Notes the engine attaches
Circle hook: do not set the hookhook
Reel down until the line comes tight and let the rod load. A circle hook slides to the jaw hinge and rotates closed on its own. A conventional swing pulls it straight back out of the mouth: the technique change is mandatory, not stylistic. Read the guide.
River Run is wadeable and coldwaders
Water down to around 38°F and wade access available. Chest waders extend both your range and your season here substantially, and standing in 45°F water in shorts ends a trip in about twenty minutes. Read the guide.
Why these numbers
- River Run runs 3–18 ft and Salmon (Coho / King) feeds at a depth bias of 0.60 (0 is the surface, 1 is hard bottom), so the engine puts the fish near 12 ft.
- Current rates 0.70, which the engine turns into roughly 2.1 oz to hold bottom and warns under half that. This build carries 1.5 oz.
- The water is stained and Salmon (Coho / King) rates 0.60 for line shyness and 0.60 for abrasion. That is why the business end is 20 lb fluoro: it takes the teeth, gill plates and structure so the mainline does not, and fluoro nearly vanishes in clear water.
- Typical fish run 6–30 lb. That sets the 10 lb drag floor (this reel makes 13 lb) and the hook strength floor of 36 lb (this hook is rated 70 lb).

Scope: the solver builds a tied hook-and-line rig from the parts in our catalog, cheapest first among builds with the fewest problems. Hard baits with their own trebles, flies, and field gear (waders, clothing, boats) are left to you. A different catalog would give a different answer, and the studio will check whatever you swap in.
