Not many folk know of the "Karoo Gold Yellows we have around the Darlington Dam and Somerset East areas.
All small mouth and beauties.

The winter months are the best for the yellows around here as they close the canal from Gariep for maintenance and the rivers run nice and clear.

If anybody is coming down this way drop me a PM and I will gladly give you directions and contact numbers of the farmers in the area
