Groynes

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.

Benefits:

  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
