Hi' Rupert. Over the past 23/24 years I have tried, at odd times, to convince readers of a weekly angling column, that I write for our local paper, that there are pike in Ullswater. Sorry, I should have started with a welcome to FFF.

I was particularly pleased to receive a phone call yesterday from a former Penrith AA member who has been a keen scuba diver for many years, and who is an instructor. He found a pike under Glenridding pier at the head of the lake in 1986, which was about the time I first learned, via asking the NWWA rivers Division Fisheries Officer to confirm the suspicions of a friend and I.
I also learned, yesterday, that the same lad ( he's 76) has seen a shoal of rudd under the steamer pier at Pooley Bridge, plus a shoal of chub in Gale Bay, and several pike in a basking party a few years after his first sighting; so you would be doing me a favour if you caught a pike in Glenridding Bay.
The biggest pike that my informant has seen was a 20lb specimen in Loweswater. The biggest I have heard of in recent years was a 32 lb fish from one of the tarns; but that's all I'm allowed to say on that one.
Bassenthwaite and Derwentwater are probably the the most prolific pike lakes; only fished Derwentwater twice with fly for pike, and caught a 5lb jack on the third throw with a leadhead deer hair muddler type of beast that I tied some years ago. I know one very well-known angling/fly-tying celebrity who has had a lot of pike on Bass. lake by trolling heavy tube flies along the marginal weedy areas.
As mrtrout writes above, we hope to have a go at the Ullswater pike this 'backend', hopefully before it is too cold, and while they are on the prowl.
Good luck. TerryC
