Groynes are often thought of as one end of a rock sill. Deflecting or repelling groynes are often used to push water away from severely eroding banks. Sediment often builds up between the groynes where a succession of grasses, bushes and eventually trees grow.  Groynes are often installed as part of a bank stabilization effort to further increase fish habitat while controlling stream flow direction and velocity.

The KWRC and our partners have provided the Kennebecasis Watershed with 54 groyne structures.


  1. Control flow direction and velocity on hardened stream banks to reduce risk of downstream erosion
  2. Increase fish habitat
  3. Improve stream channel stability
