Tricos Persist on the South Platte River into MId-September

It is always difficult to know how long the Tricos will continue to hatch on the South Platte but as of 9/13 the little bugs are thick. Fish can be found gulping the spinners up and down the canyons and meadows of the South Platte. People often ask me what is "The" fly, yet it is best to use an assortment of "tiny little flies" and switch them out as the fish seem to start ignoring certain patterns. My clients seem to be doing best with "anything that floats" in the size 24 range. But we are also doing well with "drowned" tricos below the surface. It is hard to beat a size 24 sparkle wing RS2 in gray or black and a spent-wing trico spinner in black and white. Fish continue to feed on the remnants of the hatch well into the afternoon. The small bugs are imprinted on the trouts brain, so they respond to a well placed fly that resembles the trico most of the day.
