Deep Holes

Deep holes are usually resting lies but some can also be considered prime lies. A resting lie awards protection from both predation and current force. A deep hole’s depth provides protection from predation and the current. Although many deep holes may lack an abundant food supply such as a riffle can provide, drifting food may still be deposited. Many times deep holes become daytime hiding places; at low light fish migrate to feed in the riffles. Tail outs of deep holes may contain a riffled area. Deeper holes directly downstream from shallow riffles can also become prime lies because emerging insects are delivered directly into these holes. An alarmed fish can quickly return to the depths of the hole for protection.
