Yup  -  water level really low, so loads of bridge clearance.

On Sunday evening, more than half way from low to high tide, there was 6ft 9in.

Looking at the Repps gauge for today (Fri), there was 7ft at 0400 (and presumably at 4pm as well).

But also means that some of the normally-navigable rivers are a bit shallower than they might be sometimes.  -  like I went really firmly aground on Hickling on Sunday.

I recently compiled a chart to get a rough idea of clearances at Potter Heigham Bridge.

Using B.A tide information I look for dates that high or low water occurs near 00:30 Hours at Gorleston (Yarmouth Bar) adding on four hours for high and low water at Potter Heigham makes the time 04:30 Hours which is the time that the Environment Agency tend to record the river level at Repps.

I then use Strowager’s formula to work out the Bridge clearance.

This is what I have done so far.

16 February 2015 – 9 mins before Low Water 7ft 1in (0.18 at Reps)
24 February 2015 – High Water 6ft 1in (0.48 at Reps)
01 March 2015 – 29 mins before Low Water 6ft 8in (0.30 at Reps)
12 March 2015 – 6 mins before High Water 6ft 9in (0.28 at Reps)
18 March 2015 – 25 mins after Low Water 7ft 2in (0.14 at Reps)

I hope I’ve done it right. Question

Wouldn’t it be good if there was a permanent webcam to The Pilot’s gauge?


Kind Regards

We went up to check the boat on Saturday and it was firmly stuck in the cutting! Very low... Good job I wasn't planning a sail in a hurry!

Thanks for a very useful thread. Richard, the link to the Repps gauge in your sticky posted back in 2013 is now superseded. Here's the current one:

With all these measurements flying about, can anyone tell me how the measurements are taken....
I know the water surface is where the measurement is taken from... LOL

Where is the second on an ARCHED bridge?... As I don't know of any boats with an arched top, matching the profile of the bridge's stone work...

just to let you know we actually managed to get through the bridge on OCT 8th we were on Southern Horizon height 6ft6 the pilot got ud through even though the clearance was just showing slightly over that height we were almost alone very few boats therefor 4 nights cane back through 12th low water was at 430 but we got through no problem at 1240 it was a neep tide and the young pilot was taking boats through ar 6ft7 or less

I'm informed that the bridge height displayed in the Pilots office is taken from a width of 6 foot and the marker by the bridge has been hit by boats so many times its not to be relied upon...
