It might be time to rethink the future of Crystal Lake. Pumping is not a long-term solution and, after about 15 years of rising water levels, maybe its time to accept that the water table in the area is fundamentally and irreversibly changed.
Devils Lake in ND has had similar issues. For those on the lake my hope is that there would be federal or state support to allow them to move out. Very difficult situation to be sure.
