Break out the neoprene: Winter stream fishing is a perfect opportunity to stay outdoors and catch fish | Fish & Game

But for those willing to don their thickest neoprene waders, set up shop on an icy riverbank for a few hours and fuss with frozen guides, there are still several opportunities to sharpen one’s angling skills, take in Idaho’s beautiful winterscape and hook a few fish.

The benefits and strategy of winter stream fishing

There are several benefits to fishing rivers and streams during the coldest part of the year. For starters, you may have the whole stretch of river bank to yourself. For a handful of folks, fishing plays second fiddle to other winter hobbies like fly tying, skiing or making a pot of chili in the slow cooker. It shouldn’t be too difficult to find a nice stretch of river where you won’t have to worry about summer crowds.

Seek out slow, deep water where trout and whitefish will most likely be holding, expending as little energy as possible. Look for slow pockets or pools where water is barely flowing.

Just because fish are moving slower in the winter doesn’t mean they’re not still looking for an easy meal. Insect hatches are sparse in winter, but that doesn’t mean they still aren’t around as a food source for slow-moving fish. Fish can be frustratingly picky this time of year, so presentation and food size is vital.

As a general rule of thumb, use smaller bait and flies than you would in spring and summer.

The same goes for tippet. River flows in winter slow down dramatically and tend to be lower and clearer. That means it’s even easier for fish to see right through a poorly-executed presentation. It might be wise to downsize your tippet from what you usually run in the spring and summer, such as a 4X to a 5X.

Technique, technique, technique

Once you got your rig set up, it’s good to try different techniques that you might not have tried before in the warmer months.

Dead drifting is critical in winter because trout won’t chase a fly in cold water. To dead drift, simply let the slow-moving current carry the fly either on the surface (dry fly) or just beneath the surface in the upper column of water (bait, nymphs, midges). If you see dimples on the water, it may be fish feeding on drifting insects, which will likely be tiny midges or mayflies.

Occasionally stream fish will rise for dry flies, such as small midges or olive mayflies, during the winter. But it isn’t too common. Instead, save yourself a few extra grams of weight and keep that box of dry flies at home. A small midge emerger or a tiny olive mayfly emerger will be the only surface flies you need.

If fishing for trout or steelhead, try swinging a fly by keeping the fly in the upper part of the water column. Steelhead and trout will often feed upwards, so a well-placed fly swinging across the upper portion of the water just may catch their eye.

If the fish aren’t going for small flies like midges and stoneflies, it may not hurt to lob a streamer out there to test the waters, so to speak. Streamers can look like a big, easy meal when presented slowly, but don’t expect trout to vigorously chase them like they do in summer.

The only thing sweeter than netting a jumbo fish in the middle of winter is netting a jumbo fish in the middle of winter after eight hours of uninterrupted sleep. Unplug the alarm clock. Disable your phone’s sleep reminder. Brew that extra pot of bold roast, and slam that extra waffle. Winter fishing means one thing to many anglers: sleeping in. This time of year, fish will be right there with you, figuratively speaking.

With most winter fisheries, fish won’t be getting after it until mid- to late-morning. Unlike peak summer conditions, fish will be most active during mid-afternoon on sunny days, and even longer into the afternoon on cloudy days.

It’s easy to see how excited one might be about submerging their southern hemisphere in icy water all for the hopes of catching a fish, but rest easy (and long) knowing that those fish will still be waiting for you when you hit your local river or stream later in the morning.

Now that you’re well-rested and know what to try on fish, here’s where to find them. See Fish and Game’s Fishing Planner to learn more about each location.

Lower Lochsa and Selway rivers: All provide good opportunities to catch whitefish during winter, and also have catch-and-release trout fishing.

St. Joe River: This river provides winter fishing opportunities for cutthroat trout and whitefish.

South Fork of the Snake River: This has year-round trout fishing and there’s no limit on rainbow trout. There’s also lots of opportunity to catch whitefish during winter.
