The fish ladder:
Fish ladder is provided, for the following purposes

  1. For movement of fish (serves as the artificial barrier in either direction)
  2. Difference of level on the upstream and downstream sides on the weir is split up into water steps by means of baffle walls constructed across the inclined chute of fish ladder.
  3. Velocity in chute must not be more than 3m/s
  4. Grooved gate at upstream and downstream - for effective control.
  5. Optimum velocity in fish ladder is 6-8 ft/s
