Parks' Salmon Fly

Parks' Salmon Fly

 One of the most enduring contributions of Parks' Fly Shop in Gardiner, Montana is the Parks' Salmon Fly, an improved version of the old Sofa Pillow used to imitate the giant stoneflies or Salmon Flies on the Yellowstone River and its tributaries. In 1954, Merton Parks found the older imitations of the giant stonefly unsuitable and created the Parks Salmon Fly. The fly remains popular and in use still today. Charles Brooks, a master Yellowstone fly fisherman, called the Parks' Salmon Fly one of his top three stonefly imitations. 

Imitates Pteronarcys californica 

The Parks' Salmonfly imitates an adult salmonfly (Pteronarcys californica), a species of giant stonefly common in higher-velocity streams and rivers, on medium to large-sized unconsolidated substrates. Salmonflies are found across western North America from California to British Columbia and throughout the Rocky Mountains. On the Yellowstone River and southwest Montana where the Parks' Salmonfly originated, adult salmonflies typically emerge in late June through July. Trout aggressively feed on adults that fall in the water. 

Materials 

Adult salmonflies are large insects up to 2 inches (5.1 cm) long, so imitations are tied on large, long hooks. Size 6 is the most common but they can be tied on size 2-8 2X long hooks. Merton Parks improved on the original Sofa Pillow by replacing the red floss body with the more bulky and buoyant acrylic yarn in tangerine–a color closer to the living insect. The quill tail and fox squirrel tail wing were replaced with bulkier brown bucktail. The tail, body, wing and hackle are all tied very bulky to create a large profile on the water. 

Variations 

Elk mane can be substituted for the bucktail. Smaller versions of the fly (size 6–10) tied with lighter bucktail, ginger hackle and yellow yarn are used to imitate Golden stoneflies (Hesperoperla and Calineuria).
