The surface soil profile of this area is Coffeen silt loam, 0 to 2 percent slopes, that are frequently flooded. The Coffeen series consists of very deep, somewhat poorly drained, moderately permeable soils on flood plains, low terraces or benches, toe slopes, and alluvial fans. They formed in silty alluvium. Much of the alluvium is of local origin derived from the nearby loess-covered uplands.
