LOCK 9

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

History and present information about the Murray River

At Wentworth in NSW the Murray River joins the Darling River and this is called the junction of both of these rivers. It is not very far from Mildura.  In 1830 the famous explorer Captain Charles Sturt discovered the junction while he was following the Murray to South Australia.  There is a picnic area for people to enjoy the view.

Regulators

 

Someone asked about regulators on one of my posts. Now I am going to provide the answers.

Regulators try to create a more natural wetland environment, where flooding and drying occurs. You’re right, when water is kept in the lagoon by closing the regulator gates, it helps the trees and other vegetation to get a good soak. Then over summer when it gets really hot, the water in the lagoon evaporates leaving the lagoon dry. It will remain dry until the next Spring when it will flood again.

Regulators can also keep water out of wetlands that are always wet. Being always wet is like being always dry…it needs a bit of both.

Regulators are expensive….but there are smaller, cheaper ones. You should talk to the Mallee CMA about your little wetland…they might be able to help you improve it’s health for the wildlife.

What do you think?

A good excursion to Wallpolla Island.

Wallpolla island was great fun. The trip there and back was a bit bumpy and it really shook us around. Brendan our tour guide thought that we weren’t going to be able to cross the creek bed because it had rained the night before hand.

When we got to the creek where we crossed over we found out that we could cross because the water had dried up. We got through and had a look at the dying trees and it was sad. Seeing such big, huge trees look like sticks is scary. The drought has caused this and the trees just don’t get any water. That’s why it’s so important to use your water wisely. If you think about it we get water and we are nice and healthy, but the the trees are not so healthy and don’t get any water at all.

So then we went a bit further and saw Horseshoe Lagoon and Dedman’s Creek. At Horseshoe Lagoon we saw the regulator and it cost 1.5 milion dollars. When Brendan said that I thought ‘Wow! Thats heaps!’

How a regulator works.
. Gates to open and close it
.Carp screen so carp or big fish don’t get in
.Lets water flow
.Lets water flow naturally

Then we got to the Murray River and had lunch there. It was a great view!
Hope you enjoyed my Wallpolla Island recount as much as I enjoyed the visit.

Thank you Shantelle

Do you know everything about me? Find out!
Yours sincerely
Murray Cod

I am the biggest fish in the Murray. My biggest possible weight is 113kg. Did you know that 1.8 m is the largest length that has ever been found in my family! Usually we grow to about 45-65 cm. If there were more of us there would be less Carp, our enemy! Murray Cod and Trout Cod breed together when our immune systems are down!

Do you know the rules?

– Some of the rules are if you catch a fish under or over the limit you have to put it back in the water.
– Another one is if you catch a carp you are not allowed to put it back in the river but you can eat it if you have a great recipe.
– If you are 18 or over you have to have a licence to fish.

Mildura R.S.L. Angling Club Letter

Dear Mildura R.S.L. Angling Club Members,
Thank you for your lovely hospitality. The food was delicious, also for the supply of the drinks (it was good we had 3 helpings). If we had another BBQ we would choose you to cook it! It was great.
Once again thank you.

Letter thanking Mr. James for the fingerlings.

Dear Mr James,
Thank you for coming down from Wagga Wagga to bring down the fingerlings. It was really fun releasing the fingerlings. We all got a chance to help increase the fish numbers in the Murray River. Thank you for answering our questions.

MURRAY COD AND YELLOW BELLY FINGERLINGS RELEASED INTO THE MURRAY RIVER

On Tuesday 18th March 5/6B, the Water Ambassadors and the Enviro Student Action Team went by bus to the Rowing Club Lawns in Mildura. We were there to release 40,000 fingerlings: Murray cod and yellow belly perch. 

 First we went for a 10 minute walk. We went above the train track and then to the skate park. We headed back and the Mildura RSL Angling Club shouted us lunch: a sausage sizzle, a drink of coke, creaming soda or lemonade.

After lunch Peter Crisp came to speak to us and told us as much as he knew about fish. The man that had the fingerlings came from Wagga Wagga. He had all the fingerlings in a special eskie in the back of his ute.  

We got into groups of 4-5, got a bucket and put some river water in it. Then we had some fingerlings put into the bucket. Some of them died of fright! We tipped the bucket gently into the river to release the fingerlings. The rest of the fingerlings that were in the bottom of the eskie were released by the ‘fish man’ using a pump from his ute. The fingerlings looked as though they were flying out in a water spout into the river. We hope they survive.  

After that we caught the bus back to school.
