Slaughter Slough

Slaughter Slough is a wetland in southwestern Minnesota, United States, so named for being the site of the Lake Shetek Massacre during the Dakota War of 1862. It is located in Murray County east of Lake Shetek. On August 20, 1862, about 40 Dakota people attacked the area's Euro-American settlers, killing 15 and taking a dozen women and children captive. 21 settlers escaped or survived the attack and made difficult journeys across the prairie to safety. A band of pacifist Lakota later ransomed the eight surviving captives, who were reunited with their families.

Today the site is managed by the U.S. Fish and Wildlife Service as Slaughter Slough Waterfowl Production Area, a component of the Windom Wetland Management District. It is developed with interpretive signage, a short trail, and a memorial.
