Slow going — pick your moments
River temperature is the limiting factor today, not the flow. Fish dawn or dusk if you go at all, and handle everything with extra care.

How to fish it · for brown trout
When
Nymphing can work through most of the day.
Where
Cover mixed depths.
Method
Start with tight-line nymphs and adjust if fish rise or drift higher.
Kit
9 ft #4 rod, floating line, 12 ft tapered leader to 4–5 lb fluoro tippet.
Why this works
⚠️ Water at 19.6°C — above the brown trout caution line (18°C). Fish dawn or dusk only. Land it fast, wet hands, no air shots. Otherwise poor — water clarity is in the right range.

About this water

Practical Sauerland fly-fishing water on the upper Ruhr around Bestwig. This is the missing NRW counterweight to the Bavaria/Black Forest bias: realistic day-trip trout and grayling water for anglers from the Ruhrgebiet, Cologne/Düsseldorf corridor and wider western Germany.
