people are aware of the mighty Severn Bore, but few people are aware
that many other rivers in the UK also have their own tidal waves rolling
upstream. In comparison to the wall of water which hammers up the Severn
during high spring tides, the bores on many other UK rivers are much
smaller. However, when witnessed in person, they're an astonishing spectacle
that need to be seen to be believed. One of the largest tidal bores
in the UK, after the Severn, occurs on the river Dee, on the Flintshire-Cheshire
border. Straddling both England and Wales, the Dee Estuary narrows rapidly
into the straight, man-made channel of the lower Dee. The tidal section
of the River Dee is approximately 16km, from the Dee Estuary, to a large
weir in the centre of Chester (although at very high tides, salt water
can overrun the weir and continue upstream). The Dee Bore itself, however,
can not travel further than the weir. In fact, by the time it reaches
the city of Chester, the bore resembles nothing more than a small heave
in the water surface.
really appreciate the bore as a relentless wall of water, you need to
witness it somewhere between the Dee Estuary, and the main river bend
at Saltney, where the man-made channel reverts to the original river
configuration. There are many viewing locations, which essentially can
be anywhere along the channel, as public footpaths line its entire length.
However, there are two very popular viewing locations, both of which
have been highlighted on the map below.
