Classification: no_prediction Confidence: Event provides no calibration value due to unidentified precipitation source - confidence levels remain unchanged
The river showed a minor 0.32 ft rise with no rainfall detected in any band, indicating either measurement noise or very localized precipitation below QPE detection thresholds.

This event presents an interesting case where the gauge recorded a 0.32 ft rise starting at midnight with a sharp hydrograph shape, but no precipitation was detected by QPE in any band, and the gauge precipitation sensor confirmed 0 inches. The rise magnitude is significant enough to be real (above typical measurement noise), yet no rainfall trigger was identified. This could indicate either very localized precipitation below QPE detection thresholds, groundwater contributions, or upstream releases not captured by the watershed model. The sharp hydrograph shape suggests a near-gauge source, which would typically correspond to Band 1 rainfall, but none was detected. Since no prediction was generated due to lack of rainfall triggers, there is no prediction accuracy to evaluate. The event provides limited calibration information since the precipitation source cannot be definitively identified, making any coefficient adjustments speculative.
