The first pic is of a large tractor and a large excavating machine that are building a road down the middle of the lake past the lake side of our house. The road will head over to Spring Brook where they plan to do some serious dredging since the "spring" or small creek has brought in a lot of silt. They also have to finish some connections on some of the sewer pipes.
The second pic is of a "bubbler." I bet very few people have seen a bubbler of this size. For those who haven't been been on the lake in the summer, there area many bubblers sprinkled around the lake (submerged of course !) that help improve the oxygen quality and help prevent algae growth.
