How we read the river
Fishing condition ratings combine real-time flow and water temperature from USGS gauges with published thresholds for the Missouri River tailwater fishery. Excellent conditions cluster between 3,000–5,500 cfs and water temperatures of 48–58°F. Always check current angler reports, local guides, and on-the-water observations before making the call.
