The clarity is amazing.
But be careful below the dam.
I have fished the stretch from the dam to about 100km down stream.
They are suppose to sound the siren when they are opening the sluices for electricity generation, but on more than one occasion the FAARCKERS DID NOT SOUND THE SIREN.
The water rises by about 1,5 to 2meters in a matter of minutes. Before you realise it(2 or 3 minutes), the water will be 50cm plus up, then getting out from the middle of the river, is all ready dangerous.
The same applies to the GARIEP DAM. There are documented cases on FLYTALK of guys, very nearly getting into serious trouble with the rising water.
