Since the late 1960s the Hartbeespoort Dam (HBPD) has become increasingly eutrophic. In the mid-1970s the dam reached a hypertrophic state due to severe algae growth in summer months. These blue-green algae blooms pose a high risk to human health, and have a detrimental impact on recreational activities and the socioeconomic potential in the area. Secondary to the algae blooms has been the prolonged growth of hyacinths in the dam and upper catchment over the last 30 years. Rapid urbanisation, associated with increased runoff, erosion, sedimentation and solid waste entering the dam annually is a growing threat. If this problem is not addressed appropriately, it will result in a further decline in the local tourism industry, as well as negatively impact economic growth and development in the North West Province with regard to agriculture, mining, industry, recreation and entire aquatic ecosystems.
