They say a river never stands still and that is certainly true.
The Bervie is a pretty good small salmon river – that's a small river with salmon, not a river with small salmon; in fact the Bervie is noted for producing some very large salmon indeed although to see it at summer levels you might find that hard to believe.
Short, steep spate streams like The Bervie are often subject to sudden huge rises in water levels that can bring about dramatic changes as well as coaxing fish in from the sea
The pictures below are at Corbie's Pot, a well known salmon “hole” downstream of the A90 at Mill Of Mondynes. In the first photo you can clearly see where the river used to flow round in a loop and where over the years eroded the red clay bank.
The river now takes a somewhat more direct route and has cut the corner as seen in the second photo.
The power of rivers, even small rivers like this, is astonishing.
