Every 12 hours the water level oscillates between high tide and low tide, but the pattern of tidal waves is surprisingly complex. |
Sometimes on an exceptionally high tide the water flows over the weir causing a tidal effect as far up as Kingston. |
At high tide it is fully submerged, but at low tide the tip of the ceiling is just dry and can be seen from a boat. |
At low tide the river level can be 15 feet or more lower than at high tide. |
The fishing behind the boxes has slowed down considerably due to the havoc caused by the seals that come into the Ridge Pool with the high tide. |
I've been to mud flats where there's a six-foot difference between high tide and low tide. |
