Weekly River & Hatches Update

June is absolutely my favourite month to be on the river amongst the abundantly green English countryside. It may not the easiest month from a fishing perspective as we relearn that fish don’t always throw themselves at a size 8 Mayfly.

Weather:

Last week bucked the trend a little, with blustery conditions and even some heavy rain. Mild winds from the southwest of up to 18mph, but thankfully this week average temperatures are 21 degrees and climbing towards the end of the week, and conditions seem much calmer; overcast, with sunny spells and gentle breezes from the west. The sun officially sets after 9pm. Sunrise: 04:50 GMT. Sunset 21:23 GMT. UV: High, Pollution: Low. Pressure: 1011mb.

River Flows:

The river flows currently range between normal and below normal as rated by the Environment Agency. Whilst there has been limited rainfall in the last few weeks, the chalk stream aquifers are still full after a wet winter. Thankfully, the riverbanks are drying out (finally!), so in most cases walking boots will suffice, though a pair of wellies or thigh waders might just help coax your quarry to the water’s edge.

Hatches:

My general rule for mid-late June is to be eclectic in your fly choices and be prepared to change a lot, with everything from a size 10 French Partridge down to a size 18 Greenwell’s Glory with a variety of sedges and unwinged flies in between with no single fly predominating. Where you cannot yet nymph work those deep fish. It is amazing from how far below, once you get the right fly, they will move from.

Fly Patterns:

Over the past few weeks, the trout have gorged themselves on Mayfly sometimes to the point of refusal, so now is generally the time we start to turn to smaller dry fly patterns to outwit our wily quarry. At the front of my fly box this week will be Blue Winged Olive (BWO), Klinkhammer, Grey Wulff and Elk Hair Caddis.

Our Seasonal tips:

As a general rule, we would expect surface action timings to be determined by the weather on the day, again generally warm and sunny with no rain forecast this coming week. Think harder about lighter tippets, concealment and keeping the sun to your face. Shadows and line flash will give you away in a moment. Be prepared to change your fly often; if your target fish ignores a fly more than twice, change size or fly.

News, events and catch reports:

  • Matt had a great couple of days at Barton Court and School Farm – “Special mention is how well Barton Court is coming on. Harry is doing an amazing job. Having been three previous times this year surpassed all others. Everything was immaculate and couldn’t have been improved. School Farm was also immaculate, but we had nonstop rain all day, no hatch. That said all three of us caught. “

  • Julian also had a great day at Avon Springs – “Many thanks for arranging another splendid days’ fishing, this time at Avon Springs. The heavens opened after lunch but that did not put a damper on our day which ended with my brother catching his first proper fish: quite a celebration! Jeremy met us on arrival and was most welcoming and informative. Please pass on our thanks. The setting was even better than I was expecting: a very nicely kept fishery and good facilities too. Having the lakes and the river to fish meant that our mixed ability could be tested properly (and flattered!). I had three lines broken by some lively fish. One take was so strong I wasn’t sure if it was a small submarine… I would definitely recommend this fishery, particularly to a party of mixed ability (an ideal father and son spot). We cooked the fish over an open fire that evening at our campsite (the lovely Wild Camping Dark Lane near Pewsey wildcampingwiltshire.co.uk). The sun came out and our mood was radiant too”.
