The soils within the watershed are predominately Fox and Miami loams in the upper portion, with Morley and Blount in greater proportion downstream. The slopes on Wold Creek Watershed vary from moderate to steep, with an average allowable soil loss of 3 tons per acre per year. Moreover, the recent National Resources Inventory for Lenawee County indicates that 10,000 acres in the watershed have an average soil loss of two times the allowable, with an additional 2,500 acres exceeding 12 tons per acre per year. The topography within the watershed varies from the northern portion to the south as it drains into Lake Adrian. The northern portion of the watershed is very steep, with irregular slopes located throughout the fields.
Natural drainage is good to excellent, with small wet basins located throughout the area.
The southern portion of the watershed is more gently rolling, with slopes becoming more regular. Natural drainage is moderate to somewhat poorly drained and topographically, lends itself to be intensively farmed. The upper portion drains through Loch Erin, which serves as a wildlife area and is in the process of being developed for home sites. There is heavy recreational use of waters in this watershed. This includes pleasure boating, swimming, and sport fishing.
