These are pictures from the Devils Lake job in ND where Tri-State Diving was hired to remove high line poles from the Lake. Over the past ten years Devils Lake has risen over 25 feet and therefore a lot of real-estate has become part of the lake. Subdivisions have had to be removed and all the houses and other buildings either torn down or moved to higher ground. Minnkota power company hired us to remove all their power poles that were out in the lake. We spent 4 days over two trips cutting the poles off underwater using our hydraulic chain saw.
