Two observations fro me..
Firstly, its not actually a BOATING lake is it? In my day a boating lake was a very large expanse of water, (such as Peasholm Park in Scarborough) where you could row boats, or paddle canoes. This is just a shallow area for model boats.
Secondly, I was at West Shore tonight, and the 'boating' lake is so badly silted up that the swans have a large beach if they want to use it.
In fact the walkway along the sea wall is so badly covered with colossal drifts of sand that the steps are all hidden, and it is nigh on impassable in parts.
Its going to cost a lot of money and time to clear all that!
