A tailout is a section of a stream or river where the current slows down as it transitions from a deeper pool into a shallower area. This feature often indicates where fish, particularly trout, gather to rest or feed, making it a popular spot for anglers. Tailouts can be characterized by a change in water depth and velocity, typically leading to more favorable conditions for fish. These areas are essential in aquatic ecosystems as they provide habitat and refuge for various species.
