This is from the lake near by where I live and it is possible to walk on already around the edges but, I am not so game to take my camera swimming so didn't venture out. After the next cold snap, it should be enough.
The lake you live next to is a big lake and there could be rifts in the middle. You are wise not to go to the middle, yet.
Yeah, I am not like one of those crazy fisherman in the Spring.
