Split shot is a fundamental component in nymph fishing, allowing anglers to adjust the weight of their rigs to ensure flies reach the desired depth. Understanding the various sizes, materials, and placement strategies can significantly enhance fishing effectiveness.
Water conditions such as depth, current speed, and the weight of your flies can vary significantly. Having an assortment of split shot sizes allows for precise adjustments, ensuring your nymphs drift naturally at the optimal depth. For instance, in deeper or faster waters, heavier split shots may be necessary to reach the strike zone, while lighter weights are suitable for shallow or slow-moving streams. Adjusting the weight can be crucial, as insufficient weight may prevent the fly from reaching the target depth, while excessive weight can lead to frequent snags.
Split shot sizes are typically denoted by numbers and letters, with larger numbers indicating smaller weights. Here are some common sizes used in trout fishing:
| Size | Weight (grams) | Weight (ounces) | Notes |
|---|---|---|---|
| SSG | 1.80 | 0.0635 | Ideal for deep, fast-moving waters where significant weight is needed. |
| AAA | 0.81 | 0.0286 | Suitable for swift currents and deeper pools requiring moderate weight. |
| BB | 0.40 | 0.0141 | Versatile size for general nymphing applications. |
| No. 1 | 0.30 | 0.0106 | Ideal for moderate depths and currents. |
| No. 4 | 0.20 | 0.0071 | Useful for fine-tuning weight in delicate presentations. |
| No. 6 | 0.10 | 0.0035 | Appropriate for shallow waters or when minimal weight is needed. |
Note: Actual weights may vary slightly depending on the manufacturer.

Traditionally, lead has been the preferred material for split shot due to its high density, allowing for smaller and heavier weights. However, environmental concerns have led to the development of non-lead alternatives, such as tin and tungsten.
Comparison:
| Aspect | Lead Split Shot | Non-Lead Alternatives |
|---|---|---|
| Density | Higher density allows for smaller, heavier weights. | Lower density requires larger sizes to achieve the same weight. |
| Environmental Impact | Potentially toxic to wildlife; banned in some regions. | Environmentally friendly; safer for wildlife. |
| Availability | Widely available but subject to regional restrictions. | Increasingly available; may be more expensive. |
It's important to note that in certain areas, the use of lead split shot is prohibited due to environmental regulations. For example, lead split shot cannot be purchased in New York.

The strategic placement of split shot on your leader is crucial for achieving the desired fly depth and presentation. Here are some key considerations:
Determining the Amount of Weight Needed:
Water Depth and Current Speed: In deeper or faster waters, additional weight is necessary to ensure the fly reaches the target depth promptly. Conversely, in shallow or slow-moving waters, less weight is required.
Fly Weight and Size: Larger or heavier flies may require less additional weight, while smaller, lighter flies might need more assistance to sink effectively.
Placement Strategies:
Above the Fly: Common practice involves placing the split shot approximately 12 to 24 inches (30 to 60 centimeters) above the fly. This setup allows the fly to drift naturally while ensuring it reaches the desired depth.
Spacing Multiple Split Shots: In situations requiring significant weight, using multiple smaller split shots spaced evenly can be advantageous. This approach, known as "shotgunning," creates a more natural presentation and reduces the risk of creating a single heavy point that may snag.
Attaching to Tag Ends: To minimize the risk of losing the entire rig due to snags, some anglers attach split shots to tag ends (short lengths of line extending from knots). In the event of a snag, the split shot can detach, preserving the rest of the setup.
