Really neat!
I don't think the image quality is so bad, and it's really cool to see the egg mass.

Yes...
this looks like Ephemerella invaria. Their method of oviposition is known as "bombing"--they release the entire egg mass from the air or sometimes by momentarily contacting the surface of the water.
