Streamer Dredge 30 Breakdown

The Streamer Dredge 30 was designed as our fastest sinking streamer line in lakes or big rivers.

This unique sinking fly line features an aggressive 30 ft head design that loads quickly and shoots large fly’s with minimal false casts. The 30 ft. type 8 (8 IPS) sinking head utilizes our Tungsten Tip Technology to keep your fly at a consistent depth during your retrieve. The intermediate running line removes any hinges in your line.

We built this fly line oversized to properly load fast, modern action rods. A 30 ft. sink tip integrated into the head of this fly line allows for complete versatility when banging banks, working heavy currents, and fishing bigger water. Our signature Shooting Technology decreases friction within the guides for a slick shooting feel throughout its entire life span.

Effectively cover the deepest rivers and lakes with the Streamer Dredge 30 Fly Line.

Our Streamer Dredge 30 fly line is built for cold water environments and will perform best in temperatures between 30 and 70 degrees (F).

We designed this line to get down as fast as possible. Keep your fly down in riffles and heavy current, fish your streamer low & slow during the winter, or instantly get your fly down when casting off a boat.

The black and olive color combination distinguishes the transition between sinking and floating portions of the line, and provides depth reference on your retrieve. These colors are stealthy yet traceable in freshwater environments.

Cleaning your fly line is very important especially when fishing saltwater. Simply pull line off your reel into a clean bucket or tub of freshwater. Put roughly 1oz or more of Cortland’s Line Cleaner solution onto a clean rag or towel. Firmly squeeze the towel with Pro Line Cleaner around the line and slowly pull line through the towel. You should be able to see dirt or discolored streaks on the towel when finished.

Go deep quick

This line did wonders on the Rio Limay in Patagonia, Argentina. You need to get down quick if want to challenge the big silver browns and this line does not disappoint. Only issue I had was the line memory needed addressing all too often.

Streamer fanatic must have!

Ran this line (8wt) during my recent White River, AR trip. Such a great product, sink rate is perfect for the high flows and can throw a large (8+”) streamer well. The running line is a bit stiffer than other brands similar style lines, reducing twists in the line. Nice job Cortland!

Perfect Pyramid line!

Bought the 8/9 and used it on my Pyramid setup this weekend. Orvis Helios 3D 8 weight. Worked perfectly and was able to throw a lot further. Sink rate gets it on the bottom fast which is perfect for Pyramid stripping.
