As soon as the snow starts falling in the high country in Colorado, most anglers stow their rods and hang up their waders in exchange for their skis and warmer clothing. I can’t say I’m not partially guilty of this myself, but winter fishing offers opportunities that most anglers choose to ignore.

The beauty of winter fishing is the simplicity. Hatches are much less diverse than those of the summer months. No need to worry about carrying more than a few dries, while nymphing reigns supreme. The water is clear, the flows are low, and the fish are still eating. If you know a thing or two about winter bug activity, you know there are really only two choices: midges or Baetis. And that’s the beauty of it all. Not much changes from summer to winter nymphing, but there are few adjustments that I make in my winter setups. Here are a few things I do to help put more fish to the net in the cold months.

First, that trusty 9-foot leader you’ve been using all summer needs to be a little longer. The clear water and lower flows will help these fish see just about everything around them, and your fly line will be spotted quite easily by their wary eyes. So I opt for a 12-foot leader and attach my tippet sections accordingly. That bright neon indicator bubble you’ve been using all summer will also be spotted fairly easily, so I switch to a natural colored yarn. Takes will be more subtle in winter, and yarn is far more sensitive than bubble-style indicators. Last, your tippet sizes will obviously have to be a touch smaller than summer months, and I find it helpful to put away that spool of Super Strong Nylon and grab my spools of Mirage fluorocarbon.

Hopefully these tips help you put more fish to the net during these upcoming winter months. Make yourself as comfortable as possible, and don’t worry about getting out at the crack of dawn. Have an extra cup of coffee, play with the dogs a little longer and enjoy your favorite stretch of river to yourself. Tight lines!
