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

Brown Trout fly box

A small Dartmoor spate river that rises and falls in a hurry — fish the falling water as it clears, working every seam and pocket with a spider or a small dry. Wild browns are the point; the salmon and sea trout are a bonus.

About this water

A Dartmoor river of real character — the East and West Dart meet at Dartmeet in classic moorland scenery. Granite-bedded with wild brown trout in the upper reaches and salmon and sea trout lower down. Fast, rocky water that rewards nymph and wet fly. Atlantic salmon are assessed by the Environment Agency against each river's Conservation Limit — many principal rivers are classed 'at risk' with mandatory catch-and-release byelaws; check current rules before fishing.

Under the surface

The Dart is born twice on the high granite of Dartmoor — the East Dart off Hangingstone Hill, the West Dart below Cut Hill and Fur Tor — the two moorland streams meeting at Dartmeet to run some seventy-five kilometres south to the sea at Dartmouth. The upper river is true spate water: peat-stained, tumbling over granite ledges and through a string of cascades and pocket pools, rising hard and falling fast after rain off the moor. Below the moorland edge it gathers into a wooded, boulder-strewn freestone river through the steep Dart valley, with deeper holding pools for running salmon and the sea trout — peal — for which the Devon rivers are known. The granite gives clean, acidic, quick-clearing water. Wading is boulder work, slick and uneven under oak shade; the upper falls demand a careful foot in spate.

What would change the calculation
Cooler water — back toward the 10–16 °C ideal band — would lift the score and ease welfare.
The dawn and dusk windows score higher than the midday lull.

Sea trout: Variable seasonal (2026)

Salmon: Negligible (2026) — EA 2024 Salmon Stocks Assessment classifies this river 'at risk' — egg deposition below Conservation Limit. Conservation priority; not a salmon fishing destination. The Dart has lost most of its salmon run over the past two decades.
