Not sure what these silly salmon are waiting for?
This is NOT their spawning grounds. They have to get over the falls, past the bears and through at least one more large lake before they reach their spawning tributaries.
And they are all lined up in nice neat rows and columns, as you can see on the above water cameras when they are looking down at the river.
All I can figure is that these are the ones that are either too tired or too lazy to get over the falls and have given up.
They may actually try to spawn here, but nothing here is likely to survive as the water is too deep and too fast flowing.
Still, it is an interesting sight to behold.
