Trout fishing in rivers can be more challenging than fishing in lakes. While lakes are primarily still bodies of water, rivers are constantly moving. Anybody can get lucky and catch trout once in a while in any body of water ... but successful anglers know how to "read a river" for potential trout lies (i.e, trout hangouts).
Unfortunately, learning to read rivers doesn't happen overnight. It takes practice. The more you do it, the easier it gets. Having an experienced fishing buddy can help speed up the learning curve. But sadly, many anglers don't have the benefit of somebody else's expertise.
However, thanks to modern technology (and the world wide web), now you can learn just about anything. My good friend Timothy Kusherets (author of Steelhead & Salmon Drift-Fishing Secrets) has created a video showing you how to read a river for trout lies. You can view it below.
This is one of those videos worth watching over again until you start to get the hang of trout fishing in rivers.
