Grade Stabilization Structure

How it works

This practice is short earthen dam built across a drainage way where a terrace is impractical. Water & sediment control basins can be used singly to help control the stability of an outlet or in series, both trapping sediment and water running off farmland. The uncontrolled drainage area into the basin must not exceed 20 acres and have a total drainage area of 50 acres or less.

How it helps

  • Basins improve water quality by trapping sediment upland and preventing it from reaching water bodies.
  • Structures reduce gully erosion by controlling water flow within a drainage area.
  • Grass cover may provide a habitat for wildlife.
