I was able to locate a few nice surface feeding trout last weekend in spite of the full sun and few insects. Their rises were inconsistent and subtle. If I didn’t know the river section I was on real well, I would have never seen them or I should say “hear them”. On the broad shallow flats that I like to fish, below or to the side of a good run, it is often the sound of a rising fish that first catches my attention. When I hear something I focus on the water in the region where I think the sound emanated from. I often take several soft steps up or downstream to change my visual angle depending on the light and glare. Most importantly I try to be patient, refrain from casting and wading, and wait for another sound or even better a surface disruption. Sometimes I hear the fish multiple times before I can actually visually pinpoint its location especially when the lighting situation is challenging. Usually these trout are closer to shore than I originally thought. If I was in a hurry and didn’t take the time to locate them, I probably would wade right through their feeding position, or cast over them and they would be off to the safety of deeper water.
Many drift boats/rafts beach on the flats that I frequent. Anglers generally get out of their boat, immediately wade through the shallow relatively calm flat to reach the main current flow or edge where they repeatedly work their nymph rigs. Usually they catch fish. However with this tactic they miss some of the best visual angling that the river has to offer. Some large trout like to feed lazily on the slow water flats. They slide in from deeper water and position themselves wherever there is some sort of gentle current channeling drifting food. If you can find (see or hear) one of these subtle feeders and make a connection, you are in for a real treat. A large trout hooked on a shallow flat heads for deeper water at breakneck speed. Often they take me into my backing.
When sight-fishing I always try to pick a shallow flat where the sun is going to be on my back. If it is cloudy it does not matter as trout rise more frequently and confidently when the light is low and a hatch, if there is going to be one, will be stronger.
