Oxford Slough Waterfowl Production Area is a slough in Franklin and Bannock counties on the edge of Oxford in southeast Idaho. It was purchased in 1985 from the Federal Land Bank using Federal Duck Stamp funds to protect redhead nesting habitat. The area is largely hardstem bulrush marsh, interspersed with open water and surrounded by areas of playa, saltgrass flats, native wet meadow, and some cropland. The lower areas have visible alkali deposits. The marsh is fed on the north and drained at the south by Deep Creek. A smaller creek and several springs feed the marsh from the west. It is managed by Bear Lake National Wildlife Refuge.
