The Mason Esker and associated loamy sand and sandy loam soil areas are the major ground water recharge areas for Ingham County residents.
Eskers are the predominant geologic feature near the stream.
These grade into moraines that are approximately one-half to one mile in width. The moraines grade into till plains. Interspersed within the area, in depressional areas and drainageways, are organic soils. Major BMP'S already implemented in the project area are pasture and hayland planting, pasture and hayland management, diversions, cover and green manure crops, critical area plantings, conservation tillage, grade stabilization structures, grassed waterways, and integrated crop management. 1990 Crop and residue cover are recorded on a 10-acre cell basis in each of the three monitored subwatersheds.
