Martin Cottis's Tip of the Week

Tougher week with such cold north east winds. As it has gone round to the west more of the lake is opened up. Quality fish coming out. But, fish still high and taking buzzers and almost anything near the surface.

5-Day Outlook as of 6/6/25

Fish to be found in Villice, through the cages and along Walley and the dam areas. The weed at Wick, Roman Shallows and along the Eat Shore has become pretty dense. The fish remain high in the water.

Techniques & Tips as of 6/6/25

For nymph fishing, long leaders and team of three flies - "buzzer" pupae in various colours. It is important to move the flies VERY slowly if at all! With dry fly, best to use two flies on a 10 - 12 foot leader spaced about five feet apart. 12 on the point and 14 on the dropper. For the pike a wire trace is compulsory, and as there are some very large fish in the lake, a minimum tippet strength of 25lbs is required. Large (2/0 and 3/0) bait immitations are best.

Description: About Chew Valley Lake

Chew Valley Lake at around 1400 acres is one of the largest reservoirs in the south of England. Construction work began on the lake in 1953 and in June 1956 it was officially opened by Her Majesty, Queen Elizabeth II. Since then it has provided wonderful trout fishing for both local and visiting anglers. Found to the south of Bristol and handily placed for flights into Bristol Airport, Chew has long been a venue sought after by anglers wishing to fish small and mostly immitative nymph and dry fly patterns. The new Lodge was opened in 2000 by the celebrated angler and actor Bernard Cribbins.
