Fishing Doesn't Hibernate in Winter

Winter in Colorado generally means ski gear is taking up most of the space in your car. But be sure to leave a little room for your waders and rod. Although the weather is colder, fly fishing remains hot. Fishing during the colder months is possibly the most rewarding time of year to fish. Not only does catching a fish justify the hours spent in the cold and wind, and give you a reason to spend more time in some of the best fisheries in the country, but winter trout require much more precise technique and skill than any other time of year.

When the air temperature drops, the water temperature drops with it. Like most fish, trout cannot regulate their body temperature and therefore operate at the same temperature as the water around them. When fish get too cold, they become sluggish and dormant.

This is no problem for summer days in Colorado when the water remains in this range, but during the winter, the temperature can drop below freezing. In order to survive, trout will find holes or eddies where the water may be warmer and stay low in the water.

In order to catch the fish in these spots it's best to use a nymph. Fish won't move more than a few inches to catch food. When their body is cold and metabolism is low, it's not worth the risk to waste energy by moving for a small reward that a bug might offer. Therefore, drop nymphs to the bottom of the stream where they can see it and move slightly to eat it.309455_10150416663638665_1273972731_n

When fishing in these winter streams, remember that trout are still alert and they know what it is worth wasting energy for and what is not. Every single move they make and bite they take is a gamble. If they strike and miss, that's a lot of energy wasted for no reward.

Winter streams are generally lower and clearer. Trout will be able to see your tippet if it's too big. Try to use one tippet smaller than what you'd normally use on that body of water. If you use a 5x tippet in spring and summer, drop to a 6X tippet in the winter months. This will not only help that the trout won't see the line, but that the nymph is presented more realistically.

While nymphing is the best tactic for winter trout, don't put all of your dry flies away quite yet. Keep a view on your vest because in deeper pools trout may still rise. This generally occurs in tailwaters (rivers that flow from bottom-released dams). In these tailwaters, the water is moving out of the dam fast enough that the water temperature generally remains in the Trout Zone year round.

During the winter trout will also eat minnows and crayfish, but remember they won't move too far for them to conserve energy. Fishing streamers is a good tactic but just like everything else, they need to be presented next to the trout ensuring they don't need to move as much.

Remember to keep fish in the water as long as possible, especially in the winter as the outside temperature can harm and possibly kill them. Use the fundamentals of proper handling when fishing.

So don't take that fly rod out of your car just yet- or ever. Because fly fishing never hibernates. And when you're stuck in ski traffic, there's no better way than to wait it out by wading out.
