There are four types of stream trout found in the United States: the brown, rainbow, cutthroat and brook trout. These species reproduce in cold-water streams, rivers and brooks, but stocking keeps their population in lakes where they are unable to breed due to a lack of moving oxygenated water. True lake trout make up a separate species.
Trout in rivers and streams will hide in such places as eddies near boulders and bridge pilings, shallow riffles over a rocky bottom, deep narrow runs between pools, in deeper pools and in undercut banks.
Trout fish are at their most active during the warmth of the afternoon in the spring and fall months; however, they are most active in the morning and evening when the weather gets much hotter in the summer.
The superior sense of smell that trout possess makes live bait fishing for them easier than using lures. Anglers will rig a spinning pole with light line, small hooks and cast out night crawlers, earthworms, crickets, crayfish and minnows among other things to catch them.
People will use lures such as spinners, crankbaits and spoons to catch trout in lakes and moving water.
Fly-fishing for trout is a favorite pastime of many anglers. These individuals are able to make presentations that are more natural with long casts with flies designed to imitate the insects available to a hungry trout in their natural habitat.
Lake trout favor cold water in the range of 48 to 52 degrees Fahrenheit. Therefore, in the summer, these fish will go into the deepest parts of a lake. Anglers will catch them with vertical jigging techniques and by trolling lures in the deep water behind a boat.
