Hi Buds - The lakes are getting warmer. Just 6 years ago the average temp in January (the coldest period) was 5c, now its 7 to 8c. For June it should be between 7 and 8c but its actually at 12c right now. Thats a big change.

If you have dived the lake district between Jan 2005 and now - would you please check your logs and PM me with the following details: Date(s), Lake(s) Dived, the Site(s), depth reached and temperature details.

I'll be compiling this data into a spread sheet in order to create a more accurate and up-to-date charts for everyone on my Freshwaterdiver.com website which hopefully will be completed for Jan 2008.

What effect these higher temps may have on the aquatic ecology of the lakes - I hate to think.

Sincere thanks to all those who may wish to help.
Yours - Webmaster Paul

Paul,

I'll trawl through my logs and send you some data. Do you have a preferred format for the data or even a blank Spreadsheet to fill in?

Sheet format

Paul,

Alistair
I kept away from formats because I knew this would involve a lot of work for many of you - I did forget to mention "date" but have corrected that now.

So please just use your own format to make life easy for all concerned and I'll sort all the data out on my own end.

A Big thanks to all - in this 1st hour!

Alarming rise in Lake Temperatures

Hi Buds - The lakes are getting warmer. Just 6 years ago the average temp in January (the coldest period) was 5c, now its 7 to 8c. For June it should be between 7 and 8c but its actually at 12c right now. Thats a big change.

At least 1600 readings are required, so please help if you can
Sincere thanks to all those who may wish to help.

Does any info from Stoney, Gildy etc count? :)

Oh no, if the water gets too warm then divers will start wearing wet suits and will be peeing everywhere in the water!

I new my FFM was a good investment!

whats the temp in wasswater at the minute ?
Dont know for sure but if its anything like Crummock at the moment, its going to be about 12degC from 0 - 20mtrs and then dropping to about 6/8degC there after. The thomocline is very noticable in Crummock at the 20mtr mark right now.

I thought Wastwater and Crummock practically had no life in them anyway, I've only ever seen a fish as big as a stickleback in Wastwater before, but I bet there's tons of bugs 'n' things!!

Hi Finless - someone else may want to start doing Stoney etc but I've got my work cut out doing the lake District :rain:

Alway's wanted to try the fly zip in the lakes but it USED to be too cold for it :):)

Hi Freshwaterdiver,
I have seen some quite large (upto 1 metre) eels in Wastwater and also plenty of trout especially at this time of year,
i have lots of data on the lake temp but will need a bit of time to sort it out
What depth are you doing your study at or will it take this into account?

If anyone wants a dive in Wastwater tomorrow I am free and buddyless

hope this helps
winter 2006/7 not much snow on fells, so temp not lowered in march when any snow should start to melt, which would normally cause lake temp to drop as in 2005/6.
In winter 2004/5 temp was as low as 3C in Wastwater

Lots of Perch in Crummock water this year

5/9/2006 river flowing into head of wastwater was in full spate, bringing quite cold water with it, wild night dive with quite a lot of trout about and big waves for a British lake!

I dived Watwater some years ago in the winter time and watched a fantastic wall of halestones pass over us, thankfully we were out of the water and having our elevenses. We watched it start at one end of the lake then just before it got to us we sheltered in our cars, watched it pass over, then got out again to see it travel the rest of the lakes length.
Most fantastic thing to see that time of the year and sunshine either side to boot.

Surely without data going back over a few hundred years this will give a snapshot view only. What were the temperatures during the mini ice age, what about during roman times when vineyards were common in Britain. If you are looking for evidence of global warming/envornmental impact (as I suspect you are) then any conclusions drawn will be seriously flawed.

I think that the main variations are caused by water flowing into the lake, so if it is melt water from snow and ice this cools the lake much more than a period of cold weather with little snow. This is the type of weather we have had for the last few years. The base temp at 50 metres only seems to fluctuate between 5 C and 9 C. This is also due to the currents in the lake, prevailing wind from West drives surface water up the lake but when it reaches the top end the current changes direction and circulates back down the lake inbetween 25 and 10 metres depth ( there is a German sounding name for this but I can't recall it - considered making it up but some smart arse would correct me!) the water below 25 metres is relatively still with better vis.

I wish to thank the following buds "Lake Diver" and "Scuba Clogger", for their part in helping me (Webmaster for freshwaterdiver) with the water temperature readings in the lakes - in particular, Wastwater.
Both these two buds dive Wastwater every week but on different days. Hope you get to meet up sometime :)

I still have a long way to go and need as many readings between January 2005 and the end of December 2007.

Lots of fascinating facts are coming out of this:- If you are wanting to cool down by 4 degrees or so in summer, then dive near a river entering the lake. Wastwater is a good example where Lingmell Beck flows in and consequently dropping the temp by 4 degrees.

If you are diving in the middle of winter and are looking for a warm 2 or 3 degrees above the norm then try a dive Crummock water.

Coniston is proving to have hot and cold dive spots - still need more readings from anyone wishing to help.
Other key lake readings required are from Crummock, Coniston and Ullswater.
