The great thing about channels is that they can occur just about anywhere in a river or stream and are important to trout and their feeding. In summary, a channel is a depression or ridge near a bed. Channels lie in the same direction as the water flow or across the water. What happens is that water bulges on the water's surface as it is deflected and pushed upward.

The depth of a channel can vary dramatically but regardless, they are perfect for trout. Channels can cause water deflection, which serves as a shelter from the flow of the water. This allows the trout to lie perfectly still and not use much energy.

Spotting a channel can be tricky. Although you might be able to spot a deep channel easily, one type of channel called the "Shadow Channel" can be very difficult to detect. This type of channel is actually quite shallow and found in fast moving water.

To detect channels, you want to observe the surface of the water as it flows downstream. The areas you spot that have water coming to the surface appearing, as a bulge is a good sign that there is a channel on the bed.
