How We Calculate Fishing Readiness

The readiness score reflects how current and complete a station's public data is — how recently it reported and how many parameters it carries. It is a data-availability signal, not a grade of the water itself. The direct assessment of water conditions — dissolved oxygen, pH, temperature, turbidity and bacteria — is shown on each spot page, where those measured values are evaluated.
