I read on the forum about Silolweni dam and it was said that its caused by the number of hippo's in the dam (I think), so if that is the case cant they just relocate some of the hippos to ease the problem or help sort it out.

I don't think it is easy to convince a hippo to move along. Even if they were successful to get them to move off, with the dam over the road from a river, new ones would just move in. At least if this dam has to be drained, the hippo and crocs will not have far to go. Although I am sure there will be some fighting to sort out territory.

Found the article - it is in the 21st May-3rd June edition of Kruger Park Times. Perhaps someone more computer savvy than me can find a link for other 'mites to read?

No - that is not the one, although Lynette Strauss is the author.

Hippo feces in the water is the root cause of the blue green algae taking a hold in a dam, and if there are to many hippos, then you have a bigger problem and build up.
Sunset dam luckily has a constant flow of water being pumped into the dam, so it does have a certain amount of water getting flushed through it, unlike some of the other big earthen dams that are a 1 way stop for the water.
Luckily in dams that have a flow of water moving through themb the algae tends to not build up to levels that are dangerous enough to kill animals.
One must also remember that this algae is naturally present in most of the water in the park, it is just the levels of concentration that cause a problem.
It is also not all algae that are poisonous, so if you see a bit of algae it may be a harmless type.

Sunset dam being near the Sabie river helps a lot as there is a ready supply of fresh water available to pump into the dam to dilute and flush the algae.

The problem in dams will be worse in winter because of two reasons, there is less rain water flushing the dam, and more hippo tend to hang about in the dam as seasonal pools they may inhabit in summer will dry up so they seek out new "homes" for the winter.

To move the hippos away will not help as they will just return to the dam, or other hippos will soon take up residence in there if the territorial group is missing for a while.

I am sure sunset dam will be fine though
:D

Saw that lots of the rivers in Kruger had this "green" grass looking stuff on it, :hmz: wonder what it is. Does anybody know what it is?

I think Kruger will soon have to include hippo on their culling list.

isn't this caused by the hippo dung and the water not moving fast enough.

hippo culling = hippo steak and hippo biltong pretty soon ??

Once again, a man-made problem... wouldn't be happening if the rivers weren't dammed... we saw the blue green algae sign at Nhlanganzwane Dam last weekend! It's sad that we have think of culling Hippo's as a solution..

And there wouldn't be a need for dams if there wasn't a need for a fence.
And so it goes on ad infinitum.
