Stream Tackle. Simply stated, even in a fast-water environment, trout can be very spooky. The 6 to 8 pound test monofilament you were using to troll for bigger browns on Lake Crowley might be too heavy to catch rainbows on Rush Creek. so, if possible, try to use a lighter, 5 1/2 to 7 foot rod with a little whippier action for most typical stream conditions.
The lighter rods will match better with a 2 to 4 pound test line. This finer diameter monofilament is preferable for streams. The mono will also serve a dual purpose, functioning both as the leader and as the primary line. It is better to fish a stream using the lighter monofilament than to tie knots and use swivels and leader materials since this extra paraphernalia has a tendency to get hung up more in rivers or streams.
The combination of lighter lines and sensitive rods also goes hand in hand with small spinners, spoons and plugs suitable as stream offering. Similarly most of the natural baits are best fished in the moving water with minimal, if any weight. This keeps the bait from sagging on the bottom while maintaining the appearance of food naturally flowing with the current. A lightweight spinning combo is the easiest way to present these baits, maximizing both casting distance and sensitivity.
