telemetry: A method used to track animal movements that relies upon the detection of radio signals at specific frequencies.
threatened species: A designation given to those species that are in danger of becoming endangered in the near future. An example of a threatened species in Montana is the bull trout.
triangulation: A method in telemetry studies used to pinpoint where the exact location of an animal is by relying on the intensity of signals at three different points that form a triangle. The middle point receives the strongest signal.
tributary: A stream that flows into or joins a larger stream (for example, Monture Creek is a tributary to the Blackfoot River).
turbidity: The relative clarity of water. An unclear (poor visibility) stream is usually caused by sediment flowing downstream with the stream current, like during spring runoff.
turbulent: Streamflows, which causes disturbance of the water surface and produces waves. A riffle may be turbulent.
