What bead size works best at moderate Vaal River flows?

At moderate Vaal River flows of roughly 20 to 35 cumecs, a 2.5 to 3.5mm tungsten bead on a slim Perdigon or PTN is a practical starting point for bottom contact.

How should I adjust flies below 15 cumecs?

In lower, clearer flows, reduce bead size, fish slimmer micro profiles, use longer leaders and target slower seams where fish are less likely to spook.

How should I adjust flies above 40 cumecs?

Above 40 cumecs, increase anchor fly weight, shorten dropper length and use short controlled drifts through softer edges and safer lanes. The current field-observed flow is around 22 m³/s, inside the moderate 20–35 cumec range where a standard two-fly Euro rig and 2.5–3.0 mm tungsten beads are a practical starting point.

Where can I find more Vaal River flow and Yellowfish planning answers?

Vaal River Flow Rate & Levels | Current Yellowfish Conditions

Quick Answer

Current field update: the Vaal is around 22 m³/s with water temperature around 18°C. Conditions are green and highly fishable. 2.5 mm tungsten beads are doing most of the work today; move to 3 mm in faster, deeper runs where you need extra weight to reach and hold the feeding lane.

The Season Is Underway · Guided Dates

Knowing the flow is one thing. Fishing the right lane is another.

A guided Vaal River day turns today’s conditions into practical decisions: where to wade, which seam to fish, how deep to run the rig and when to change weight. Current conditions are around 22 m³/s and 18°C, with the river rated green. Today, 2.5 mm beads are the main choice, stepping up to 3 mm in faster, deeper runs.

Latest Field Update · 9 October 2026

Around 22 m³/s and 18°C — green and highly fishable.

The river is sitting in a very useful Yellowfish range. 2.5 mm tungsten beads are the main go-to today, giving good control through most productive water. In the faster, deeper runs, step up to 3 mm to get the flies down and keep them in the feeding lane.

Go-To Bead2.5 mm

Move to 3 mm in faster, deeper runs.

Current guide call: at around 22 m³/s, start with 2.5 mm tungsten through most runs and seams. Step up to 3 mm where the water is faster or deeper and you need extra weight to reach the feeding depth.

Vaal River Flow Rate Adjustment Table

Use this as a practical starting point, then refine based on clarity, lane speed and how often your flies tick bottom.

Flow (Cumecs)	Water Condition	Bead Size	Strategy
10–20	Low & Clear	2.0–2.5mm	Micro nymphs, longer leaders, stealth and accurate presentation
20–35 (current ~22)	Ideal / Stable	2.5–3.5mm (today: mostly 2.5mm; 3mm faster/deeper)	Standard two-fly Euro rig; adjust weight to lane depth and speed
35–50	Pushy / Higher	3.0–4.0mm	Heavier anchor, tighter control and shorter drifts through softer lanes
50+	High / Coloured	3.5–4.5mm	Short drifts, brighter hotspot flies

Guide Insight: 2.5 mm Is the Main Bead Today

At 22 m³/s, 2.5 mm tungsten beads are doing most of the work. They are giving enough depth while keeping the rig responsive through the majority of productive lanes. In faster, deeper runs, move up to 3 mm to reach the feeding depth and maintain control.
