Low runoff potential. Soils having high infiltration rates,even when thoroughly <br /> wetted,and consisting chiefly of deep,well-to-excessively drained sands or <br /> gravels. These soils have a high rate of water transmission. <br /> B. Moderately low runoff potential. Soils having moderate infiltration rates when <br /> thoroughly wetted,and consisting chiefly of moderately fine to moderately <br /> coarse textures. These soils have a moderate rate of water transmission. <br /> C. Moderately high runoff potential. Soils having slow infiltration rates when <br /> thoroughly wetted,and consisting chiefly of soils with a layer that impedes <br /> downward movement of water or soils with moderately fine to fine textures. <br /> These soils have a slow rate of water transmission. <br /> D. High runoff potential. Soils having very slow infiltration rates when thoroughly <br /> wetted and consisting chiefly of clay soils with a high swelling potential,soils <br /> with a permanent high water table,soils with a hardpan or clay layer at or near <br /> the surface,and shallow soils over nearly impervious material. These soils <br /> have a very slow rate of water transmission. <br /> 1-5-32 <br />
