Black triangle UFO accidentally caught on drone cam in underwater lake?

I was just checking this lake out because I’m thinking of camping there next week. So I check this YouTube vid out, and around the 0:26 mark, on the right hand side of cam, a triangle formation of lights can be seen.

Coincidentally, this lake Bala in Wales is a UFO hotspot and black triangular craft have been seen emerging from the lake.

Also, I was reading a book by some remote viewer named Ingo Swann, and he says he was taken to a lake where one of these black triangles emerged.

According to Swann he believes they are drones sent here by a civilisation from the dark side of the moon to collect water.

Could the triangular object in the vid be one of these drones collecting water?
