Comprising 8,000 acres of Brookston-Crosby soils, the marsh is named for Hog Creek which drains it. Once a shallow lake, cranberries, wild flags, and grasses flourished here. Reclamation (1868) cost $13.00 per acre. Dredging was done by steam scow; lateral ditches were hand dug by spade. The original grade of 1/3″ in 100′ proved ineffective for onion, beets, and potatoes. In 1949 restored drainage outlets breathed new life into today’s soybean and corn agriculture.
