Conwy/Dee Levels

Post by RichA »

Similar to the Dart thread in the SW forum, is it worth having a similar thread in this forum for main rivers in N. Wales?



Anyway, for anyone that is interested here is the level of the Conwy as of 7am today.

Image

As you can see it's on 1.0m. This relates to 1000 on the phone gauge.

2.0m on this graph relates to 2000 on the phone gauge.

Strangely enough, the graph and the phone correlate exactly, at least between 0.8m and 2.5m. Makes sense seeing as they both use the same gauging station!



It appears to work for the Dee too.

Base level of the Dee is about 0.6m, or 6000 on the phone.

11,000 on the phone gauge (Or x1,000 if you ignore the first '1' that everyone seems to count) equates to 1.1m on the graph.

12,000 equates to 1.2m.

Rich,

All good stuff, but I'm not sure how to equate this to what the level is like for boating. A quick search on the forum suggests that it should be at least 1100 to bother getting in your boat, are you able to elaborate?

Cheers
Martyn

For the Conwy, the Fairy Glen section runs from approx. 1200 - 1400 on the phone gauge, or 1.2m - 1.4m on the graph.

The A5 - Rhydlanfair section 'runs' from about 1200 upwards, but the higher the better.

I've not done the section above this that ends at the A5 bridge, but believe it needs higher water than for the section starting at the A5 bridge.


Phone----Graph----A5 Gauge

1000-----1.0m------Bottom
1500-----1.5m------3/4
3000-----3.0m------Top

Obviously all opinions are my own!



For the Dee I'm a little less certain as I very rarely paddle it. If you ring the number now (01978 710 398) and then compare it to the graph for the time you rang it, I'm sure you can work it out.

It is on (1)700 now which is low but paddleable - 4 or 5 at Mile End Mill as far as I can tell.

I'd hazard a guess that (1)600 is the lowest you'd want to paddle it, and anything above that would be better. I'd welcome suggestions for that though!

Possibly...

Phone-------Graph-------MEM Gauge
(1)500------- 0.5m-------- 2/3
(1)800------- 0.8m-------- 5/6
(1)1,000----- 1.0m-------- 9/10


For the Dee phone gauge there seems to be confusion over the level the phone says. It says "1 (pause) XXX(X)". People seem to take the first '1' into account which I think is wrong. It should read the same as the Conwy gauge.

For example,
"1 pause 500" would be 500 (0.5m), not 1,500.
"1 pause 900" would be 900 (0.9m), not 1,900.
"1 pause 1800" would be 1800 (1.8m), not 11,800

Fairly obvious when you think about it, otherwise the phone scale would go 1,800 1,900 11,000 11,100 which clearly doesn't work.

At 835 I wouldn't bother getting on if I where you, in my opinion, you need 1100/1200 to be worth getting on, we've had bright sunshine in Ruthin all day and no sign of rain yet this week.

Sorry your post has confused me slightly. The phone gauge gave a reading if (1) 835. So if you say that you recommend 1100 does this mean that I would be listening for (1) 1100?

Thanks

Looking at the graphs on fishing-visitwales you will see that most (but not all) have summer & winter average levels, winter mean is generally too low to be worth paddling, summer mean is definitely too low.
