Upper Mill

Upper Mill sits on the main River Test in Hampshire, offering double-bank chalk stream fishing on one of England's most storied trout rivers. The upper Test combines open main-river water with excellent clarity, and its position in the upper valley means it enjoys reliable fly hatches throughout the season. Wading is permitted, and with access from both banks, anglers can work across the full width of the river — a genuine advantage on a chalk stream where reading the lie and the approach matter as much as the cast itself. The beat holds a mix of stocked and wild brown trout alongside healthy shoals of grayling. Trout fishing runs through spring and summer, with the season building from the first Large Dark Olive, Grannom caddis and hawthorn hatches in April, before the first mayfly of the year arrives in May — typically the most productive weeks on the upper river. June brings Blue-Winged Olive and Medium Olive hatches, with evening rises extending the day well into summer. Grayling fishing is increasingly popular in winter, making this a year-round destination for the committed angler. The beat is rated at adventurer difficulty — the clear water and selective fish demand accurate upstream presentation, and both dry fly and nymph are permitted. One or two rods fish the beat at any time, keeping the water uncrowded. The beat is supported by a strong roster of on-site services, including guided fishing days with AAPGAI/GAIA qualified instructors — well suited to anyone looking to sharpen their chalk stream technique. Catered riverside luncheons, corporate and group events, blast and cast days, gift vouchers, and access to private estate lakes round out the offering, making Upper Mill a practical choice for both the solo rod and a small group planning a full day on the Test.
