Pond Boss Forums POND CONSTRUCTION Creating habitat Pushed shrubs into pond

I bushhogged the back side of my pond. I had not cut it in over a year. There were small trees and bushes that had grown up. Instead of pulling them up, I decided to push them into the water. My pond has no shelter for small fry. I pushed them in yesterday and today I saw swirls around them. Is there any reason not to do this? If so I can drag them out with my tractor.
