I thought it best to post this as a new thread since the one that it came up on was already off-topic.
Palmtree kindly took a set of three photos of the gauges at Potter bridge yesterday morning to enable their differing readings to be compared.
I've created a composite of the three gauges, (upstream, downstream, and pilot office), and added the daily graph from the EA flood gauge at Repps, about half a mile downstream.
That graph is uploaded to the Internet each morning at 04:30 to http://www.environment-agency.gov.uk/homeandleisure/floods/riverlevels/riverstation.aspx?StationId=6217&RegionId=1&AreaId=2&CatchmentId=5
This means that anyone interested in knowing how the clearance is going at Potter can check what the onsite gauges were showing the previous day by applying the conversion factors.

That's very useful, Strowager. Thank you for your efforts.
Using your formula, I now know I want 0.3 on the EA gauge, as I need 6'8" if the pilot's taking me through (a teensy weeny bit more if I'm piloting myself, 'cos I'm a wimp!).

Hi,
Nice job on the calculator, just one thing the level indicator in the office is it showing 5'10" or 5'8"?

You gave me quite a sinking feeling there Ian. 
The Pilot's office gauge appears to be graduated in one inch increments, with a broader dash every three inches, and a number every foot.
The numbers increment downwards, because the lower the float the higher the air clearance number.
The pointer is on the second division above six, hence the five foot ten inch reading.
(and I'm very relieved that I'd got it right !  )

Hi,
Sorry for the panic, now I can see the full scale it makes sense!

Thanks Richard, it should now enable anyone to satisfy their own curiosity of how the air clearance is doing at Potter.
A great idea of Palmtree to take that set of photos.

Hi everyone,
Quick question to find out what the water levels are like in horning and potter heigham area? We are in cambridgeshire and with the high rainfall our rivers have escaped their banks!
We are hoping to move our yacht from ferry marina to its new berth at hickling this friday and wanted a bit of insight in to how levels are there, will save us a journey if potter bridge not "dooable!"
Thanks
Matt

I think I am right in saying that if you look at the photo attached to the first post in this thread, you use the calculations from the Environment Agency's water level gauge (web link in first post also) and by applying the formula get the river level at Potter Heigham Bridge - meaning you need not be at Potter Heigham or see the gauge at the bridge/pilots office to get an idea of the air draft.
