EDIT: A new England and Wales calibrated river levels site is now available: Rainchasers
This has many calibrated gauges for the northeast.

To send in a tweet, simply start with #ukrgb, [river name] where river name can be Tees, Swale, Wharfe, Tyne, Wear, Coquet or Ure (e.g. #ukrgb, Tees). If anyone wants any others added please pm me. If you prefer just adding posts about the river levels please add these in this topic below.
All calibrations are subjective. Low means floatable, things may go at a scrape a bit lower. High means a good fast flow, all rocks covered - in some cases rivers will remain paddleable at much higher readings. Please contribute if you know better or can fill in any gaps.

River Wear Info
Stanhope gauge needs to be >1ft for the upper, with >2ft for starting at the waterfall. The phone gauge seems to correspond with this, but is in metric (0.35/0.7m respectively), but remember this is at ~3am, so the river level will have changed by the time you get there. The EA Stanhope gauge should be comparable.
Note the Fish Tyne live water levels. Also note the proposed Kielder releases.
North Tyne needs >1'8" at Reaverhill, Allen needs >1'4" at Bluebeck. Not sure on South Tyne, but probably >1'6".
