S8, Ep 36: Navigating High Water: Mac Brown's Strategies for Stained Conditions

Episode Overview

In this Casting Angles segment on The Articulate Fly, host Marvin Cash and veteran guide and Master Casting Instructor Mac Brown tackle one of the most practical — and underappreciated — skill sets in freshwater fly fishing: how to adapt your approach when elevated, stained water follows prolonged rainfall. Recorded against the backdrop of a week of steady rain across western North Carolina, with more forecast ahead, Mac shares a framework for fly selection, water reading and presentation discipline that turns a condition most anglers write off into a genuine tactical advantage.

Mac and Marvin walk through the core principles of fishing stained water: understanding where fish go when visibility drops (higher in the column, into the kitchen riffles), how to match fly color and size to actual visibility rather than habit, and why the grid-tightening approach — spending two to three times longer per spot and halving your grid interval — is the single most important behavioral adjustment for covering dirty water effectively. The conversation also touches on how stained conditions can work in an angler's favor by masking wading noise and allowing closer approaches, and closes with an update on Mac Brown's newly redesigned websites and upcoming fly fishing schools and masterclasses out of Bryson City, North Carolina.

Key Takeaways

• How to position flies higher in the water column when stained conditions push trout and bass off structure and toward the surface.
• Why contrast — not naturalism — is the governing principle for fly selection in dirty water, and how that logic changes depending on whether you're fishing a deep pool or a shallow riffle.
• When to fish dark, high-contrast dry flies (foam or stimulator-style patterns in black or dark gray) versus light-colored nymphs in shallow, broken riffle water where the food is actually concentrated.
• How to use size, shine and sound (rattles) as visibility supplements when natural colors become invisible in tea-colored water.
• Why tightening your grid — cutting your grid interval in half and spending two to three times longer per spot — is essential when fish can't track a fly from distance in low-visibility conditions.
• How stained water tilts the odds in the angler's favor by masking wading noise and enabling closer presentations that would spook fish in clear conditions.

Techniques & Gear Covered

Mac Brown's stained-water framework covers three primary presentations. For dry fly fishing, he advocates dark, high-contrast patterns — black foam bodies, dark brown bodies and black stimulator-style flies — that read clearly against an overcast sky. For nymphing, the key distinction is depth: in deep holes, light penetration is insufficient for fish to see anything, so Mac redirects anglers to shallow riffle heads (what he calls "the kitchen") where fish move to feed and where visibility remains functional in as little as a foot of water. In those shallower zones, he recommends light-colored, small and shiny nymph patterns. Marvin adds that mops and dark stonefly patterns fished with a jigging retrieve are effective for probing stained water more slowly and deliberately, coaxing reluctant fish to commit. Mac references the "Rain X Mop" developed by Jim Estes as an example of a light-colored pattern that works well in shallow riffle water. Rattles are noted as a viable visibility supplement, consistent with the same logic that makes sound important in night fishing. The overarching gear philosophy: let the contrast between fly and water, not the fly's naturalistic fidelity, drive your selection.

FAQ / Key Questions AnsweredHow do I choose fly colors when fishing stained or dirty water?

Mac Brown's core principle is contrast over naturalism: pick a fly color that stands out against the actual background the fish sees, not the color that matches the natural. In overcast conditions with stained water, that means dark dries (black, dark gray) against a light sky, and light or shiny nymphs in shallow zones where the water itself is the dark background. The single rule of thumb is to avoid matching the water's color — a tea-colored fly in tea-colored water is effectively invisible.

Where do trout and bass go when water levels rise and clarity drops?

Both trout and bass move higher in the water column and position themselves in shallower, broken water — particularly riffle heads and foam lines at the head of pools, which Mac calls "the kitchen." These are the zones where dislodged food concentrates and where there's enough ambient light for fish to see. Deep holes become largely unproductive in stained conditions because light penetration is insufficient for fish to spot a fly at depth.

How should I adjust my wading and water coverage in dirty water?

Mac Brown recommends spending two to three times longer in each spot compared to clear-water fishing, and cutting your grid interval roughly in half — from, say, two feet to one foot. Because reduced visibility shortens the distance at which fish can track and respond to a fly, thorough, systematic coverage becomes far more important than covering ground. The goal is to put the fly close enough that the fish almost bumps into it.

Why can stained water actually be an advantage for fly fishers?

Two factors work in the angler's favor when water is stained: fish are less able to detect the angler's presence, which allows closer approaches without spooking; and wading noise is substantially masked by the increased water volume and surface disturbance. Mac Brown notes that he personally prefers fishing in stained conditions for exactly these reasons — the playing field tilts toward the angler who adjusts technique accordingly rather than waiting for clear water.

When should I use dry flies versus nymphs in elevated, stained conditions?

Mac recommends a dry-dropper setup with the dropper kept very close to the surface — not three or four feet down — so that the nymph remains in the productive visibility zone. Dark, high-contrast dries remain viable in stained conditions as long as they're readable against the sky. Pure deep nymphing in pools is largely unproductive; the better bet is redirecting to shallow riffle water where fish are actively feeding and the fly can be seen.
