Coombe Mill

Just under a mile of single-bank dry fly and nymph water on the Hampshire Avon, Coombe Mill sits on the upper chalk stream reach of this historic Wiltshire river. The Avon rises near the Wiltshire/Berkshire border and flows southward for over 40 miles, and for trout fishermen the pick of the beats are upstream of Salisbury, especially over Salisbury Plain — the country where Frank Sawyer keepered and developed the Pheasant Tail Nymph. One of the most varied chalk streams in the UK, with over 180 species of aquatic plant recorded, it also has one of the most diverse populations of fish, plant and wildlife. Persistent heavy rain early in the season can leave the river a little coloured, but it clears quickly, and from summer through to the end of the season the water clarity is comparable to that of many chalk streams.

The beat targets wild brown trout and grayling on a fly-only, catch-and-release basis, rated as explorer-level water — expect fish that have seen pressure and reward careful presentation over brute-force casting. The trout season opens in time to catch hatches of grannom and large dark olives, and consistently good fly hatches — especially mayfly (Greendrake), which once started can continue for many weeks — make the Avon a firm favourite for fly fishermen. The classic Wessex chalk streams such as the Avon, Test and Itchen have mayfly hatches starting at the end of May and carrying on to early June. Blue-winged olives and sedges carry the fishing through summer and into autumn. Grayling in the Hampshire Avon are thought to be an original, native population, and on the chalk streams they are usually only targeted from October through to the end of December. The grayling season here runs to 30 December, making this a genuinely year-round beat.

Up to three rods fish the bank simultaneously. Rods of between 7½ and 9 ft rated from 3# to 5# lines are the norm, with the longer and slightly heavier outfits suited to wider stretches of the Avon. A 9 ft leader is a sensible minimum. Day-rod pricing runs from £81 in the grayling season to £232 during the mayfly, with main-season days at £156. A fishing hut and toilets are on site. Wading is not permitted; all fishing is from the bank.
