San juan worms

I was reading about these flies in a magazine i picked up at walmart. The magazine;'s name was Fly Fishing America. They said they work well to imitate aquatic worms on tailwater fisheries. Do these work well on the farmington around this time?

Thanks for answering all my questions

SJWs work well during periods of high dirty water as in the case on the Farmington.

The Farmington does not have the correct PH nor mud bottom that is the required habitat for the worms. Tailwaters like the White where I am now in AR , the Big Horn and the Little Red in AR have the right PH and contain lots of aquatic worms.
