The River Lea is so little known that Griff Rhys Jones had to begin and end his River Lea episode tonight by the Millennium Bridge spanning the Thames.

I enjoyed the programme although I kept wanting to reach for  a map every time he jumped ahead on the north-south route. The presenter covered several interesting aspects.

He made a good point about the name Luton being partly derived from ‘Lea’.  There should have been more about the town and the charm of the River Lea’s first few miles. But it’s the London end that has more resonance to the viewer watching for just an hour.

Of course in three year’s time everyone will know about the River Lea.

If you missed it you can watch on BBC iPlayer.
