Tips and Techniques for Rivers
In all cases you are trying to make the fly look natural. These techniques will be different depending on the type of fly you are fishing.
Let’s see how to catch rainbow trout using these different flies.
Nymphs can be fished below an indicator. The indicator helps you see the strike and it also helps keep your fly off the bottom. They are made of yarn, foam or plastic. Sometimes a dry fly is used. A good rule of thumb is put them above the fly about one and a half times the water depth.
Tight line nymph fly fishing calls for about fifteen feet of line past your rod tip. Your goal here is to maintain a tight line from your rod tip to the nymph. You do not use an indicator. You cast upstream and as soon as the fly hits the water you mend (flip) the line so that it is upstream of the fly. After you have cast three or four times, take a few steps upstream and start again.
Sometimes you want to imitate an emerging nymph. To do this you need your fly to rise to the surface. You can do this by casting across and slightly downstream and giving it slack, allowing the fly to sink. After it is near the bottom you lift your rod tip or give it tension, which will cause the fly to rise to the surface. This tactic works well when the water is moving slow or in spring creeks.
Using Dry Flies
Dry flies are fished both upstream and downstream. Either way you need to get them to drift naturally. If the fly starts to drag it will alert the trout that it is not food. There are several tricks you can use to extend a natural drift. These corrections involve using a wiggle cast, a reach cast or a mend (flip of the line). There are many ways to mend the line to avoid an unnatural drift.
Cast your fly across and slightly downstream (or slightly upstream in faster water). Mend the line so that it moves across the river at the same speed it moves down the river. At first, start near the shore and add two or three feet of line after each cast. After you have cast across the stream, take three steps downstream and keep casting out as far as you can. This is the best way to cover the water.
How to Catch Rainbow Trout in Lakes
A countdown and retrieve presentation is the most common technique used on lakes. You use either a sink-tip or full sinking line. After casting, you count (the number will vary) then start retrieving the line at differing speeds.
This is where the guessing begins. You start guessing which depth, which speed and how much you should strip in each time.
A slow retrieve of a nymph just below the surface can sometimes imitate emerging insects. Retrieve the fly about two inches a second. This slow retrieve can drive you crazy after a while.

Knowing how to catch rainbow trout with a fly will require some study. The important part is to present a fly naturally that resembles what the trout are eating that day. Adjust your technique based on the type of fly you are casting and the water you are fishing.
The rewards will be a fun day on the water whether it is on a lake or near a small stream.
Whatever you do, get out there and enjoy the water.
