Fish Friendly Flood Gates

Another one of Hamish's projects is to oversee the installation of Fish Friendly Flood Gates (FFGs).

These gates close slowly during flooding or tidal movements to allow fish easy passage upstream.  This gate has been installed just outside of Te Puke.

There is a lot of science involved in these gates...
Water flow
Tidal effects
Fish monitoring

Just the right amount of weight is required to make them work properly.
Hamish is doing a bucket test to work out how much more weight is needed on this gate installation.
