    "behavior": "Aquatic worms become dislodged from substrate during storm runoff and flood events, tumbling helplessly in high flows where they are highly visible to opportunistic trout. Fish eagerly consume these protein-rich invertebrates as they drift past in chocolate-colored water, especially during spring snowmelt and after heavy rainfall."

  "behaviorPresentation": "**Natural Behavior**: During storm runoff, aquatic worms release from substrate and tumble downstream with high visibility in chocolate-colored water, their constant squirming motion making them easy to locate. Fish eagerly consume these during flood events when other prey is scarce.\n**Where Trout Eat It**: Fish hold near the bottom in slower runs, deep pools, and along structure at depths of 2-6 feet during off-color water.\n**How to Fish It**: Dead drift near bottom using standard nymph techniques with jigging rod tip lifts to imitate squirming movement.\n**Best Water**: Target runs, pockets, riffle edges, deep pools, and bottom structure during stained water and runoff conditions.\n**Strike Type**: In high water, indicator drops are often aggressive and unmistakable as fish gorge on drifting worms. Watch for sudden plunges or sideways movements signaling committed takes.",
  "fishingStrategy": "**Rigging Suggestions**: Fish on 4X-5X fluorocarbon tippet with 9-foot leader. Effective solo or positioned as point fly in multi-nymph rig 18-24 inches above a smaller natural pattern. Use split shot or indicator for depth control.\n**Seasonal Timing**: effectiveness with peak productivity during March-May runoff periods and October-November when aquatic worms become dislodged during flow fluctuations. Excellent during any stained water conditions throughout the calendar.\n**Pro Tips**: Pink, red, and chartreuse variations work best in stained water. The sparkle materials provide both visibility and triggering flash.",
  "overview": "A flashy, synthetic take on the San Juan Worm, this pattern uses sparkle chenille for the body, sometimes with a bead for added weight. It's simple to tie and highly visible in stained water—perfect for high water or runoff conditions."
