Gulls Out, Geese In

Today seems to have been the turn of the Canada Geese to occupy the structure in the lake from yesterday's blip.
The lake was built as a boating lake, I believe that this structure keeps the boats away from the inlet where the River Lea enters the lake, there is a similar structure at the other end of the lake which would prevent boats from exiting into the River Lea as it exits the lake.
Nowadays the only boats on the lake are model ones from the local model boating club.
