ATS Fish Friendly Flap Gates have an adjustable offset top hinge-point that allows a variable delay in the closing of the flap.
Fish have a greater opportunity to migrate upstream.
Upstream water quality is usually improved with greater tidal flushing.
The flap still closes once the water level reaches a certain level.
