EROSION CONTROL PRACTICES
Erosion control practices help reduce soil erosion, sedimentation and potential attached pollutants and consequently improve water quality.  The Lincoln SWCD has staff available to help you determine which practice best suites you needs and will help you with cost-share options and technical service.  Shown below are some erosion control practices that are important to the protection of water quality in Lincoln County.
Grassed Waterway: A natural drainage way is graded and shaped to form a smooth, bowl-shaped channel.  This area is seeded to sod-forming grasses.  Runoff water that flows down the drainage way flows across the grass rather than tearing away soil and forming a larger gully.  An outlet is often installed at the base of the drainage way to stabilize the waterway and prevent a new gully from forming.

Water and Sediment Control Basin(s): An embankment is built across a depression area of concentrated water runoff to act similar to a terrace.  It traps sediment and water running off farmland above the structure, preventing it from reaching farmland below.

Field Windbreak/Living Snow fence: Windbreaks are rows of vegetation used to reduce and redirect wind.  Field windbreaks reduce wind erosion, improve crop yields and water use efficiency.  Living snow fences keep roads clear of drifting snow and increase driving safety.  Vegetation and plant debris slow surface runoff and encourage sediment and sediment-bound contaminants to settle before entering surface water.  The leaves and branches intercept rainfall, reducing their erosive energy and slowing the movement of rain water.  Root growth and plant litter improve soil structure and enhance infiltration of rainfall, reducing surface runoff.
