Maintenance and inspection of fish ladders

Maintenance and inspection of fish ladders

We like to take over the maintenance and inspection of your fish pass. In the course of maintenance, the following is carried out:
  • Flow measurement in the fish ladder
  • Examination of pool raids with regard to the notification requirements
  • Examination of the water depth in the fish ladder in relation to the notification requirements
  • Check for clauses of the entire fish ladder and also their removal, if possible by hand
  • Examine the bottom substrate for rinsing
  • Checking boarding and alighting in relation to silting
  • Reporting
  The maintenance of the fish ladder should be carried out before the fish migration and after flood events in order to ensure the functionality of the fish ladder for 300 days a year, as required by the authority for fish ladders.
