This survey updates an incomplete farm tract soil mapping project for Otter Tail County. It includes mapping of previously unmapped areas and updates the interpretations for the soil types in the county. Soil scientists were denied access to a few tracts in the county. These areas are indicated by a dashed line around the tract. Soil scientists mapped these areas using knowledge from the surrounding areas, older soil maps, and photo interpretation of aerial photographs. The descriptions and map unit delineations of the soils on these tracts may be less accurate than those in areas where the soil scientists had access and could carefully examine the soils.
