Someone on the Global Bird Trekkers forum mentioned that he had seen hundreds of Black-necked Grebe's at Leeuwkuil Dam - which is on the edge of Sharpeville outside Vereeneging. I spent a few hours there on Monday morning the 3rd of September 2012 and was blown away at the sighting of hundreds of Black-necked Grebe. By the time I left the spot I had recorded 50 bird species. Here are a few of my best pics (it is hard to get close to the Grebes as they tend to stay away from the shoreline).

There was a Duck among the Grebes - it could be either Maccoa Duck or Southern Pochard but I am leaning towards a female or juvenile Maccoa Duck:

Here is a full list of the species I saw around the dam: Grebe Black-necked, Flamingo Greater, Avocet Pied, Swift White-rumped, Grebe Little, Pochard Southern, Duck Maccoa, Duck Yellow-billed, Shelduck South African, Coot Red-knobbed, Goose Egyptian, Swallow South African Cliff, Ibis Hadeda, Teal Cape, Gull Grey-headed, Stilt Black-winged, Lapwing Blacksmith, Martin Brown-throated, Pigeon Speckled, Weaver Southern Masked, Wryneck Red-throated, Heron Squacco, Myna Common, Teal Red-billed, Pipit African, Heron Grey, Swamphen African Purple, Dove Laughing, Swallow White-throated, Plover Kittlitz`s, Cormorant Reed, Darter African, Duck White-faced, Plover Three-banded, Heron Black-headed, Greenshank Common, Fiscal Common, Sandpiper Marsh, Ruff, Moorhen Common, Jacana African, Swift African Palm, Shoveler Cape, Egret Cattle, Sparrow Cape, Bishop Southern Red.

Directions to the spot: I headed to Vereeniging on the R59 and then took the R42 and turned first right at the robit at the Makro and then first right at the robot. This took me along the southern shoreline but the Grebes were in the area on the northern shoreline which required some creative off road driving to get there. There is a huge half demolished/abandoned building on the northern side of the dam that is where you need to be heading to. In terms of safety it did not feel safe at all. I did have a few conversations with people from Sharpeville during the morning who approached me but on some occasions felt the need to get in my car and move away from possible risky situations. I would recommend going with others rather than alone as I did. Here are my iMaps coordinates to the spot closest where the Grebes are: -26.679041, 27.887867

Here are directions from a fellow birder: We took the R59, then took the Boy Louw street offramp (R 28), we turned RIGHT, crossed the bridge, then turned left at Lager Road, and right at the junction into Seeiso Street, follow this road for a few hundred metres and you will see some picnic tables next to the dam on the left hand side.
