Fly Fishing in Colorado during the winter months can be excellent but it can also be very challenging. Constantly de-icing your guides with freezing fingers certainly takes hearty a angler, but it allows us get outside away from the daily grind. A couple benefits of winter fly fishing is that there is less pressure and fish tend to be easy to locate. Deeper slow moving runs hold the majority of fish during the winter months allowing anglers to spend time focusing fly selection and presentation. Midges are the dominant fare in a trout’s diet this time of year but due to the multiple sizes and colors of midges it is important to have a variety of these fly patters. Some of my favorite color midge fly patterns are Black, Olive, Red and Cream. It is amazing that changing the color of a fly so small that it can have an impact of your fishing success but it does. Doing a little research on the water will help determine what color midges are floating around under the surface. Picking up submerged sticks or rocks is a good way to find midge larvae and while it can be painful to stick your hands in 30 degree water it may make the difference in your angling success. Also try and focus on the depth of your nymph rig. A lot of times we try to go directly to the bottom with our midges and while this does work, there are times when you can be too deep. If you are starting to see midges hatch sporadically or find them on the river bank try lightening your nymph rig and see what happens. As these insect get active in the water trout will start to suspend to eat midges as the emerge. Here are a few of excellent midge patterns for winter fly fishing in Colorado.
The Flash Bang Midge is a great fly pattern that should be in every anglers fly box. The glass bead
on these midge patterns adds a little extra weight and also looks like a small air bubble. The Flash Bang Midge works well in the early winter as fish transition from eating Baetis to Midges. It also works well deeper into winter as a lead fly in a two fly set-up. The glass bead allows this fly pattern to be fished higher in the water column with out adding much weight making the Flash Bang an excellent pattern to present to suspended fish.
The Jujubee Midge is a common pattern that you will find in early every fly shop in Colorado. Developed by Charlie Craven, this fly has been taken out of many a trout’s lips and is a proven fish catcher. The Jujubee midge pattern is great for tailwaters and freestone rivers alike. The added flash gives this fly a little more flare grabbing the attention of underwater lurkers. This is another fly pattern that works well early in the fall throughout the winter.
The RS2 is a fly pattern that more times than not is my go to fly. I am not exactly sure if this is classified as a midge pattern but who cares, It works in so many scenarios throughout the year and catches a ton of trout. I prefer this fly with a flash wing and in multiple sizes. The basic design of this fly pattern is nothing fancy to look at but neither are midges. RS2’s are great for Trico’s hatches in the Summer and Midge hatches in the winter. If there are any flies out of these three that you must have it is the RS2.
