Diving inland in South Africa/Miracle Waters
Miracle Waters is a flooded Chromium mine located 10km NW of Hartebeespoort Dam, about 90km NW of Johannesburg, with ~6 hectare surface area. An entrance fee is charged to divers. Air fills are available on site, as is Nitrox, and diving gear is available to rent. There is a restaurant, ablution facilities, and a number of lapas available to divers. There are also rudimentary cottages available. Camping is permitted, however the main gate is locked overnight.
There is a large tree-shaded picnic area with tables and benches.
The lake has a maximum depth of 33 metres. There are several grids in various locations. This lake is used primarily as a training location for Johannesburg-based Open Water diver training schools, along with Bass Lake, however it is also a popular recreational diving destination for those who live within a few hours' drive.
Water is fairly warm, however there are several noticeable thermoclines at approximately 12, 17, and 21 metres. The water is very still, with no waves. Visibility is moderate, from 10 metres down to 5 or less after much diving during the day.
Miracle Waters are located at 25°40'37.94"S, 27°45'27.76"E.
