag was first raised in Goolwa.
- There are no snakes in the area.
By the way did anyone know any websites with information on fish ladders? If so please leave a comment.
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.
I learnt about
• Goolwa was where the river flag was first raised
• They started to build Lock 9 in1923 and finished in 1926
• Log bays help regulate the river by stopping the flow
• The fish ladder looks like a maze
The machine picks up the logs and puts them in the slots. When the flood comes they take the logs out so that the next lock can get some water. They do that when they get enough water and the cycle goes on. It takes about half an hour to start the machine up and pick up the the log and put it in the slot.
• The types of snakes that live around Lock 9 are
• Brown snakes
• Red Belly black snakes
• Tiger snakes
Did you know the Murray River Flag first appeared at Goolwa to honour the first Paddle steamer on the Murray River.
There are 2 Murray river flags. This picture is the Lower Murray Flag. The blue horizontal bars represent the 4 rivers in the Murray Darling Basin: Can you name these?
Does anyone know what the Upper Murray flag looks like?
On Tuesday 21st July, Mildura West Primary School Action group students travelled to Wallpolla Island and Lake Cullulleraine. We learnt cool facts about the Murray River and Regulating the river. We got given note pads and had to write down what we learnt I wrote 6 whole pages of what I learnt.
Walking across the weir at Lake Cullulleraine was the best feeling probably because there was no barrier next to the River Ahhh! The fish ladder was awesome, I loved how the water raised when we followed the fish path. It was a restricted area that was a rare opportunity and off limits to normal civilians. When we got home I told Mum where we had been and she was jealous.
It was a great trip and everyone was well behaved and I hope to go on more in the future at Mildura West.
Last year in June , 2008 when the weir was removed for maintenance and the water turned back to its natural state it shocked many that the water was very low. It looked like we were heading into one of the most serious shortages of water ever. My family and I were amazed by the state of the river. We ended up taking a lot of pictures and staying at the river for hours.
What was even more amazing was the amount of rubbish that was tucked up in all the sand and dirt. There were glass beer bottles, millions of cigarette butts, rubber, marbles and many other things. Once the water rose again that pollution would soon harm our waterlife.
Another location we visted the water was down low; it was about 3 metres further down than usual. You couldn’t walk down to the water because it was very steep and rocky but what I noticed was some yucky, yellowish creamish coloured frothy foam sitting on top of the water in some places. It was revolting.
It just goes to show that our weirs do keep parts of our river in a healthy state and that we should stop polluting our waters.
