Basin is not — <br /> hydrologically connected to any waters of the U.S.and is likely to be considered"isolated"from navigable waters vis-a-vis the <br /> SWANCC decision. In addition,wetland hydrology is formed only through artificial irrigation and the feature would revert to uplands <br /> if the irrigation ceased.The soil series mapped for the area are upland soils. — <br />
