Isis Lake No 1 is one of the older gravel pits in the South Cerney area of the Cotswold Water Park, Gloucestershire. It is a single, self‑contained carp water rather than part of a busy day‑ticket complex, and tends to appeal to anglers who are comfortable reading clear, pit‑style venues. It suits intermediate and experienced carp anglers who are prepared to work at their fishing, watch the water carefully, and adjust tactics to changing conditions rather than rely on heavily stocked “runs water” style angling.
In layout terms, Isis Lake No 1 is a small‑to‑medium‑sized gravel pit rather than a large windswept reservoir. Depths are generally moderate, with a mix of shallower shelves falling away into fuller water and the odd deeper pocket or gully created by past extraction. Submerged bars, firmer gravel seams and patches of low weed are common features, along with productive marginal areas where the bank shelves more gradually. Swims are spaced so that most offer a defined section of water rather than everyone fishing the same features, though line angles can still matter. The banks have a reasonably mature feel, with some bank-side cover and trees influencing light and wind on the water.
The stock is centred on carp, with a mix of mirrors and commons typical of Cotswold Water Park gravel pits. Exact numbers and strain details are not widely publicised, but this is not an over‑stocked “bite‑a‑chuck” lake; fish tend to move in groups and show themselves when conditions are right. Most captures are from the sort of size brackets that keep things interesting without being extreme, and there are occasional reports of better specimen‑class fish for those prepared to put in time and build an understanding of the water. Other coarse species may be present but are not usually the primary target.
Fishing Isis Lake No 1 is largely about watercraft rather than simply dropping onto a known “flyer.” Watching for shows, liners, and subtle changes in bird life can be more important than rigidly sitting on a predefined spot. As with many clear pits, carp behaviour is quite seasonal: they can be very visible and active in warmer months and more location‑dependent and finicky in winter and high‑pressure conditions. The lake does see a reasonable level of angling pressure, which can make them line‑shy at times; quieter periods and off‑peak weather windows often reward a more mobile, thinking approach.
The general atmosphere at Isis Lake No 1 is more “mature gravel pit” than commercial match‑style venue. Its South Cerney setting means there is human activity in the wider area, but the banks themselves feel relatively self‑contained once you are in a swim. It is not totally secluded, yet it offers enough space and character for anglers who enjoy settling into a pit and unpicking its moods rather than fishing a heavily manicured complex.
Practical notes:
– Access type: arrangements can be club, permit, or controlled access rather than open casual day‑ticket; check current status before travelling.
– Facilities: parking is typically close enough for sensible barrow access; broader amenities are associated with the surrounding South Cerney developments rather than dedicated to the fishery.
– Rules: expect standard modern carp fishery requirements (appropriate tackle, fish care, and rig safety); confirm any specifics on leaders, hook patterns, and night fishing before your session.
