Bugs in Waterfall

[Mohr Family]

Hi All,

I am new to actually having a pond, but have experience of the aquatic nature ( so to speak ). We have a 2500 gallon pond with a sizable waterfall and powerful circulation. I have noticed thousands of insects that seem to attach to the rocks and slate of the waterfall in the current. I can't seem to find any in the pond. They seem to thrive anchored in the current. Does anybody know what they might be?

Sorry...forgot my name and such...

Can you describe these bugs a bit more or take a picture of these bugs?
