Please explain these waves.

We have an impoundment with an artificial dam. We have a beaver problem. The beavers keep clogging the dam. The beavers never give up. Which gives me the opportunity to watch some interesting ripples or waves on the water. An underground pipe has a parallel to the ground surface opening under water. The water goes through the pipe, which actually has a slight angle to increase the throughput of the pipe. When the pipe is clear a whirlpool develops, and then there are other little whirlpools that circle the larger whirlpool, until they are caught by the larger whirlpool. At a distance, perhaps a meter, the line is about a meter and a half, from the main whirlpool, a line in the water develops. Past this line there are very fine ripples that go away from direction of the whirlpool. If a bug lands on the water by these ripples, it quickly gets carried over the ripples and towards the whirlpool, but seemed to be pulled very fast over the ripples.
Anyone have thoughts on what this phenomena is?

2. That's a complex system. My guess would be that you have longitudinal and transverse waves and the bugs are a "trick". The longitudinal waves are crests and toughs in the water which is side to side motion and also a in circle vertically. The other waves are up and down. The bug resting on the water races towards a point quickly because it's on the surface and not in the water. It doesn't interact the same way as the water because it has different forces on it. It picks up momentum in a direction from the water but because it isn't in the water, it doesn't get as much drag so it keeps gaining speed.

I guess he hangs six surfing?

4. Is it possible to show us a picture? Or better yet, video?

Thank you Solfe.
