Last one for now - Again the upper Tees - Tomorrow I will post some of the Lower Tees.
For a map of the area see
the river is navigable to just upstream of Yarm.
At the location marked on the map (zoom in) is the Tees Barrage - have a look at this site - lots of pictures of the Tees.
The Barrage splits the river into a tidal, and non tidal river at this point. Down towards the mouth of Tees it gets very industrialised and busy with Bulk Tanker ships See the Tees and Harlepool Port Authority site for info
just had a look - good maps of the river.
So as you can see a very varied and interesting River.
ps - Yes there is a speed limit of 7MPH on the upper Tees - but the NRA was exempt from that Bye-Law
