Groenvlei Lake

Groenvlei Lake is 5 km east of Sedgefield. This is a unique lake.  The lake is not large, maybe 4 km long and 1 km wide, it is also not deep, the maximum depth being around 3 metres with very few deeper sections which go up to 5 metres deep. It covers an area in excess of 3 square kilometres. The water in the lake is clear but has an aquamarine appearance which is caused by the reflection of sunlight on green algae against the light-coloured lake floor and the greenery in and around the lake. It is a freshwater lake that has no recognisable inlet or outlet. It is said that the water seeps up from subterranean channels via springs and is slightly saline. Depending on rainfall and evaporation, the levels in the lake can fluctuate by nearly 2 metres. The lake is still a very popular and pleasant place to swim.

Several species of fish have been introduced to the lake, such as  Black Bass, Mozambique Tilapia and Carp. The decision to introduce these species was taken before the long-term consequences of this action could be fully understood. Groenvlei has no rocks, points or drop-offs to speak of.  There are also random patches of grass in other parts of the lake. The island in the centre and the lake is known for its diverse birdlife.
