Fly Fishing Murky Water

I’m fond of trout fishing because I love crystal-clear rivers and streams. They are simply breath-taking and life-giving. So I can get a bit grumpy when a rainstorm adds a bit of color to make the stream more like chocolate milk.

But I’ve learned not to despair. Here are a few insights about fly fishing a murky river or stream:

1. A bit of color may work to your advantage

Sure, a swollen river gushing with snow runoff is usually not productive. Yet, fish are less spooky when the water is a bit murky. The murkiness prevents them from seeing fly fishers, false casts, and larger tippets.

2. Put on the San Juan Worm

There are a couple reasons why a murky river is a great place to try a San Juan Worm.

First, rainstorms and rising water often loosen up mud along the banks. This dislodges worms and sends them drifting down the current. Second, a pattern like a San Juan Worm is a bit larger than a size #18 Zebra Midge, so it’s easier for trout to spot it when visibility is limited.

3. Slow down your fly

Since visibility is limited, you want to give trout a longer-than-usual view of your fly. If you’re fishing nymphs, add a bit more weight to get your fly into the slower current at the bottom of the river. Remember, if the bubbles on the surface are moving faster than your strike indicator, you’re at the right depth. If you’re stripping a streamer, strip it a bit more slowly.

4. Keep an eye out for risers

I’m always surprised to see trout rising when the water is murky. But it happens more often than you might think. Often, I’ll find risers in slower water—either in the tailwater of a pool or even on the outside of a bend. These are places where the fish have more time to respond since the flies on the surface are not being carried along so quickly.

5. Look for fish in unexpected places

A few years ago, I fished the Lower Madison River in Montana when it had more color than usual. When I approached a familiar run, I was surprised to see a couple trout feeding near a shallow bank. I had never seen trout in that spot before. They were always in a deeper channel about six feet further into the river. But with murky water, they were less visible to predators.

I ended up catching one of them.

So don’t give up on fly fishing when your clear-running river gets a bit murky. You can work around a bit of color. Sometimes, it may even work to your advantage.

  1. I like a little color in the water as I do a little drizzle some days . It allows me to get away with a bad cast and gives me a chance to sneak up on fish when most days I can’t. I to find it amazing the fish will take a dry in muddy waters. Yet they do .

  2. This spring the Truckee looked like the Mississippi due to record snow and rain. Literally 5ft higher then used to fishing,but what are you gonna Do? Took a crawdad pattern,found a relatively calm hole,and proceeded to yard nice 20 inch bows out regularly. Never been put off by high water since,almost like it. Thanks
