The Green Choke: Is the Little Red River Losing Its Breath?

There’s a specific kind of silence on the Little Red River right now that should worry anyone who carries a fly rod. Usually, the sound of the river is a symphony of moving water—the rhythmic pulse of Greers Ferry Dam generating power, the gurgle over the shoals at Pangburn, and the steady push that keeps the trout happy and the moss at bay.

But lately, that symphony has been replaced by a stagnant, heavy hush. As we sit deep in the drought of 2026, the Greers Ferry Lake levels are hovering nearly eight feet below normal pool. Because of that, the **Southwestern Power Administration (SWPA)** has pulled back on generation schedules. The result? A river that isn't just low—it’s standing still.

And when the Little Red stands still, the Coontail Moss takes over.

The Rise of the "Green Carpet"

If you’ve been on the river recently, you’ve seen it. Coontail (Ceratophyllum demersum) isn't just a nuisance; it’s an opportunist. Unlike other aquatic plants, Coontail doesn't have true roots; it floats or anchors loosely in the substrate. It thrives in nutrient-rich, slow-moving water.

Without the regular "flush" of high-generation cycles to sweep the riverbed clean and keep the strands manageable, the Coontail has turned into a dense, suffocating carpet.

Why Stagnancy is a Silent Killer

It’s not just about losing a $3 midge because it got snagged in a "salad bar." The problem goes much deeper—literally—into the dissolved oxygen (DO) levels of the river.

The Oxygen Cycle: During the day, all that moss produces oxygen through photosynthesis. But at night, the process reverses. The plants consume oxygen, and as the old moss dies and decays in the stagnant pools, the bacteria breaking it down suck even more oxygen out of the water.

Thermal Stress: Moving water stays cooler. Stagnant water under the Arkansas sun heats up fast. For a cold-water species like our Rainbows and Browns—this is a recipe for disaster.

The Reality Check: A trout in low-oxygen water is a stressed trout. They stop feeding, their immune systems weaken, and in the worst cases, we see "summer kills" that can take years to recover from.

The Case for a Constant Trickle

Here is how I see it: the "all or nothing" approach to water generation is failing the river during these dry spells. When the dam shuts off completely for days at a time, the Little Red becomes a series of disconnected, warm, stagnant ponds. If a spillway was left open—even just a crack—to maintain a constant minimum flow, the impact would be massive:

1. Continuous Aeration: Even a small amount of movement helps break the surface tension and oxygenate the water.

2. Scouring the Moss:A steady current makes it harder for Coontail to "choke out" the shoals. It keeps the gravel clean for the invertebrates (and the fish) to breathe.

3. Temperature Regulation: Moving water doesn't "heat soak" as quickly as a still pool.

We don't need a flood; we just need a pulse.

A Call for Balance

The Little Red River is a world-class fishery, but it’s an artificial one that depends entirely on how we manage the "tap" at the dam. In a year like 2026, where every fish counts and the moss is winning the war, I’d love to see the prioritization for the health of the river over the convenience of the power grid.

Let’s get the water moving. Even a little bit. Because a river that doesn't move is just a long, slow-dying pond—and our trout deserve better than that.

How have you found the moss levels on your last trip out? Are you seeing more "sick" fish in the slack water?
