serious problem. <br /> • Clear accumulated trash away from water control infrastructure,including pipe inlets,rock riprap, <br /> and vegetated spillways. <br /> • Inspect valves for proper functioning.Guards must remain in place to keep structures operating as <br /> planned. Promptly repair or replace damaged or inoperable components. <br /> • Repair any settlement or erosion that occurs along the pipe. If this problem persists,evaluate the <br /> pipe for leakage and erosion of the fill material into or along the pipe. <br /> • Fill rills and gullies that occur on embankments and in the vegetated spillway. Reseed the filled <br /> areas. Repair erosion at pipe outlets promptly. <br /> • Eradicate or otherwise remove all rodents or burrowing animals from any embankments. <br /> Immediately repair any damage caused by their activity. <br /> • Protect the structure from damage by farm equipment and livestock. Repair or replace damaged <br /> fences to keep livestock out of wetland,where applicable. <br /> • Maintain vigorous growth of desirable vegetative coverings on the embankment.This includes <br /> reseeding,fertilization,and mowing as needed.Time the first mowing after August 1 when most <br /> ground nesting birds have finished nesting. When applying fertilizer to vegetative cover,use <br /> caution to prevent degradation to water quality. <br /> • Prevent woody vegetation from growing on or around the embankment,abutment,or vegetated <br /> spillway areas. Control tree and bush growth by hand cutting,mowing,or chemicals. Avoid <br /> damaging grass or aquatic vegetation with herbicide sprays. <br /> • Maintain a vegetated buffer around the perimeter of the wetland to trap sediment. Follow the <br /> operation and maintenance instructions for the buffer. <br /> Structure Summary <br /> Elevation,ft Boards in Control Structure(maximum) <br /> Structure ID Top of Box Highest Board Level Height,ft Number of Boards <br /> NRCS, IL ODM-Page 2 of 3 May 2013 <br />
