"Tailwater can also refer to a type of fishery. Fishing in tailwaters can be very productive due to consistent water temperature and flow rates found below an impoundment. Nutrients from the lake upstream are released into the tailwater, creating a productive environment in which target fish species, usually trout, can thrive. An example of this phenomenon is the fishery at Lee's Ferry on the Colorado River in Arizona. " - Headwater tailwater
