Somerset Center (and the Railroad Bridge Buried Under the Lake) Dang – how many 'Somersets' do we need down there in Hillsdale County? 'Somerset P.O.' was the original name of just plain 'Somerset', and, out of all the others listed above, the one that doesn't exist any more is 'Somerset Station'. It was a railroad stop that is now buried under the waters of Lake Somerset. Lake Somerset is a man-made lake that didn't exist until 1966. The now-defunct American Central Development bought up the land surrounding Somerset Station, dammed up Goose Creek, and tore down the trees. Then they demolished the railroad depot, schoolhouse, and surrounding homes. Following this, they excavated a 27-foot deep valley and unblocked the dam, which allowed water to flow into the pit....and Lake Somerset was born.
