The table has data for all tides, ebb and flood, colour coded for how exciting/hairy/spectacular they are going to be.
This means that the table is vast, however we do it like this so that sea kayakers, canoeists, sailors and anglers as well as play-boaters can search the table and see dates that will suit their purposes.
This might make it harder work for play boaters to find the info they need – sorry! Just look for the red and black boxes.
The graph is a visual indication of what the tide height is doing, along with when the falls will be running and how good they might be. Click the buttons for information about the ebb and flood tides, the lighter bar indicates the start of the flow and the darker portion the best times.
For the Ebb tide the height of the coloured bars indicate the tidal range, for Flood tides they indicate the height.
