    Default Vaal river color

    I have been fishing the Vaal river for a few years now and never before can I recall that the river was that grey as I saw this weekend.
    The color was a grey silver brown. Late afternoon with the sun behind you it is actually beautiful and different, not like the normal brown.
    The area is below the barrage: Arendsnes.
    I can understand that with lots of rain the river turns to a brown mud color, but can someone explain the grey color for me.

    The colour at Erina Spa yesterday was the same colour that you will find above the Barrage and in the Vaal system from the Dam wall upwards.
    DWAF have opened and closed sluices over the last 2 weeks. Over the weekend they had 4 river valves open at the dam, which in effect drains the dam from the bottom, hence the colour due to the sediment. With the barrage being so full and a lack of rain over the last few days, I think that this coloured water has just carried on through the barrage and further downriver.

    Reveck, any comments ?
    It's not in the catching, it's in the learning something new.

    When I did the elgro drift wednesday I saw the nice greyish color - but the weekend it was back to brown where I was fishing lower down. I found the fishing in the grey water easier - I think viz might have been slightly better.

    I can understand that the brown comes from mud flowing into the river.
    The grey I quest must be from some rock sediment in the certain areas above the barrage, not sure.
    If it is then it is inconsistent and the mud inflow is always more dominant during rainy and non rainy periods.
    I found the visibility of the grey not better than the brown?

    Mud/particulate sediment/soil is brown.

    Grey is untreated effluent.

    That is not good.
    My smell senses is not good enough to state that the river smelled different than before.
    It means it must be tested to confirm the water character.
    Oeps and I was not using my wader and a lot of other water users as well.
