If you are in the park today or know of anyone in the park, spread the word to get to the Olifants River. The water board at Phalaborwa have opened the sluice gates at the barrage at 03H00 this morning. There will be huge volumes of water making it's way down the river and it should make for good viewing. :thumbs_up:

One could see Hippo's flock together to get away from the force of the water

Or see the normally complacent river turn into a raging bull :lol:

Just a pity that the Massingir dam will prevent a good flush of the Olifants river system. Lots have been reported about the poor state of the Olifants, with bird, fish and other water dependent species on the decline.

I still think that this is the year Kruger floods again...Letaba and Olifants have burst its banks...

Just a quick question on hippos and crocodiles in the river at the moment, I have read and heard that they are able to somehow know if a river will flood and will move out of the river for safety. Are they now vulnerable to humans opening flood gates and creating their own "flood"? Will they have warning of the oncoming waters and will they react the same way as in a "normal" flood? Would anyone guess what impact this man made flood will have on the crocodiles in the gorge?

I am no fundi, but the following have been recorded about animals' ability to predict possible disaster. During WW2, 2 Germans fled into the Namib desert to prevent them from being arrested and put in an internment camp. They found a place in the Kuiseb canyon to stay. One day they were sitting next to a pool in the river bed, when suddenly the frogs started to scramble out of the water and move to higher ground. It was very strange to them, but an hour or so later, a wall of water came gushing through the canyon an swept everything in its path away. Apparently, there was a cloud burst many kilometres upstream. Somehow the frogs could detect that problems were on their way and therefor escaped the danger. The Afrikaans name of the book is "Vlug in die Namib" There is an English version, but I keep on forgetting it.

According to Parks officials, no animals were killed by the 2000 floods.

As far as the crocs are concerned, it was found that toxins from outside the park get washed down by the floods, and when the waters reaches the Massingir dam, the flow stops and the toxins then sink down to the bottom of the dam. Fish then swims through a curtain of toxins, and when the crocs eat the fish, they die.


Thanks Rooies, I am guessing the animals can sense when there was a change in the atmospheric conditions, and that is possibly how they would know if there is a flood coming. I do wonder that if there was no storm a few kilometers away, but humans open up dam flood gates, will the animals have warning of the oncoming waters?

I will dispute the claim that no animals were killed during the floods...what were the lions and leopards and hyena's eating at that time.... :tongue: :tongue: , just kidding, I would love to know how they know that. Surely there must have been a few animals caught up in the rushing waters, just like there are always animals caught in a fire?

Went over the Olifants on the Highveld yesterday, and seems to have calmed down a lot!

To add to weltenman's original question:

It is unlikely that opening a few gates on an Olifants dam will lead to catastrophic floods...that is why they are opened! :lol:

Plenty animals died in the 2000 floods, BTW! :huh:

Dear All,

Having experienced the 2000 floods and the aftermath, it would be my view that undoubtedly many animals would have died in this largely natural phenomenon. The key words in my sentence being "many", "animals" and "natural phenomenon". Animals would include all the little creatures such as snakes and small mammals. I remember at one of the camps there were countless snakes swimming tiredly after obviously having been flushed out of their homes in and near the river and having been glad to have survived, just lay on the shore to rest after the long swim. Undoubtedly many would have succumbed. The 2000 floods were largely natural in nature and yes, human developments would have played a role in perhaps the timing and extent of the flood. Nature works in cycles and just as, for example hippos and crocodile would die during droughts (eg 1992), some would have succumbed in flood, especially extreme ones such as 2000. So many creatures succumb during the annual advent of fires mainly during the dry season. We shouldn't get too emotional about these things as they are part of nature taking it's course and maintaining that vital balance.

Kind regards.

JOEP

Kruger has some big rivers that run through it for example the Olifants, Letaba, Sabie and Shingwedzi.
All of these rivers sustain wildlife in one way or the other but which one of these rivers are the most utilised by wildlife, indigenous plants and other life forms?
From a (simplistic) visible sightings perspective I would say it is either the Sabie River or the Shingwedzi River in the vicinity of the Kanniedood dam?

I've seen great variety of lifeforms on both the Letaba and Shingwedzi rivers.
Don't go south very often, but when I've been there in December, the Sabie was so full and fast that there was very little game and no water birds - quite disappointing actually, after being used to how well the rivers up north are utilised.

I think utilisation intensity of the various rivers may actually vary day-to-day, season-to-season, year-to-year depending on variables such as time of year, how dry/wet it is, the diversity of the surrounding vegetation etc.

All the rivers are utilized more or less on the same basis, except the Olifants river which is so polluted that some species that used to frequent the Olifants, have disappeared from the river.
The numbers of species like Pel's Fishing owl, Saddle Billed Stork etc, have declined drastically

spargish we also have seen a lot of life in and along the Letaba river, perhaps more than along the Olifants during our visits. I suppose the pollution levels of the Olifants river as indicated by Rooies has already and may even further affect the animal, water bird, aquatic and plant life in that river.
