Salt surge river Bure.

Post by JohnS » September 22nd, 2018, 12:39 pm

Witnessed thousands of fish swimming into Acle dyke this morning, trying to escape the looming salt surge. Now seeing dead and dying fish ☹️ Even saw 2 dead pike and a jelly fish in the dyke. All very sad, shame we can’t have a salt barrier at Yarmouth. If you see any dead or dying fish, please report it to the Environment agency on 0800807060

It wouldn't work,
when they were researching the water Flows of the water coming down the Bure and From Breydon, they couldn't account for a large proportion of the water. It was eventually found that as GY was built on a gravel spit much of the water travels under the town...

I am a little confused here and excuse my ignorance but sometimes it is unavoidable.
What is a salt surge exactly?
Surely the water is brackish if anything, what would cause such high levels of salt that fish are dropping dead?....or floating up dead.

If you get the right combination of spring tides, wind and atmospheric conditions it can push the salt water further into the broads system, can stop the tide going out causing the next tide to be pushed further up, most winters salt water gets above potter bridge, the environment agency have sensors so they can raise a barrier at herbert woods to protect the thousands of fish that over winter in the boat yard!

Scardinus is right,
We have at the moment a northerly wind which pushes the water down the north sea so when it gets down here it rasies the level as the Channel at Dover is much narrower.
We also have a full moon so the highest spring tides are due Thursday raising the level on top of that.
We have had a series of low pressures going over also raising the water level.

We've had hot sunny weather for before then for a long time so the water level was low, and now it's rushing up river as a salt surge.
