Winter Nymph Fishing Strategies – Part One: Depth Control, Weight Selection, and Indicator Setup

Winter fly fishing can be some of the most rewarding—and challenging—trout fishing of the year. As we discussed in our previous series, How Trout Feed in Winter, cold water temperatures slow a trout’s metabolism and drastically reduce feeding opportunities. When water temperatures fall into the 30s, the margin for error in presentation becomes very small.

In winter nymph fishing, success consistently comes down to three core factors: depth control, proper weight selection, and an efficient indicator setup.

At Murray’s Fly Shop, most winter nymphing issues we see aren’t about fly choice—they’re about getting the fly deep enough and keeping it there.

Why Depth Control Matters in Winter

As water temperatures drop, trout move into slower, deeper water where they can conserve energy. In cold conditions, fish rarely move far to feed, which means your nymph must drift directly through their feeding lane.

If your fly rides even a few inches too high, it may never be seen. In winter nymphing, depth is more important than fly pattern.

Winter Depth Control Tips

  • Target slow seams, tails of riffles, and mid-sections of pools
  • Fish deeper than you think you need to
  • Adjust depth before changing flies

A reliable rule of thumb: if you’re not occasionally ticking bottom every 3–5 drifts, you’re not deep enough. If you’re hanging up constantly, reduce weight slightly.

Weight Selection: Getting Down Without Overdoing It

Proper weight selection allows your flies to reach depth quickly while maintaining a natural drift. Too little weight keeps your flies above the fish, while too much weight causes snagging and drag—both are equally problematic. Your goal is a natural drift so if you’re having to pull the fly across the bottom, that doesn’t appear natural to the fish.

How to Choose the Right Weight

  • Start by finding bottom, then fine-tune for consistent contact
  • Tungsten bead nymphs help achieve depth quickly (tungsten is heavier than brass)
  • Add split shot incrementally until you reach bottom
  • Expect to adjust often—your first setup is rarely perfect and the current constantly changes from pool to pool

Keep in mind that in cold water, it’s better to add weight and slow the drift than to fish light flies that never reach the strike zone.

Weight Placement: Two Effective Approaches

1. Heavy Anchor Fly

Using a heavier point fly or anchor fly (the fly on the bottom) is often the cleanest solution, especially in multi-fly rigs.

  • Adjust size of the fly on the bottom based on it’s bead
  • Jig-style patterns and slim nymphs like Perdigons tend to hang up less
  • The goal is fast sink rate with a natural drift

2. Split Shot

Adding weight above the fly / flies offers precise control when using a micro shot assortment.

  • Place split shot 6–10 inches above the top fly
  • Avoid stacking weight directly on the fly
  • Distribute weight along the leader for a smoother drift

The closer weight is placed to the fly, the closer it rides to the bottom. If hang-ups increase, reduce weight size or move it farther up the leader.

Indicator Sensitivity in Winter

Winter strikes are often extremely subtle. Large floating indicators create resistance due to faster surface currents, making light takes harder to detect.

Best Indicator Traits for Winter Nymphing

  • Small and lightweight
  • Highly sensitive
  • Easy to adjust for depth

Products like Murray’s Indicators, High N Dry Sighter Wax, and Palsa Foam Strike Indicators consistently outperform oversized bobber-style indicators in cold water.

Indicator Depth Setup

Floating indicators should generally be set at 1.5 to 2 times the depth of the water being fished. This allows flies to reach bottom while maintaining a vertical leader angle.

Murray’s Indicators function differently—they slide on the leader and do not float. They can be used as in-water reference points or above-water sighters, and typically require minimal repositioning once set.

Fine-Tuning Depth

  • Adjust floating indicators before changing flies
  • Modify depth as water depth changes
  • Use subtle upstream mends to slow the drift

Depth control and drift speed work together—slow and deep wins in winter.
