Sparsholt is a spring-fed chalk fishery in Hampshire, which puts it in rare company. Chalk-stream country gives it gin-clear, stable, cool water — the trout get a long unhurried look at your fly, and they use it, inspecting the offering like a jeweller examining a suspect diamond. This is the most technical stillwater fishing you'll find: fine tippets, small flies, and an eye for exactly what the fish is taking and where in the water column. The reward is fish in superb condition and an honesty to the fishing that put-and-take waters rarely match. On a calm bright day you'll need everything you've got. A soft overcast with a breath of breeze is a gift — take it. Best read by wind, light and water temperature.
