disappearance of water in scene mode...

Good evening
I am finishing a little world on unity 5.4.2
I have a small problem - the water in scene mode has disappeared. I do not know why.
In game mode I see it very well.
I had to press a button somewhere.

Can someone lead my research

ok friends I found my problem of invisible water in scene mode.
I went to Gizmos and saw that the camera script was disabled.
I activated and everything went in the right order.
