# **How to Choose the Right Blakestone Olive Nymph Trout Flies in Sizes 10 & 12**

When it comes to fly fishing for trout, selecting the right fly can make all the difference between a successful outing and a frustrating one. Among the most effective patterns for trout anglers is the **Blakestone Olive Nymph**, a versatile and highly realistic imitation of natural aquatic insects. Available in **sizes 10 and 12**, these flies are designed to mimic mayfly nymphs, a staple in a trout’s diet.

In this guide, we’ll break down how to choose the best **Blakestone Olive Nymph** for your fishing conditions, covering key factors such as **water conditions, trout feeding behavior, and fly presentation techniques**. Whether you’re a beginner or an experienced angler, understanding these elements will help you maximize your catch rate.

## **1. Understanding the Blakestone Olive Nymph**

The **Blakestone Olive Nymph** is a meticulously tied fly that imitates the olive mayfly nymph, a common food source for trout in rivers and streams. Its **olive-dubbed body, pheasant tail fibers, and soft hackle** create a lifelike appearance that triggers aggressive strikes.

– **Size 10**: A slightly larger profile, ideal for faster currents or when trout are feeding on bigger nymphs.
– **Size 12**: A more subtle option, perfect for clear, slow-moving water where trout are selective.

## **2. Matching the Fly to Water Conditions**

### **Fast-Moving Water (Size 10 Preferred)**
In turbulent rivers or deep runs, trout have less time to inspect flies, so a **larger size 10** works well. The added bulk helps it sink quickly and stay visible in strong currents.

### **Slow or Clear Water (Size 12 Recommended)**
In spring creeks or gin-clear streams, trout are more cautious. A **smaller size 12** appears more natural and is less likely to spook fish.

## **3. Reading Trout Feeding Behavior**

– **Active Feeding**: If trout are aggressively taking nymphs near the surface, a **size 10** with a slight twitch can provoke strikes.
– **Selective Feeding**: In pressured waters, a **size 12** drifted naturally along the bottom often works best.

## **4. Best Rigging & Presentation Techniques**

To maximize effectiveness:

– **Euro Nymphing Rig**: Use a weighted setup with a **size 10** as the point fly and a **size 12** as the dropper for a two-fly approach.
– **Indicator Fishing**: In deeper pools, suspend a **size 12** under a strike indicator for a dead-drift presentation.
– **Swinging Technique**: In faster water, let a **size 10** swing across the current to imitate a dislodged nymph.
