Large Treskilling is a small, club-controlled carp lake on the outskirts of Penwithick near St Austell in Cornwall. Managed by Roche Angling Club, it is a straightforward, single water that appeals most to anglers who value a steady, thinking approach over high-stocked “runs water” style fishing. With a modest head of carp in a relatively intimate setting, it suits intermediate and experienced anglers who are comfortable reading the water, working for their bites, and adapting to changing conditions rather than relying on heavily pressured, obvious hotspots.
The lake itself is modest in size, best described as a compact, roughly rectangular or irregularly shaped stillwater that can be comfortably covered with short to medium-range casting. Depths are generally moderate, with shallower margins stepping off into slightly deeper central areas, and the odd change in depth where old features or bank work have left shelves or gentle bars. Margins tend to be the most obvious features, with overhanging trees, reeds, and occasional snaggy areas creating patrol routes. Swim spacing is sensible without being spacious; most pegs give access to a fair slice of water but you will need to be considerate of neighbouring lines. Overall, it is a small enough lake that line lay and noise can make a noticeable difference.
Stock is centred on common and mirror carp, with fish generally running from low doubles upwards. Reports suggest a fair proportion of mid-double carp, with a scattering of better-conditioned upper doubles and the potential for the odd larger specimen for those who put the time in. This is not a high-density, heavily stocked commercial, so blanks are possible, but the rewards tend to be honest, hard-earned fish rather than endlessly pressured “named” carp. Other coarse species may be present, but the water is primarily treated as a carp venue by most regulars.
Fishing here tends to favour solid watercraft over purely static fishing. Careful observation of showing fish, liners, and wind direction usually pays more dividends than simply camping on one swim. Seasonal patterns are typical of a small Cornish stillwater: carp often pushing into the warmer margins and shallows in spring and early autumn, with slightly more central or sheltered zones productive in colder months. Being a club lake, pressure is variable; quieter midweek periods can see the fish behaving more naturally, while busier spells may demand refined rigs, subtle presentation, and sensible line angles to keep takes coming.
The atmosphere at Large Treskilling is generally quiet and uncluttered, with a more natural, club-water feel than a manicured commercial complex. Banks are functional rather than landscaped, and the surrounding area has a semi-rural character, with local background noise rather than complete seclusion. For anglers looking for a straightforward, no-frills Cornish carp lake where results are closely tied to effort and watercraft, it offers a steady, low-key option.
Practical notes
– Ticket/access: Roche Angling Club-controlled water; access via club membership or by arrangement as set out by the club.
– Facilities: Limited on-site facilities; expect basic parking and minimal formal amenities at the lakeside.
– Rules: Standard modern carp-care rules apply (mats, suitable nets, fish handling); check the current club rulebook for bait restrictions, hook patterns, and night fishing permissions before visiting.
