I know there was a passenger service up until the mid-90s between Sunderland and Fatfield Bridge on the wear. 

The Tees is fine up to Yarm off memory. Obviously you've got the barage to navigate.

Close. Ryton Willows is as far as (shallow hulled) boats can go up the Tyne. After that it gets quite shallow, and Wylam is quite rocky
