What Trout were Eating in Vail and Denver April 5th and What I Offered Them.
4/5/2018 Gore Creek runs through the center of Vail, Colorado and has been nicely preserved as a wild stream in the center of a village. It has been screened from the highway and developments by large pines and open meadows. The freestone stream has been left quite untouched except for short stretch near the center of town. I've caught rainbows, cutthroats, browns, and brook trout in the village.

This west slope stream flows to the Eagle River which joins the Colorado River to flow to the Gulf of California and the Pacific or to irrigate the produce patches of California. At an elevation of 8,100 feet a rainbow trout was eating mature mayflies, midges (adult and nymph stage) and mayfly nymphs. You may be able to identify other species. I found a pool below a riffle that had many trout taking emergers. My three fly rig had an Elk Hair Caddis indicator fly, a Trico dry than was sometimes floating, a tiny blob of sink putty, and a foam back chocolate emerger. I caught a brook trout, brown, and a rainbow from the pool shown below drifting down the center and along both seams. Air temperature was about 40 degrees, water temperature was 39, water was crystal clear. This Gore Creek water is very near its Rocky Mountain source from the snows on Vail Pass.

Later in the day on Clear Creek just upstream of Golden Colorado at an elevation of 5725, and air temperature of 65 and a water temperature of about 44, and the water was clear. There was no surface activity but the same three flies caught 10 fish, including this nice brown. Clear Creek drains to the South Platte which eventually joins the Missouri and enters to Gulf of Mexico or winds up on a crop circle of wheat or soybeans in Colorado. This water is 40 miles from its source and has traveled through one former superfund site, two small towns, and 40 miles of Interstate 70.

My first sample of a small brown yielded just this midge and an annelida.

My second sample of a 10 inch brown showed almost the same composition as the stomach sample 2,400 feet higher in the West Slope drainage. The fact that the bug sample is very similar is quite amazing. The fact that the same rig of flies was attractive to fish is also amazing. The fact that there was no surface feeding on Clear Creek is puzzling to me.
