  • Kent Wamsley standing in a traditional ditch in Howard County. Note the bank failure.
  • Same agricultural field, but now with a Two-Stage Ditch.  Benches have been created and the bank side slope is stable.
  • Diagram of a conventional ditch.  The conventional ditch provides less area for incoming runoff to spread potentially creating more chances for overflow, flooding, and soil erosion.
  • Diagram of a Two-Stage Ditch.  The Two-Stage Ditch provides more surface area for runoff to spread, thus reducing the water levels in the ditch. 
  • The eroded soil and deep banks of this conventional ditch decreases drainage of water runoff
  • By leveling the banks of conventional ditches to 2-3 ft above the bottom for a width of 10 feet on each side, the Two-Stage Ditch increases area for water to spread.  This, in turn, slows the velocity of water runoff. 
  • Nature attempts to scour and slough banks to form benches in a conventional ditch.
  • Seeding can be done by drills, spreaders, blown on, or on small projects done by hand.
  • After the installation of a two-stage ditch
  • Making of a two-stage ditch
  • Two-Stage Ditch during construction
  • The wide and shallow banks of a Two-Stage Ditch prevents overflows of water following a storm event.
  • Two-Stage Ditches could relieve the erosion, scouring and flooding that conventional ditches may cause.
