I watched this Sub-Adult Bald Eagle go into the water for fish without success. In the low light of a cloudy overcast day with intermittent rain, I thought this was a wet Adult Bald Eagle. It is instead a Sub-Adult or Third Year Eagle. The Sub-Adult is in the transition phase to its Adult plumage of a white head and tail. Third-year or Sub-Adult Eagles have a dark patch below and through the eye and their head and tail still, have brown streaks. The Bald Eagle in the fourth year has the white head and tail of adulthood.
