Cow Green is surrounded by beautiful scenery, an area of outstanding natural beauty and Britain's first European Geopark. Cow Green is also a site of international importance for its rare flora, which is unique to Great Britain. For anglers, nestled within the reservoir are the original upland brownies, one of the finest brown trout populations in England. Descendants from the wild brown trout which lived in the streams before the dam was built.

Consession £7

Full Day Permit £9.


The reservoir is about 2 miles long and is over 500 metres above sea level. It is situated against the dramatic backdrop of Widdybank Fell, and now feeds the torrent of Cauldron Snout, a 200-foot cascade down dolerite steps, which lies below Cow Green Reservoir. Dramatic photographs can be taken of the reservoir and the fells from almost any point along the shoreline, or from on top of the dam itself. To get the best out of this water you need to keep on the move. Brook fishing methods, light tackle with sparsely dressed spider patterns work well. Lighting-fast reflexes, hard fighting brownies with unique colours and markings. These fish are a joy to catch!

Dates & times: The season is from 22nd March to 30th September and fishing times are from 8am to 9pm or sunset (whichever is sooner). Fishing commences at 8am once anglers have signed in.

Try it days: During the season on Tuesdays and Saturdays Derwent reservoir offers fishing tuition. This can be for novices or anglers keen to improve their skills in the art of both fly fishing and multi-bait fishing. The price ranges from £15 for a junior and £30 for an adult and includes all tackle hire, rod license and three hours of tuition.

Fly: Spring and Autumn, When fly fishing, an intermediate line may be required on the colder days in March and April, when a small Black Tadpole on the point and drab Palmers on the droppers should get plenty of action. From May onwards, use a floating line as the trout are usually at the surface, often free rising to all manner of terrestrial insects and the prolific hatches of small Black or Olive Buzzers which are evident throughout late spring and summer. At this time, small traditional patterns such as Black Pennells, Invictas and Spiders are consistent fish catches with dries including Hoppers, Sedgehogs and Cul-de-Canards doing very well when fish are rising

Spread over a shallow basin in the upper reaches of Teesdale, Cow Green is encircled by the Pennine Moors. This is the highest of our lakes and it offers stunning views of the surrounding Pennine moorland. Widdybank Fell on the north eastern shore is a National Nature Reserve managed by Natural England. There is a footpath around the water which links to the Pennine Way. Cow Green at the head of Teesdale is in wonderful and dramatic walking country. The area supports rare alpine flora. Nearby, the foaming cataract of Cauldron Snout plunges dramatically down from the reservoir outflow, to form a spectacular confluence of the river Tees and Maize Beck, beneath Falcon Clints. The waterfall can be reached through the reserve on the dam access road. There is a nature trail which is wide enough to allow access by wheel chair. The area from the former boat house to the western end of the dam forms part of the National Nature Reserve managed by Natural England and public access and fishing are prohibited.

Online Permits: All permits are for a day only and catch limits must be shared if more than one person is fishing. All anglers aged 12 or over must also be in possession of their own valid individual Environment Agency rod license, which if not already held can be bought from the shop.
