Estuaries- River Finishes and Sea Starts?

[MARTYN]

Anyone Know Where the line is drawn for a River Finishing and the Sea starting ???

[gonzo00]

lol! are you fishing with no licence???! the line is usually drawn from point to point at the estuary..it is very common to have arguments of a physical nature with water ballifs over this subject whilst fishing for sea trout /salmon etc in ireland , as everyone has thier own opinion on where exactly the estuary is!! for instance..in galway city ,the river corrib ends at the harbour bridge but the line is drawn( by the fisheries people )about halfway up the pier,making it illegal to fish the inner half of the harbour..not fair in my opinion!

The River Thames is tidal as far asTeddington Lock, some 17 miles from Westminster Bridge. Strictly speaking, you could say that the estuary only ends where the river is no longer tidal , before that point it's sea.That's the explanation of the answer to an old trick question: " Is it true that Nelson can "see" the sea from the top of his column?" The answer is 'yes' as a man can see the sea from there, because he can see the Thames near Westminster Bridge!
Nothing to do with fishing, of course. The authorities set their own boundaries on their own rivers, without regard to such technicalities.

The river Trent is tidal to, I believe Cromwell weir, just a few miles from Newark, which would mean the Trent Estuary would stretch miles in land if you go with the tidal explanation. Just where a river ends and the sea begins is I'm afraid something the experts will have to decide, perhaps by the salinity of the water?

The subject is complicated because the dividing line for individual rivers can be set by authorities ranging from local councils up to ''by act of government'' level. In addition, there can be different limits for the same river, such as one for fishing and another for navigational requirements. The only way to find out is perhaps to ask your the local council.
