Primary damage is gully and sheet <br /> erosion to cuI tivated land. Farmsteads damaged in 1951 flood have been <br /> moved from flood plains. Many damaged bridges have been replaced by low <br /> water concrete slabs. Of 802,592 acres in tillage rotation, about <br /> IS7,40D acres have gully and sheet erosion problems. <br />Institutional Issues: <br />50.
