Preble Soil and Water Conservation District

Pond Soils:

Soils ultimately determine whether a pond holds water or if it leaks.  Soil surveys can provide useful information to evaluate soils, however, knowledge of the soil profile to a much greater depth is necessary.  Test holes should be dug in the pond reservoir and embankment areas to a depth of 2' below the proposed bottom level of the pond.  Sand or gravel encountered while digging test holes may indicate soils that are not suitable for a pond or that will require a major expenditure to overcome the limitations.  Ideally you will encounter soils with a high clay content that compact well.  Those type of soils provide a good seal and usually result in a pond that does not leak.
