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 />
