In this episode, Tom further explores the tactics involved in finding Trout in rivers. As Tom explains, during the day in bright conditions, Trout will often seek areas that provide refuge, only moving into more open water when a hatch starts or when the light fades during the evening. Differing flow rates through the season can also dictate the positions and lies they take up. During the Winter, when flows will be heavier, Trout prefer deeper, slower water, will feed less and be less willing to move to intercept food items. In late Spring and Summer, fish move into faster water where they can intercept the most food, so riffles can be an excellent place to find them. During flooded conditions, Tom explains that the flow rate near the river bed doesn't change that much so Trout will often be in their usual lies but holding the bottom or in slack water near the sides. In the main, the various Trout species live in similar lies in a River but as Tom suggests. Rainbow Trout have a faster metabolism and are better suited to faster water than Cutthroats and Browns. Rainbow Trout are also more migratory and will move up and down the river at will, so just because you caught them in one pool one week, doesn't mean they will be there next. Tom goes on to talk through the various classifications of streams and rivers and their characteristics, which can help provide an insight into the kinds of places to find Trout before you go. Freestone, Limestone, Spring Creeks, Tailwaters all need different approaches and Tom expertly guides us through them.
