johnsa, what you see there is POISON. Here are a couple of extracts from an editorial of the local newspaper. It is outright scary !
"Hope for the Dam
The Department of Water Affairs and Forestry (DWAF) in an effort to send out a message of hope, invited members of the media to a technical briefing session last week where the remediation project and its different components were amongst others presented.
Petrus Venter, Deputy Regional Director; Water Resource Management in the Northwest discussed the present state of the Hartbeespoort Dam which has for a number of years already experienced unacceptable high levels of algal blooms. This has according to the Department had a negative affect on the water quality in the Dam, the water usage from the dam, the aquatic ecosystem and the environment.
“A large number of projects have been undertaken in the past to investigate and address the problem, with little success. Some of the actions that took place include the establishment of the Hartbeespoort Water Action Group (HWAG) in 2001 and toxic algal cleanups in 2001 and 2003.
Venter gave a brief background on the problems experienced and these can be summarized as follows:
* The dam is in a hypertoxic state, about 50% of the water originates from urban return flows,
* recreational activities on and around the dam are severely impeded,
* Excessive growth of algae and water hyacinths are taking place,
* Drinking water treatment is increasingly becoming problematic,
* Fish population in the dam is imbalanced, and
* Downstream users are adversely effected by periodically released poor quality water.
The focus activities in the program addresses incoming water from the Crocodile River and suggests treatment to reduce the phosphate load; building of a pre impoundment wall to retain sediment and treated phosphate; removal, treatment and disposal of sediments; management of permanent wetlands and establishing a litter trap.
Upstream catchment focuses include education and awareness, establishment of an integrated monitoring program and updating of phosphate loading for diffuse sources.
Venter said he believed that they had the ability to make a difference through creating awareness. He concluded and said that the Dam was in quite a good state at the moment but warned people to stay away from toxic algae which is expected to be around again during the hot summer months."
And the summer has barely started and already it looks like it does !

Still its nice to live there especially at the old cosmos, good people good atmosphere and not far from fourways and most people have there own swimming pool
The first time I'd tried to fiend Harties on Google, it took me about ten minutes. I just couldn't see it. I eventually followed the road from Pretroria to the dam, and then saw why I couldn't see it.
Being colourblind also did't help.
Bronkies did look a bit better on Saturday.
