Water tracing dyes are those used to track or trace the flow of the liquid in question. This is most frequently done for analytical purposes and is a modern evolution of the float tracing method, where an object is thrown into a moving body of water to measure the flow. Water tracing dyes offer a higher level of accuracy and quantitative data than the float tracing method.

Fluorescent dyes are frequently used for water tracing, especially in circumstances of low lighting (such as the water is underground or in cave), or if exceptionally precise data is required.
