I'm not a scientist but I don't think that's the same as the Micocystis algae. I think the bright green stuff is called 'Zola' I don't know the scientific name. The green stuff is very useful if you want to know where the wind is coming from. Even in the slightest breeze the green stuff will be moved in the direcion of the wind. The side of a dam where the green stuff accumulates is the side the wind is blowing to.

Last time I was there (2006) bucky, the viewing was not great, so hopefully they will get clear the way for the road to get a bit closer also.

At the loss of one animal dying because of this man-made malady, I hope that the dam is breeched sooner than later. It's difficult to accept when "our favourite" spots are no longer there, but I will gladly forego this in the hope that the animals remain healthy and alive.

Good Day

Tanks to all who posted responses to my questions earlier.
Also, SANPS Guru, thank you for explanations given.

I have a further questions, which i am not sure is discussed:

1.) This "toxic" algae, Micocystis, is it normally found in the River Dam systems in the KNP areas? that is in "non-toxic" amounts? If not, where does it come from/ introduced?
2.) Does higher faecal/ urine concentrations in the water encourage higher amounts algae to grow? if water source remains fairly constant
3.) do Concentrations algae naturally rise as water source diminishes, if (2) is not a contributing factor?
4.) Do Hippos die from exposure to the Algae? or are they somehow immune? Are Hippos the X factor in the problem?
5.) What of Water Birds being carriers/ distributors of this Algae. Any deaths noted of Herons/ Ducks etc at affected Dams?

Any clarity/ discussion on above would be appreciated.

Cheers

If I remember correctly from an article in a Kruger Times of a year ago, the algae causes a fatal liver problem in animals that drink the water.
Not sure if birds are affected as well and yes, should think its caused by high faecal /urine count that is exacerbated by a low water influx problem.
So, altho in Sunset dam's case, the water level might not be that low but its the through flow what counts.
as I see it!! :? but I stand to be corrected.

Nhlanganzwane Dam

Hi Guys

I noticed work going on at the old Nhlanganzwane dam two weeks ago (Off the S28 between Lower Sabi and Crocodile).

Does anyone know whether they are planning to re open it??

Shouldn't imagine they are reopening it in line with the new water policy? :?
Maybe the Working for water folks removing alien vegetation etc?
Will try and find out.
