I was using this tool...


... to check on the size of a couple of waters we were considering for a club outing.

And then I measured a few of the waters I am familiar with and fish regularly - just for comparison. Then I added in some of the ones I used to fish to see how they compared. And I ended up putting in most of them. Then I added some of the ones I have never fished, but have read about and heard about... to see how they compared. The more I added, the more it became interesting to see which ones were bigger or smaller than which others. Some are bigger than I think they are, and some seem smaller - though a lot depends on whether they are roughly circular, or consist of all arms and legs. The circular ones pack in so many more acres than the leggy ones. Finally, I put in a couple of the big Irish loughs, which fairly put things in perspective!

Here is the current list...

(Sorry about the full justification - I can't find any way to narrow the columns???

LochLomond17500

LoughCorrib42000

I have to come clean and say that I did not attempt to measure Lomond, largely due to the islands. (I looked it up.) I subtracted the area of islands from the water surface areas in my measurements. I did measure Corrib, roughly 😜 , but the islands were way too much and I just made an allowance for them!

It really puts things in perspective when you can add up Lochs Awe, Ness and Lomond and the combined acreage is less than Corrib!

The 4 Cape Wrath lochs make a set (which was why the tiny 9 acre Lanlish makes the list. The 3, interconnected Badanloch lochs also make a set. And they brought up another point of interest - how many waters that lie close to each other are very similar in size. The other 2 lochs in that chain, Nan Clar and Rimsdale differ by 2 acres. And then you have Swannay and Boardhouse on Orkney, which lie side-by side and differ by 5 acres! See also, Arkaig/Lochy, Trawsfynydd/Vyrnwy, et al.

You can get a feel for the size of water you like to fish, I think. To some extent, I am a case of, "the bigger, the better". I like nothing more than to go out on a properly big water, such as Shin or Shiel, to explore what there is to be found. But at the same time, when I look through the list, I see many of my favourite waters falling in the range 300 to 600 acres. So, there is a question there for you - what range of size do you prefer to fish?

The list is obviously by no means exhausted or intended to be exclusive. If anyone would like their favourite water added to the list that doesn't currently appear, just ping it to me and I will add it in. I would make one stipulation... nothing under 20 acres, please. There are 1000s of such that could be included, and really the aim was to have a look at the comparative sizes of the bigger waters we have available to us.

That’s a great exercise Col and makes very interesting reading
Thanks very much
For me it begs the question as to what percentage of the Loch is worth fishing
Taking a couple that I am familiar with ,Fada at 69 acres can be fished over whereas Hope at 1527 acres is by and large only worth fishing in a narrow margin around the shore, maybe 5-10% of the total surface area
Would it be fair to say therefore that there could be more fishing to be had on Fada than on Hope which is 20 times it’s size
It would be interesting to repeat the exercise taking a line at the 20’ contour
Not at all suggesting that though and thanks again for some great work

That's a really useful tool, and I've checked a few of my favourite lakes and its certainly accurate even picking points around the perimeter with my forefinger on my phone. It'll certainly be very accurate when I try it out on a few more lakes that I don't know the area on my laptop tomorrow.

Any excuse not to work. 😁

Aye - for sure, Martin, a whole other chapter comes into play when you consider what percentage of the surface area (what I have quoted) is worth fishing. I think if you add up the fish-catching areas on Hope - top end, middle bay and south end combined - it will come to at least 2 or 3 hundred acres in total. :unsure:

Obviously, it depends on the bottom contours. The percentage of a glacial loch such as Loch Shiel that is worth fishing will be small, compared to the likes of Loch Leven. Back in the day, there was very little of Loch Leven's 3361 acres that was not worth fishing (at times), including over the north and south deeps.

This is a very useful database....


You just need to watch out for the hydro lochs, which are very different now to how they looked when the survey was done. All sorts of other things come into play, depending on the water. For example... Menteith...



When the water temperature turned hot in summer, the fish were to be found in the the deeper areas.

So, it's going to be a water by water thing, and at times a season by season thing...

Excellent stuff!!
Fernworthy Res. please Col, if you have time.
A good size for a venue with no boats. Small enough to be intimate and big enough to give some variety....
Thanks a lot,
Rich
EDIT: I played with your tool (😳) - and it's ~75 acres..

Fantastic piece of work: needs no.1 sticky as is.

Add links to each water with indented page links and it's the defacto guide to uk fishing.

Where I want to be
So, there is a question there for you - what range of size do you prefer to fish?

Anything at all although most of my experience is at the lower end of the range. I'll happily fish a selection of 1 acre puddles in an afternoon, if I was restricted to just one loch for a whole day from the bank it would need to be about 20 or 30 o keep my interest. From a boat 40 acres or so is OK on a calm day but on a windy day that would be a bit small, you'd drift it all in half an hour. I know because I've been there "Where shall we try now Andy?" "Err well we could try the north shore or the south shore or up the middle, again..."

Some are bigger than I think they are, and some seem smaller - though a lot depends on whether they are roughly circular, or consist of all arms and legs. The circular ones pack in so many more acres than the leggy ones.

I'd sooner fish a 10 acre leggy one than a 30 acre round one from either bank or boat. There might be less acres but there is more interest in long legs than one round dollop.

Yeh - agree with you there. I am always amazed that Bharp is only 53 acres - it feels a lot bigger than the ones in the 60s, and takes you a good while to fish round it all. I've never fished Ladybower, but it looks like an interesting leggy one, and at 481 acres, it must seem big when you are out on it. Clywedog another in that vein (586 acres). I wasn't even sure what to include in Trealabhal and what to leave out...



If you set out to fish it from the bank, the whole way round, you would need to take extra sandwiches... 🤪

Well within my comfort zone
Most of our Welsh reservoirs tell you their acreage on their websites some of the lesser known rainbow fisheries are less compliant, IE, the stewponds.

Yeh - I found a few of the stated acreages were quite a bit out, so better to check them yourself...

Yes you can get some small differences but not significant in the main. Just for the record and I can't see them in the list -our local stocked fishery Llyn Cefni on Anglesey is listed as 210 acres and the Snowdonia reservoir Llyn Cowlyd a wild fishery with arctic charr is listed at 240 acres. Similarly llyn Padarn is around 240acres

Carron Valley Res is usually quoted at being 970 or 1000 acres, but it only measured 858 with the map tool. Loch Shin is given as being 5560 acres, but measured 7538 acres with the map tool. That might be because the data has never been updated since the hydro dam was built, which increased the area. I'm not sure why Carron should be smaller, because the dam there was raised some years ago, which increased the area. I might have another go using the satellite view - it might give a different shoreline.

But generally, I enjoyed the exercise, and I am judging what is fishable water, and subtracting islands from totals, rather than just accepting stated measurements. 😜

Just for the record and I can't see them in the list -our local stocked fishery Llyn Cefni on Anglesey is listed as 210 acres and the Snowdonia reservoir Llyn Cowlyd a wild fishery with arctic charr is listed at 240 acres. Similarly llyn Padarn is around 240acres

Happy to include them.

Excellent, thanks for posting the link. Our syndicate lake has now shrunk from 10 acres to 6.7. Lol

I measured Llyn Cefni at 164 acres and Llyn Cowlyd at 262 acres. Llyn Padarn comes in at 256 acres.
