About Fishing in Montana
Montana offers diverse fishing opportunities with 1265 water quality monitoring stations tracking conditions across the state. Whether you're looking for bass, trout, catfish, or other species, our real-time water quality data helps you find the best fishing spots.
Understanding Readiness Scores
The readiness score (0–100) reflects how current and complete a station's public data is — how recently it reported and how many parameters it carries — not a grade of the water itself. A higher score means more up-to-date, more complete data. The direct assessment of water conditions (dissolved oxygen, pH, temperature, bacteria) is shown on each spot page, where those measured values are evaluated.
Planning Your Fishing Trip
Before heading out, always check local regulations and obtain the required fishing license. Water quality conditions can change rapidly, so we recommend checking scores on the day of your trip for the most accurate information.
