Hog-Creek Marsh, comprising 8,000 acres of Brookston-Crosby soils, is named for Hog Creek, which drains it. Once a shallow lake, it supported cranberries, wild flags, and grasses. Reclamation in 1868 cost $13.00 per acre. Dredging was done by steam scow, and lateral ditches were dug by hand with spades. The original grade of 1/3 inch in 100 feet proved ineffective for onion, beets, and potatoes. In 1949, restored drainage outlets gave new life to the area for soybean and corn agriculture.
