What can we expect once the thaw sets in? All this salt on our roads has to go somewhere & I suspect it will end up in our rivers and lakes. Will mother nature cope with this or shall we see reduced invertebrate & fish stocks?
Can anyone out there put my fears to rest?
Rod.

Rod, I was thinking the exact same thing but was too scared to know the answer

Relax. The salt is diluted so much by the ice and snow that it lies on, that's why it needs to be reapplied. I seriously doubt it could affect the watercourse.

Won,t harm the fish as many of the species can live in salt water (sea) happily,
not sure about plant life or things like water snails.

It doesn't have an impact. The roads here in Minnesota are salted far more and far longer than anything the UK would see. The first snow and salting here is in November and from there it's constant roadsalt until April. If salt caused any problems with water quality, we'd have seen it decades ago.

Good point MM - it's insects and invertebrates that teeter on the edge.


"Stuart 'I'm all right Jack' Pengs" - I'm rather suprised at that response. The Conwy system has main roads all along every one of its arteries.


Hopefully my thriving 'Iron Blues', much endangered elsewhere, will come through unscathed. The cash strapped council, having banked and lost £ millions in Iceland (sic.), are refusing to 'grit' the road despite it being a designated bus route. The buses and the treasurer slither on...

Eh? I'm not saying it hasn't Ephemerella. What I am saying is gritting the roads doesn't appear to affect the watercourse. If you have evidence to the contrary then please share. How is that a "I'm alright jack" attitude, if it does affect the watercourse, it would be fair to say I'm certainly not 'alright Jack'.

I apologise for the 'I'm allright Jack' remark if you're stung; or I'll rub more salt in if you persist in stating that road wash and grit don't affect the Conway river system.

I will say it's probably worse for Warren's limestone spring streams, and Wye river adjacent to the A6, suggest you search his more authoratative posts on this subject.

The A5 flows beside the Conwy..

Where is your evidence Ephemerella? I'm genuinely interested. If you are alluding to diffuse pollution then yes I'm perfectly aware of its effects on watercourses, but do you have something specific regarding road salt and the Conwy?

Oh, BTW, please don't refer to it as the Conway, anything but that.

I will just add after Iv had tine to think this through! that on the lower stretches of the river Camel which are tidal, so get a good dose of salt every 12 or so hours, have a very varied selection of fly hatches and invertebrates, but this may be because they are specific to saltier water areas.
I must say this is very interesting and needs more research.
Good stuff rod3
