I saw the dive but I didn’t see the Osprey go into the pond to catch this fish as my view was blocked by a tree. Osprey can completely submerge and work really hard to break free of the water, harder if they caught something. Other times I have witnessed this the Osprey would then make a bee-line for a tree or other secure spot to eat.
Back in my line of sight he shook several times, lightening his load of the excess water while hanging firmly onto lunch. Then he circled around the pond several times with his catch, undecided about where to go.
What he probably knew that I didn’t until a couple minutes later was he was about to be chased by a pair of Bald Eagles hoping to lighten his load. Suddenly he decided to head for the trees and the last I saw of them the Osprey was in the lead.
